Apache Camel Component Reference
Configuration reference for Camel components
Abstract
Chapter 1. Components Overview
This chapter provides a summary of all the components available for Apache Camel.
1.1. Container types
Red Hat Fuse provides a variety of container types, into which you can deploy your Camel applications:
- Spring Boot
- Apache Karaf
- JBoss Enterprise Application Platform (JBoss EAP)
In addition, a Camel application can run as containerless: that is, where a Camel application runs directly in the JVM, without any special container.
In some cases, Fuse might support a Camel component in one container, but not in the others. There are various reasons for this, but in some cases a component is not suitable for all container types. For example, the camel-ejb
component is designed spcifically for Java EE (that is, JBoss EAP), and cannot be supported in the other container types.
1.2. Supported components
Note the following key:
Symbol | Description |
---|---|
✔ | Supported |
❌ | Unsupported or not yet supported |
Deprecated | Likely to be removed in a future release |
Table 1.1, “Apache Camel Component Support Matrix” provides comprehensive details about which Camel components are supported in which containers.

Chapter 2. ActiveMQ
ActiveMQ Component
The ActiveMQ component allows messages to be sent to a JMS Queue or Topic; or messages to be consumed from a JMS Queue or Topic using Apache ActiveMQ.
This component is based on the Chapter 170, JMS Component and uses Spring’s JMS support for declarative transactions, using Spring’s JmsTemplate
for sending and a MessageListenerContainer
for consuming. All the options from the Chapter 170, JMS Component component also apply for this component.
To use this component, make sure you have the activemq.jar
or activemq-core.jar
on your classpath along with any Apache Camel dependencies such as camel-core.jar
, camel-spring.jar
and camel-jms.jar
.
See section Transactions and Cache Levels below on JMS page if you are using transactions with JMS as it can impact performance.
URI format
activemq:[queue:|topic:]destinationName
Where destinationName is an ActiveMQ queue or topic name. By default, the destinationName is interpreted as a queue name. For example, to connect to the queue, FOO.BAR
, use:
activemq:FOO.BAR
You can include the optional queue:
prefix, if you prefer:
activemq:queue:FOO.BAR
To connect to a topic, you must include the topic:
prefix. For example, to connect to the topic, Stocks.Prices
, use:
activemq:topic:Stocks.Prices
Options
See Options on the Chapter 170, JMS Component component as all these options also apply for this component.
Camel on EAP deployment
This component is supported by the Camel on EAP (Wildfly Camel) framework, which offers a simplified deployment model on the Red Hat JBoss Enterprise Application Platform (JBoss EAP) container.
You can configure the ActiveMQ Camel component to work either with an embedded broker or an external broker. To embed a broker in the JBoss EAP container, configure the ActiveMQ Resource Adapter in the EAP container configuration file — for details, see ActiveMQ Resource Adapter Configuration.
Configuring the Connection Factory
The following test case shows how to add an ActiveMQComponent to the CamelContext using the activeMQComponent()
method while specifying the brokerURL used to connect to ActiveMQ.
camelContext.addComponent("activemq", activeMQComponent("vm://localhost?broker.persistent=false"));
Configuring the Connection Factory using Spring XML
You can configure the ActiveMQ broker URL on the ActiveMQComponent as follows
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> <camelContext xmlns="http://camel.apache.org/schema/spring"> </camelContext> <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent"> <property name="brokerURL" value="tcp://somehost:61616"/> </bean> </beans>
Using connection pooling
When sending to an ActiveMQ broker using Camel it’s recommended to use a pooled connection factory to handle efficient pooling of JMS connections, sessions and producers. This is documented in the page ActiveMQ Spring Support.
You can grab Jencks AMQ pool with Maven:
<dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-pool</artifactId> <version>5.3.2</version> </dependency>
And then setup the activemq component as follows:
<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop"> <property name="maxConnections" value="8" /> <property name="connectionFactory" ref="jmsConnectionFactory" /> </bean> <bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration"> <property name="connectionFactory" ref="pooledConnectionFactory"/> <property name="concurrentConsumers" value="10"/> </bean> <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent"> <property name="configuration" ref="jmsConfig"/> </bean>
Notice the init and destroy methods on the pooled connection factory. This is important to ensure the connection pool is properly started and shutdown.
The PooledConnectionFactory
will then create a connection pool with up to 8 connections in use at the same time. Each connection can be shared by many sessions. There is an option named maxActive
you can use to configure the maximum number of sessions per connection; the default value is 500
. From ActiveMQ 5.7 onwards the option has been renamed to better reflect its purpose, being named as maxActiveSessionPerConnection
. Notice the concurrentConsumers
is set to a higher value than maxConnections
is. This is okay, as each consumer is using a session, and as a session can share the same connection, we are in the safe. In this example we can have 8 * 500 = 4000 active sessions at the same time.
Invoking MessageListener POJOs in a route
The ActiveMQ component also provides a helper Type Converter from a JMS MessageListener to a Processor. This means that the Chapter 41, Bean Component component is capable of invoking any JMS MessageListener bean directly inside any route.
So for example you can create a MessageListener in JMS as follows:
public class MyListener implements MessageListener { public void onMessage(Message jmsMessage) { // ... } }
Then use it in your route as follows
from("file://foo/bar"). bean(MyListener.class);
That is, you can reuse any of the Apache Camel components and easily integrate them into your JMS MessageListener
POJO\!
Using ActiveMQ Destination Options
Available as of ActiveMQ 5.6
You can configure the Destination Options in the endpoint uri, using the "destination." prefix. For example to mark a consumer as exclusive, and set its prefetch size to 50, you can do as follows:
<camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="file://src/test/data?noop=true"/> <to uri="activemq:queue:foo"/> </route> <route> <!-- use consumer.exclusive ActiveMQ destination option, notice we have to prefix with destination. --> <from uri="activemq:foo?destination.consumer.exclusive=true&destination.consumer.prefetchSize=50"/> <to uri="mock:results"/> </route> </camelContext>
Consuming Advisory Messages
ActiveMQ can generate Advisory messages which are put in topics that you can consume. Such messages can help you send alerts in case you detect slow consumers or to build statistics (number of messages/produced per day, etc.) The following Spring DSL example shows you how to read messages from a topic.
<route> <from uri="activemq:topic:ActiveMQ.Advisory.Connection?mapJmsMessage=false" /> <convertBodyTo type="java.lang.String"/> <transform> <simple>${in.body} </simple> </transform> <to uri="file://data/activemq/?fileExist=Append&ileName=advisoryConnection-${date:now:yyyyMMdd}.txt" /> </route>
If you consume a message on a queue, you should see the following files under data/activemq folder :
advisoryConnection-20100312.txt advisoryProducer-20100312.txt
and containing string:
ActiveMQMessage {commandId = 0, responseRequired = false, messageId = ID:dell-charles-3258-1268399815140 -1:0:0:0:221, originalDestination = null, originalTransactionId = null, producerId = ID:dell-charles- 3258-1268399815140-1:0:0:0, destination = topic://ActiveMQ.Advisory.Connection, transactionId = null, expiration = 0, timestamp = 0, arrival = 0, brokerInTime = 1268403383468, brokerOutTime = 1268403383468, correlationId = null, replyTo = null, persistent = false, type = Advisory, priority = 0, groupID = null, groupSequence = 0, targetConsumerId = null, compressed = false, userID = null, content = null, marshalledProperties = org.apache.activemq.util.ByteSequence@17e2705, dataStructure = ConnectionInfo {commandId = 1, responseRequired = true, connectionId = ID:dell-charles-3258-1268399815140-2:50, clientId = ID:dell-charles-3258-1268399815140-14:0, userName = , password = *****, brokerPath = null, brokerMasterConnector = false, manageable = true, clientMaster = true}, redeliveryCounter = 0, size = 0, properties = {originBrokerName=master, originBrokerId=ID:dell-charles- 3258-1268399815140-0:0, originBrokerURL=vm://master}, readOnlyProperties = true, readOnlyBody = true, droppable = false}
Getting Component JAR
You need this dependency:
-
activemq-camel
ActiveMQ is an extension of the Chapter 170, JMS Component component released with the ActiveMQ project.
<dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-camel</artifactId> <version>5.6.0</version> </dependency>
Chapter 3. AHC Component
Available as of Camel version 2.8
The ahc: component provides HTTP based endpoints for consuming external HTTP resources (as a client to call external servers using HTTP).
The component uses the Async Http Client library.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-ahc</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
3.1. URI format
ahc:http://hostname[:port][/resourceUri][?options] ahc:https://hostname[:port][/resourceUri][?options]
Will by default use port 80 for HTTP and 443 for HTTPS.
You can append query options to the URI in the following format, ?option=value&option=value&…
3.2. AhcEndpoint Options
The AHC endpoint is configured using URI syntax:
ahc:httpUri
with the following path and query parameters:
3.2.1. Path Parameters (1 parameters):
Name | Description | Default | Type |
---|---|---|---|
httpUri | Required The URI to use such as http://hostname:port/path | URI |
3.2.2. Query Parameters (13 parameters):
Name | Description | Default | Type |
---|---|---|---|
bridgeEndpoint (producer) | If the option is true, then the Exchange.HTTP_URI header is ignored, and use the endpoint’s URI for request. You may also set the throwExceptionOnFailure to be false to let the AhcProducer send all the fault response back. | false | boolean |
bufferSize (producer) | The initial in-memory buffer size used when transferring data between Camel and AHC Client. | 4096 | int |
connectionClose (producer) | Define if the Connection Close header has to be added to HTTP Request. This parameter is false by default | false | boolean |
cookieHandler (producer) | Configure a cookie handler to maintain a HTTP session | CookieHandler | |
headerFilterStrategy (producer) | To use a custom HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
throwExceptionOnFailure (producer) | Option to disable throwing the AhcOperationFailedException in case of failed responses from the remote server. This allows you to get all responses regardless of the HTTP status code. | true | boolean |
transferException (producer) | If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type (for example using Jetty or Servlet Camel components). On the producer side the exception will be deserialized and thrown as is, instead of the AhcOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk. | false | boolean |
binding (advanced) | To use a custom AhcBinding which allows to control how to bind between AHC and Camel. | AhcBinding | |
clientConfig (advanced) | To configure the AsyncHttpClient to use a custom com.ning.http.client.AsyncHttpClientConfig instance. | AsyncHttpClientConfig | |
clientConfigOptions (advanced) | To configure the AsyncHttpClientConfig using the key/values from the Map. | Map | |
synchronous (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean |
clientConfigRealmOptions (security) | To configure the AsyncHttpClientConfig Realm using the key/values from the Map. | Map | |
sslContextParameters (security) | Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility. Note that configuring this option will override any SSL/TLS configuration options provided through the clientConfig option at the endpoint or component level. | SSLContextParameters |
3.3. AhcComponent Options
The AHC component supports 8 options which are listed below.
Name | Description | Default | Type |
---|---|---|---|
client (advanced) | To use a custom AsyncHttpClient | AsyncHttpClient | |
binding (advanced) | To use a custom AhcBinding which allows to control how to bind between AHC and Camel. | AhcBinding | |
clientConfig (advanced) | To configure the AsyncHttpClient to use a custom com.ning.http.client.AsyncHttpClientConfig instance. | AsyncHttpClientConfig | |
sslContextParameters (security) | Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. Note that configuring this option will override any SSL/TLS configuration options provided through the clientConfig option at the endpoint or component level. | SSLContextParameters | |
allowJavaSerialized Object (advanced) | Whether to allow java serialization when a request uses context-type=application/x-java-serialized-object This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk. | false | boolean |
useGlobalSslContext Parameters (security) | Enable usage of global SSL context parameters. | false | boolean |
headerFilterStrategy (filter) | To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
resolveProperty Placeholders (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean |
Notice that setting any of the options on the AhcComponent
will propagate those options to AhcEndpoints
being created. However the AhcEndpoint
can also configure/override a custom option. Options set on endpoints will always take precedence over options from the AhcComponent
.
3.4. Message Headers
Name | Type | Description |
---|---|---|
|
| URI to call. Will override existing URI set directly on the endpoint. |
|
|
Request URI’s path, the header will be used to build the request URI with the HTTP_URI. If the path is start with "/", http producer will try to find the relative path based on the Exchange.HTTP_BASE_URI header or the |
|
| Camel 2.11 onwards: URI parameters. Will override existing URI parameters set directly on the endpoint. |
|
| The HTTP response code from the external server. Is 200 for OK. |
|
| Character encoding. |
|
|
The HTTP content type. Is set on both the IN and OUT message to provide a content type, such as |
|
|
The HTTP content encoding. Is set on both the IN and OUT message to provide a content encoding, such as |
3.5. Message Body
Camel will store the HTTP response from the external server on the OUT body. All headers from the IN message will be copied to the OUT message, so headers are preserved during routing. Additionally Camel will add the HTTP response headers as well to the OUT message headers.
3.6. Response code
Camel will handle according to the HTTP response code:
- Response code is in the range 100..299, Camel regards it as a success response.
-
Response code is in the range 300..399, Camel regards it as a redirection response and will throw a
AhcOperationFailedException
with the information. Response code is 400+, Camel regards it as an external server failure and will throw a
AhcOperationFailedException
with the information.throwExceptionOnFailure
The option,
throwExceptionOnFailure
, can be set tofalse
to prevent theAhcOperationFailedException
from being thrown for failed response codes. This allows you to get any response from the remote server.
3.7. AhcOperationFailedException
This exception contains the following information:
- The HTTP status code
- The HTTP status line (text of the status code)
- Redirect location, if server returned a redirect
-
Response body as a
java.lang.String
, if server provided a body as response
3.8. Calling using GET or POST
The following algorithm is used to determine if either GET
or POST
HTTP method should be used:
1. Use method provided in header.
2. GET
if query string is provided in header.
3. GET
if endpoint is configured with a query string.
4. POST
if there is data to send (body is not null).
5. GET
otherwise.
3.9. Configuring URI to call
You can set the HTTP producer’s URI directly form the endpoint URI. In the route below, Camel will call out to the external server, oldhost
, using HTTP.
from("direct:start") .to("ahc:http://oldhost");
And the equivalent Spring sample:
<camelContext xmlns="http://activemq.apache.org/camel/schema/spring"> <route> <from uri="direct:start"/> <to uri="ahc:http://oldhost"/> </route> </camelContext>
You can override the HTTP endpoint URI by adding a header with the key, Exchange.HTTP_URI
, on the message.
from("direct:start") .setHeader(Exchange.HTTP_URI, constant("http://newhost")) .to("ahc:http://oldhost");
3.10. Configuring URI Parameters
The ahc producer supports URI parameters to be sent to the HTTP server. The URI parameters can either be set directly on the endpoint URI or as a header with the key Exchange.HTTP_QUERY
on the message.
from("direct:start") .to("ahc:http://oldhost?order=123&detail=short");
Or options provided in a header:
from("direct:start") .setHeader(Exchange.HTTP_QUERY, constant("order=123&detail=short")) .to("ahc:http://oldhost");
3.11. How to set the http method to the HTTP producer
The HTTP component provides a way to set the HTTP request method by setting the message header. Here is an example;
from("direct:start") .setHeader(Exchange.HTTP_METHOD, constant("POST")) .to("ahc:http://www.google.com") .to("mock:results");
And the equivalent Spring sample:
<camelContext xmlns="http://activemq.apache.org/camel/schema/spring"> <route> <from uri="direct:start"/> <setHeader headerName="CamelHttpMethod"> <constant>POST</constant> </setHeader> <to uri="ahc:http://www.google.com"/> <to uri="mock:results"/> </route> </camelContext>
3.12. Configuring charset
If you are using POST
to send data you can configure the charset
using the Exchange
property:
exchange.setProperty(Exchange.CHARSET_NAME, "iso-8859-1");
3.12.1. URI Parameters from the endpoint URI
In this sample we have the complete URI endpoint that is just what you would have typed in a web browser. Multiple URI parameters can of course be set using the &
character as separator, just as you would in the web browser. Camel does no tricks here.
// we query for Camel at the Google page template.sendBody("ahc:http://www.google.com/search?q=Camel", null);
3.12.2. URI Parameters from the Message
Map headers = new HashMap(); headers.put(Exchange.HTTP_QUERY, "q=Camel&lr=lang_en"); // we query for Camel and English language at Google template.sendBody("ahc:http://www.google.com/search", null, headers);
In the header value above notice that it should not be prefixed with ?
and you can separate parameters as usual with the &
char.
3.12.3. Getting the Response Code
You can get the HTTP response code from the AHC component by getting the value from the Out message header with Exchange.HTTP_RESPONSE_CODE
.
Exchange exchange = template.send("ahc:http://www.google.com/search", new Processor() { public void process(Exchange exchange) throws Exception { exchange.getIn().setHeader(Exchange.HTTP_QUERY, constant("hl=en&q=activemq")); } }); Message out = exchange.getOut(); int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);
3.13. Configuring AsyncHttpClient
The AsyncHttpClient
client uses a AsyncHttpClientConfig
to configure the client. See the documentation at
Async Http Client for more details.
In Camel 2.8, configuration is limited to using the builder pattern provided by AsyncHttpClientConfig.Builder
. In Camel 2.8, the AsyncHttpClientConfig
doesn’t support getters/setters so its not easy to create/configure using a Spring bean style (eg the <bean> tag in the XML file).
The example below shows how to use a builder to create the AsyncHttpClientConfig
which we configure on the AhcComponent
.
In Camel 2.9, the AHC component uses Async HTTP library 1.6.4. This newer version provides added support for plain bean style configuration. The AsyncHttpClientConfigBean
class provides getters and setters for the configuration options available in AsyncHttpClientConfig
. An instance of AsyncHttpClientConfigBean
may be passed directly to the AHC component or referenced in an endpoint URI using the clientConfig
URI parameter.
Also available in Camel 2.9 is the ability to set configuration options directly in the URI. URI parameters starting with "clientConfig." can be used to set the various configurable properties of AsyncHttpClientConfig
. The properties specified in the endpoint URI are merged with those specified in the configuration referenced by the "clientConfig" URI parameter with those being set using the "clientConfig." parameter taking priority. The AsyncHttpClientConfig
instance referenced is always copied for each endpoint such that settings on one endpoint will remain independent of settings on any previously created endpoints. The example below shows how to configure the AHC component using the "clientConfig." type URI parameters.
from("direct:start") .to("ahc:http://localhost:8080/foo?clientConfig.maxRequestRetry=3&clientConfig.followRedirects=true")
3.14. SSL Support (HTTPS)
Using the JSSE Configuration Utility
As of Camel 2.9, the AHC component supports SSL/TLS configuration through the Camel JSSE Configuration Utility. This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels. The following examples demonstrate how to use the utility with the AHC component.
Programmatic configuration of the component
KeyStoreParameters ksp = new KeyStoreParameters(); ksp.setResource("/users/home/server/keystore.jks"); ksp.setPassword("keystorePassword"); KeyManagersParameters kmp = new KeyManagersParameters(); kmp.setKeyStore(ksp); kmp.setKeyPassword("keyPassword"); SSLContextParameters scp = new SSLContextParameters(); scp.setKeyManagers(kmp); AhcComponent component = context.getComponent("ahc", AhcComponent.class); component.setSslContextParameters(scp));
Spring DSL based configuration of endpoint
... <camel:sslContextParameters id="sslContextParameters"> <camel:keyManagers keyPassword="keyPassword"> <camel:keyStore resource="/users/home/server/keystore.jks" password="keystorePassword"/> </camel:keyManagers> </camel:sslContextParameters>... ... <to uri="ahc:https://localhost/foo?sslContextParameters=#sslContextParameters"/> ...

Chapter 4. AHC Websocket Component
Available as of Camel version 2.14
The ahc-ws component provides Websocket based endpoints for a client communicating with external servers over Websocket (as a client opening a websocket connection to an external server).
The component uses the AHC component that in turn uses the Async Http Client library.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-ahc-ws</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
4.1. URI Format
ahc-ws://hostname[:port][/resourceUri][?options] ahc-wss://hostname[:port][/resourceUri][?options]
Will by default use port 80 for ahc-ws and 443 for ahc-wss.
4.2. AHC-WS Options
As the AHC-WS component is based on the AHC component, you can use the various configuration options of the AHC component.
The AHC Websocket component supports 8 options which are listed below.
Name | Description | Default | Type |
---|---|---|---|
client (advanced) | To use a custom AsyncHttpClient | AsyncHttpClient | |

The AHC Websocket endpoint is configured using URI syntax:
ahc-ws:httpUri
with the following path and query parameters:
4.2.1. Path Parameters (1 parameters):
Name | Description | Default | Type |
---|---|---|---|
httpUri | Required The URI to use such as http://hostname:port/path | URI |
4.2.2. Query Parameters (18 parameters):
Name | Description | Default | Type |
---|---|---|---|
bridgeEndpoint (common) | If the option is true, then the Exchange.HTTP_URI header is ignored, and use the endpoint’s URI for request. You may also set the throwExceptionOnFailure to be false to let the AhcProducer send all the fault response back. | false | boolean |
bufferSize (common) | The initial in-memory buffer size used when transferring data between Camel and AHC Client. | 4096 | int |
headerFilterStrategy (common) | To use a custom HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |

transferException (common) | If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type (for example using Jetty or Servlet Camel components). On the producer side the exception will be deserialized and thrown as is, instead of the AhcOperationFailedException. The caused exception is required to be serialized. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk. | false | boolean |
bridgeErrorHandler (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean |
sendMessageOnError (consumer) | Whether to send an message if the web-socket listener received an error. | false | boolean |
exceptionHandler (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. | ExceptionHandler | |

sslContextParameters (security) | Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility. Note that configuring this option will override any SSL/TLS configuration options provided through the clientConfig option at the endpoint or component level. | SSLContextParameters |
4.3. Writing and Reading Data over Websocket
An ahc-ws endpoint can either write data to the socket or read from the socket, depending on whether the endpoint is configured as the producer or the consumer, respectively.
4.4. Configuring URI to Write or Read Data
In the route below, Camel will write to the specified websocket connection.
from("direct:start") .to("ahc-ws://targethost");
And the equivalent Spring sample:
<camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="direct:start"/> <to uri="ahc-ws://targethost"/> </route> </camelContext>
In the route below, Camel will read from the specified websocket connection.

Chapter 5. AMQP Component
Available as of Camel version 1.2
The amqp: component supports the AMQP 1.0 protocol using the JMS Client API of the Qpid project. In case you want to use AMQP 0.9 (in particular RabbitMQ) you might also be interested in the Camel RabbitMQ component. Please keep in mind that prior to the Camel 2.17.0 AMQP component supported AMQP 0.9 and above, however since Camel 2.17.0 it supports only AMQP 1.0.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-amqp</artifactId> <version>${camel.version}</version> <!-- use the same version as your Camel core version --> </dependency>
5.1. URI format
amqp:[queue:|topic:]destinationName[?options]
5.2. AMQP Options
You can specify all of the various configuration options of the JMS component after the destination name.
The AMQP component supports 80 options which are listed below.
Name | Description | Default | Type |
---|---|---|---|
configuration (advanced) | To use a shared JMS configuration | JmsConfiguration | |
acceptMessagesWhile Stopping (consumer) | Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option. | false | boolean |
allowReplyManagerQuick Stop (consumer) | Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag. | false | boolean |
acknowledgementMode (consumer) | The JMS acknowledgement mode defined as an Integer. Allows you to set vendor-specific extensions to the acknowledgment mode.For the regular modes, it is preferable to use the acknowledgementModeName instead. | int | |
eagerLoadingOf Properties (consumer) | Enables eager loading of JMS properties as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties | false | boolean |
acknowledgementModeName (consumer) | The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE | AUTO_ ACKNOWLEDGE | String |
autoStartup (consumer) | Specifies whether the consumer container should auto-startup. | true | boolean |
cacheLevel (consumer) | Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details. | int | |
cacheLevelName (consumer) | Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information. | CACHE_AUTO | String |
replyToCacheLevelName (producer) | Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION. | String | |
clientId (common) | Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead. | String | |
concurrentConsumers (consumer) | Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. | 1 | int |
replyToConcurrent Consumers (producer) | Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. | 1 | int |
connectionFactory (common) | The connection factory to be use. A connection factory must be configured either on the component or endpoint. | ConnectionFactory | |
username (security) | Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. | String | |
password (security) | Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. | String | |
deliveryPersistent (producer) | Specifies whether persistent delivery is used by default. | true | boolean |
deliveryMode (producer) | Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2. | Integer | |
durableSubscriptionName (common) | The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well. | String | |
exceptionListener (advanced) | Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. | ExceptionListener | |
errorHandler (advanced) | Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. | ErrorHandler | |
errorHandlerLogging Level (logging) | Allows to configure the default errorHandler logging level for logging uncaught exceptions. | WARN | LoggingLevel |
errorHandlerLogStack Trace (logging) | Allows to control whether stacktraces should be logged or not, by the default errorHandler. | true | boolean |
explicitQosEnabled (producer) | Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers. | false | boolean |
exposeListenerSession (consumer) | Specifies whether the listener session should be exposed when consuming messages. | false | boolean |
idleTaskExecutionLimit (advanced) | Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring. | 1 | int |
idleConsumerLimit (advanced) | Specify the limit for the number of consumers that are allowed to be idle at any given time. | 1 | int |
maxConcurrentConsumers (consumer) | Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. | int | |
replyToMaxConcurrent Consumers (producer) | Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. | int | |
replyOnTimeoutToMax ConcurrentConsumers (producer) | Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS. | 1 | int |
maxMessagesPerTask (advanced) | The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required. | -1 | int |
messageConverter (advanced) | To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message. | MessageConverter | |
mapJmsMessage (advanced) | Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc. | true | boolean |
messageIdEnabled (advanced) | When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value | true | boolean |
messageTimestampEnabled (advanced) | Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value | true | boolean |
alwaysCopyMessage (producer) | If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set) | false | boolean |
useMessageIDAs CorrelationID (advanced) | Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages. | false | boolean |
priority (producer) | Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect. | 4 | int |
pubSubNoLocal (advanced) | Specifies whether to inhibit the delivery of messages published by its own connection. | false | boolean |
receiveTimeout (advanced) | The timeout for receiving messages (in milliseconds). | 1000 | long |
recoveryInterval (advanced) | Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. | 5000 | long |
taskExecutor (consumer) | Allows you to specify a custom task executor for consuming messages. | TaskExecutor | |
timeToLive (producer) | When sending messages, specifies the time-to-live of the message (in milliseconds). | -1 | long |
transacted (transaction) | Specifies whether to use transacted mode | false | boolean |
lazyCreateTransaction Manager (transaction) | If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true. | true | boolean |
transactionManager (transaction) | The Spring transaction manager to use. | PlatformTransaction Manager | |
transactionName (transaction) | The name of the transaction to use. | String | |
transactionTimeout (transaction) | The timeout value of the transaction (in seconds), if using transacted mode. | -1 | int |
testConnectionOn Startup (common) | Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well. | false | boolean |
asyncStartListener (advanced) | Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry. | false | boolean |
asyncStopListener (advanced) | Whether to stop the JmsConsumer message listener asynchronously, when stopping a route. | false | boolean |
forceSendOriginal Message (producer) | When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received. | false | boolean |
requestTimeout (producer) | The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. | 20000 | long |
requestTimeoutChecker Interval (advanced) | Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. | 1000 | long |
transferExchange (advanced) | You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. | false | boolean |
transferException (advanced) | If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. | false | boolean |
transferFault (advanced) | If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on MessageisFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstantsJMS_TRANSFER_FAULTJMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws. | false | boolean |
jmsOperations (advanced) | Allows you to use your own implementation of the org.springframework.jms.core.JmsOperations interface. Camel uses JmsTemplate as default. Can be used for testing purpose, but not used much as stated in the spring API docs. | JmsOperations | |
destinationResolver (advanced) | A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). | DestinationResolver | |
replyToType (producer) | Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive. | ReplyToType | |
preserveMessageQos (producer) | Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header. | false | boolean |
asyncConsumer (consumer) | Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions). | false | boolean |
allowNullBody (producer) | Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown. | true | boolean |
includeSentJMS MessageID (producer) | Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination. | false | boolean |
includeAllJMSX Properties (advanced) | Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply. | false | boolean |
defaultTaskExecutor Type (consumer) | Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers. | DefaultTaskExecutor Type | |
jmsKeyFormatStrategy (advanced) | Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation. | JmsKeyFormatStrategy | |
allowAdditionalHeaders (producer) | This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching. | String | |
queueBrowseStrategy (advanced) | To use a custom QueueBrowseStrategy when browsing queues | QueueBrowseStrategy | |
messageCreatedStrategy (advanced) | To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message. | MessageCreatedStrategy | |
waitForProvision CorrelationToBeUpdated Counter (advanced) | Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled. | 50 | int |
waitForProvision CorrelationToBeUpdated ThreadSleepingTime (advanced) | Interval in millis to sleep each time while waiting for provisional correlation id to be updated. | 100 | long |
correlationProperty (producer) | Use this JMS property to correlate messages in InOut exchange pattern (request-reply) instead of JMSCorrelationID property. This allows you to exchange messages with systems that do not correlate messages using JMSCorrelationID JMS property. If used JMSCorrelationID will not be used or set by Camel. The value of here named property will be generated if not supplied in the header of the message under the same name. | String | |
subscriptionDurable (consumer) | Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. | false | boolean |
subscriptionShared (consumer) | Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker. | false | boolean |
subscriptionName (consumer) | Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0). | String | |
streamMessageType Enabled (producer) | Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data. | false | boolean |
formatDateHeadersTo Iso8601 (producer) | Sets whether date headers should be formatted according to the ISO 8601 standard. | false | boolean |
headerFilterStrategy (filter) | To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
resolveProperty Placeholders (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean |
The AMQP endpoint is configured using URI syntax:
amqp:destinationType:destinationName
with the following path and query parameters:
5.2.1. Path Parameters (2 parameters):
Name | Description | Default | Type |
---|---|---|---|
destinationType | The kind of destination to use | queue | String |
destinationName | Required Name of the queue or topic to use as destination | String |
5.2.2. Query Parameters (91 parameters):
Name | Description | Default | Type |
---|---|---|---|
clientId (common) | Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead. | String | |
connectionFactory (common) | The connection factory to be use. A connection factory must be configured either on the component or endpoint. | ConnectionFactory | |
disableReplyTo (common) | Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another. | false | boolean |
durableSubscriptionName (common) | The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well. | String | |
jmsMessageType (common) | Allows you to force the use of a specific javax.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it. | JmsMessageType | |
testConnectionOnStartup (common) | Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well. | false | boolean |
acknowledgementModeName (consumer) | The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE | AUTO_ ACKNOWLEDGE | String |
asyncConsumer (consumer) | Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions). | false | boolean |
autoStartup (consumer) | Specifies whether the consumer container should auto-startup. | true | boolean |
bridgeErrorHandler (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean |
cacheLevel (consumer) | Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details. | int | |
cacheLevelName (consumer) | Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information. | CACHE_AUTO | String |
concurrentConsumers (consumer) | Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. | 1 | int |
maxConcurrentConsumers (consumer) | Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. | int | |
replyTo (consumer) | Provides an explicit ReplyTo destination, which overrides any incoming value of Message.getJMSReplyTo(). | String | |
replyToDeliveryPersistent (consumer) | Specifies whether to use persistent delivery by default for replies. | true | boolean |
selector (consumer) | Sets the JMS selector to use | String | |
subscriptionDurable (consumer) | Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. | false | boolean |
subscriptionName (consumer) | Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0). | String | |
subscriptionShared (consumer) | Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker. | false | boolean |
acceptMessagesWhileStopping (consumer) | Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option. | false | boolean |
allowReplyManagerQuickStop (consumer) | Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag. | false | boolean |
consumerType (consumer) | The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use. | Default | ConsumerType |
defaultTaskExecutorType (consumer) | Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers. | DefaultTaskExecutor Type | |
eagerLoadingOfProperties (consumer) | Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties | false | boolean |
exceptionHandler (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. | ExceptionHandler | |
exchangePattern (consumer) | Sets the exchange pattern when the consumer creates an exchange. | ExchangePattern | |
exposeListenerSession (consumer) | Specifies whether the listener session should be exposed when consuming messages. | false | boolean |
replyToSameDestination Allowed (consumer) | Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself. | false | boolean |
taskExecutor (consumer) | Allows you to specify a custom task executor for consuming messages. | TaskExecutor | |
deliveryMode (producer) | Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2. | Integer | |
deliveryPersistent (producer) | Specifies whether persistent delivery is used by default. | true | boolean |
explicitQosEnabled (producer) | Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers. | false | Boolean |
formatDateHeadersToIso8601 (producer) | Sets whether JMS date properties should be formatted according to the ISO 8601 standard. | false | boolean |
preserveMessageQos (producer) | Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header. | false | boolean |
priority (producer) | Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect. | 4 | int |
replyToConcurrentConsumers (producer) | Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. | 1 | int |
replyToMaxConcurrent Consumers (producer) | Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. | int | |
replyToOnTimeoutMax ConcurrentConsumers (producer) | Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS. | 1 | int |
replyToOverride (producer) | Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination. | String | |
replyToType (producer) | Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive. | ReplyToType | |
requestTimeout (producer) | The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. | 20000 | long |
timeToLive (producer) | When sending messages, specifies the time-to-live of the message (in milliseconds). | -1 | long |
allowAdditionalHeaders (producer) | This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching. | String | |
allowNullBody (producer) | Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown. | true | boolean |
alwaysCopyMessage (producer) | If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set) | false | boolean |
correlationProperty (producer) | When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel. | String | |
disableTimeToLive (producer) | Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details. | false | boolean |
forceSendOriginalMessage (producer) | When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received. | false | boolean |
includeSentJMSMessageID (producer) | Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination. | false | boolean |
replyToCacheLevelName (producer) | Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION. | String | |
replyToDestinationSelector Name (producer) | Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue). | String | |
streamMessageTypeEnabled (producer) | Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data. | false | boolean |
allowSerializedHeaders (advanced) | Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. | false | boolean |
asyncStartListener (advanced) | Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry. | false | boolean |
asyncStopListener (advanced) | Whether to stop the JmsConsumer message listener asynchronously, when stopping a route. | false | boolean |
destinationResolver (advanced) | A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). | DestinationResolver | |
errorHandler (advanced) | Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. | ErrorHandler | |
exceptionListener (advanced) | Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. | ExceptionListener | |
headerFilterStrategy (advanced) | To use a custom HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
idleConsumerLimit (advanced) | Specify the limit for the number of consumers that are allowed to be idle at any given time. | 1 | int |
idleTaskExecutionLimit (advanced) | Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring. | 1 | int |
includeAllJMSXProperties (advanced) | Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply. | false | boolean |
jmsKeyFormatStrategy (advanced) | Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation. | String | |
mapJmsMessage (advanced) | Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc. | true | boolean |
maxMessagesPerTask (advanced) | The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required. | -1 | int |
messageConverter (advanced) | To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message. | MessageConverter | |
messageCreatedStrategy (advanced) | To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message. | MessageCreatedStrategy | |
messageIdEnabled (advanced) | When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value | true | boolean |
messageListenerContainer Factory (advanced) | Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom. | MessageListener ContainerFactory | |
messageTimestampEnabled (advanced) | Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value | true | boolean |
pubSubNoLocal (advanced) | Specifies whether to inhibit the delivery of messages published by its own connection. | false | boolean |
receiveTimeout (advanced) | The timeout for receiving messages (in milliseconds). | 1000 | long |
recoveryInterval (advanced) | Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. | 5000 | long |
requestTimeoutChecker Interval (advanced) | Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. | 1000 | long |
synchronous (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean |
transferException (advanced) | If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. | false | boolean |
transferExchange (advanced) | You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. | false | boolean |
transferFault (advanced) | If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on MessageisFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstantsJMS_TRANSFER_FAULTJMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws. | false | boolean |
useMessageIDAsCorrelation ID (advanced) | Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages. | false | boolean |
waitForProvisionCorrelation ToBeUpdatedCounter (advanced) | Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled. | 50 | int |
waitForProvisionCorrelation ToBeUpdatedThreadSleeping Time (advanced) | Interval in millis to sleep each time while waiting for provisional correlation id to be updated. | 100 | long |

transactionManager (transaction) | The Spring transaction manager to use. | PlatformTransaction Manager | |
transactionName (transaction) | The name of the transaction to use. | String | |
transactionTimeout (transaction) | The timeout value of the transaction (in seconds), if using transacted mode. | -1 | int |
5.3. Usage
As AMQP component is inherited from JMS component, the usage of the former is almost identical to the latter:
Using AMQP component
// Consuming from AMQP queue from("amqp:queue:incoming"). to(...); // Sending message to the AMQP topic from(...). to("amqp:topic:notify");
5.4. Configuring AMQP component
Starting from the Camel 2.16.1 you can also use the AMQPComponent#amqp10Component(String connectionURI)
factory method to return the AMQP 1.0 component with the pre-configured topic prefix:
Creating AMQP 1.0 component
AMQPComponent amqp = AMQPComponent.amqp10Component("amqp://guest:guest@localhost:5672");
Keep in mind that starting from the Camel 2.17 the AMQPComponent#amqp10Component(String connectionURI)
factory method has been deprecated on the behalf of the AMQPComponent#amqpComponent(String connectionURI)
:
Creating AMQP 1.0 component
AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672"); AMQPComponent authorizedAmqp = AMQPComponent.amqpComponent("amqp://localhost:5672", "user", "password");
Starting from Camel 2.17, in order to automatically configure the AMQP component, you can also add an instance of org.apache.camel.component.amqp.AMQPConnectionDetails
to the registry. For example for Spring Boot you just have to define bean:
AMQP connection details auto-configuration
@Bean AMQPConnectionDetails amqpConnection() { return new AMQPConnectionDetails("amqp://localhost:5672"); } @Bean AMQPConnectionDetails securedAmqpConnection() { return new AMQPConnectionDetails("amqp://lcoalhost:5672", "username", "password"); }
Likewise, you can also use CDI producer methods when using Camel-CDI
AMQP connection details auto-configuration for CDI
@Produces AMQPConnectionDetails amqpConnection() { return new AMQPConnectionDetails("amqp://localhost:5672"); }
You can also rely on the Camel properties to read the AMQP connection details. Factory method AMQPConnectionDetails.discoverAMQP()
attempts to read Camel properties in a Kubernetes-like convention, just as demonstrated on the snippet below:
AMQP connection details auto-configuration
export AMQP_SERVICE_HOST = "mybroker.com" export AMQP_SERVICE_PORT = "6666" export AMQP_SERVICE_USERNAME = "username" export AMQP_SERVICE_PASSWORD = "password" ... @Bean AMQPConnectionDetails amqpConnection() { return AMQPConnectionDetails.discoverAMQP(); }
Enabling AMQP specific options
If you, for example, need to enable amqp.traceFrames
you can do that by appending the option to your URI, like the following example:
AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672?amqp.traceFrames=true");
For reference take a look at the QPID JMS client configuration
5.5. Using topics
To have using topics working with camel-amqp
you need to configure the component to use topic://
as topic prefix, as shown below:
<bean id="amqp" class="org.apache.camel.component.amqp.AmqpComponent"> <property name="connectionFactory"> <bean class="org.apache.qpid.jms.JmsConnectionFactory" factory-method="createFromURL"> <property name="remoteURI" value="amqp://localhost:5672" /> <property name="topicPrefix" value="topic://" /> <!-- only necessary when connecting to ActiveMQ over AMQP 1.0 --> </bean> </property> </bean>
Keep in mind that both AMQPComponent#amqpComponent()
methods and AMQPConnectionDetails
pre-configure the component with the topic prefix, so you don’t have to configure it explicitly.

Chapter 6. APNS Component
Available as of Camel version 2.8
The apns component is used for sending notifications to iOS devices. The apns components use javapns library.
The component supports sending notifications to Apple Push Notification Servers (APNS) and consuming feedback from the servers.
The consumer is configured with 3600 seconds for polling by default because it is a best practice to consume feedback stream from Apple Push Notification Servers only from time to time. For example: every 1 hour to avoid flooding the servers.
The feedback stream gives informations about inactive devices. You only need to get this informations every some hours if your mobile application is not a heavily used one.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-apns</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
6.1. URI format
To send notifications:
apns:notify[?options]
To consume feedback:
apns:consumer[?options]
6.2. Options
The APNS component supports 2 options which are listed below.
Name | Description | Default | Type |
---|---|---|---|
apnsService (common) | Required The ApnsService to use. The org.apache.camel.component.apns.factory.ApnsServiceFactory can be used to build a ApnsService | ApnsService | |
resolveProperty Placeholders (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean |
The APNS endpoint is configured using URI syntax:
apns:name
with the following path and query parameters:
6.2.1. Path Parameters (1 parameters):
Name | Description | Default | Type |
---|---|---|---|
name | Name of the endpoint | String |
6.2.2. Query Parameters (20 parameters):
Name | Description | Default | Type |
---|---|---|---|
tokens (common) | Configure this property in case you want to statically declare tokens related to devices you want to notify. Tokens are separated by comma. | String | |
bridgeErrorHandler (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean |
sendEmptyMessageWhenIdle (consumer) | If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead. | false | boolean |
exceptionHandler (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. | ExceptionHandler | |
exchangePattern (consumer) | Sets the exchange pattern when the consumer creates an exchange. | ExchangePattern | |
pollStrategy (consumer) | A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel. | PollingConsumerPoll Strategy | |
synchronous (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean |
backoffErrorThreshold (scheduler) | The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in. | int | |
backoffIdleThreshold (scheduler) | The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. | int | |
backoffMultiplier (scheduler) | To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured. | int | |
delay (scheduler) | Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). | 500 | long |
greedy (scheduler) | If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages. | false | boolean |
initialDelay (scheduler) | Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). | 1000 | long |
runLoggingLevel (scheduler) | The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. | TRACE | LoggingLevel |
scheduledExecutorService (scheduler) | Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool. | ScheduledExecutor Service | |
scheduler (scheduler) | To use a cron scheduler from either camel-spring or camel-quartz2 component | none | ScheduledPollConsumer Scheduler |
schedulerProperties (scheduler) | To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler. | Map | |
startScheduler (scheduler) | Whether the scheduler should be auto started. | true | boolean |
timeUnit (scheduler) | Time unit for initialDelay and delay options. | MILLISECONDS | TimeUnit |
useFixedDelay (scheduler) | Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details. | true | boolean |
You can append query options to the URI in the following format, ?option=value&option=value&…
6.2.3. Component
The ApnsComponent
must be configured with a com.notnoop.apns.ApnsService
. The service can be created and configured using the org.apache.camel.component.apns.factory.ApnsServiceFactory
. See further below for an example. And as well in the test source code.
6.2.3.1. SSL Setting
In order to use secure connection, an instance of org.apache.camel.util.jsse.SSLContextParameters
should be injected to org.apache.camel.component.apns.factory.ApnsServiceFactory
which is used to configure the component. See the test resources for an example. ssl example
6.3. Exchange data format
When Camel will fetch feedback data corresponding to inactive devices, it will retrieve a List of InactiveDevice objects. Each InactiveDevice object of the retrieved list will be setted as the In body, and then processed by the consumer endpoint.
6.4. Message Headers
Camel Apns uses these headers.
Property | Default | Description |
---|---|---|
| Empty by default. | |
|
| In case you choose PAYLOAD for the message type, then the message will be considered as a APNS payload and sent as is. In case you choose STRING, message will be converted as a APNS payload. From Camel 2.16 onwards APNS_NOTIFICATION is used for sending message body as com.notnoop.apns.ApnsNotification types. |
6.5. ApnsServiceFactory builder callback
ApnsServiceFactory
comes with the empty callback method that could be used to configure (or even replace) the default ApnsServiceBuilder
instance. The signature of the method could look as follows:
protected ApnsServiceBuilder configureServiceBuilder(ApnsServiceBuilder serviceBuilder);
And could be used like as follows:
ApnsServiceFactory proxiedApnsServiceFactory = new ApnsServiceFactory(){ @Override protected ApnsServiceBuilder configureServiceBuilder(ApnsServiceBuilder serviceBuilder) { return serviceBuilder.withSocksProxy("my.proxy.com", 6666); } };

Chapter 7. ASN.1 File DataFormat
Available as of Camel version 2.20
The ASN.1 Data Format Data Format [Intoduction to ASN.1](https://www.itu.int/en/ITU-T/asn1/Pages/introduction.aspx) is a Camel Frameworks’s data format implementation based on Bouncy Castle’s bcprov-jdk15on library and jASN.1’s java compiler for the formal notation used for describing data transmitted by telecommunications protocols, regardless of language implementation and physical representation of these data, whatever the application, whether complex or very simple. Messages can be unmarshalled (conversion to simple Java POJO(s)) to plain Java objects. By the help of Camel’s routing engine and data transformations you can then play with POJO(s) and apply customised formatting and call other Camel Component’s to convert and send messages to upstream systems.
7.1. ASN.1 Data Format Options
The ASN.1 File dataformat supports 3 options which are listed below.
Name | Default | Java Type | Description |
---|---|---|---|
usingIterator |
|
| If the asn1 file has more then one entry, the setting this option to true, allows to work with the splitter EIP, to split the data using an iterator in a streaming mode. |
clazzName |
| Name of class to use when unmarshalling | |
contentTypeHeader |
|
| Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc. |
7.2. Unmarshal
There are 3 different ways to unmarshal ASN.1 structured messages. (Usually binary files)
In this first example we unmarshal BER file payload to OutputStream and send it to mock endpoint.
from("direct:unmarshal").unmarshal(asn1).to("mock:unmarshal");
In the second example we unmarshal BER file payload to byte array using Split EIP. The reason for applying Split EIP is that usually each BER file or (ASN.1 structured file) contains multiple records to process and Split EIP helps us to get each record in a file as byte arrays which is actually ASN1Primitive’s instance (by the use of Bouncy Castle’s ASN.1 support in bcprov-jdk15on library) Byte arrays then may be converted to ASN1Primitive by the help of public static method in (ASN1Primitive.fromByteArray) In such example, note that you need to set usingIterator=true
from("direct:unmarshal").unmarshal(asn1).split(body(Iterator.class)).streaming().to("mock:unmarshal");
In the last example we unmarshal BER file payload to plain old Java Objects using Split EIP. The reason for applying Split EIP is already mentioned in the previous example. Please note and keep in mind that reason. In such example we also need to set the fully qualified name of the class or <YourObject>.class reference through data format. The important thing to note here is that your object should have been generated by jasn1 compiler which is a nice tool to generate java object representations of your ASN.1 structure. For the reference usage of jasn1 compiler see [JASN.1 Project Page](https://www.openmuc.org/asn1/) and please also see how the compiler is invoked with the help of maven’s exec plugin. For example, in this data format’s unit tests an example ASN.1 structure(TestSMSBerCdr.asn1) is added in src/test/resources/asn1_structure
. jasn1 compiler is invoked and java object’s representations are generated in ${basedir}/target/generated/src/test/java
The nice thing about this example, you will get POJO instance at the mock endpoint or at whatever your endpoint is.
from("direct:unmarshaldsl") .unmarshal() .asn1("org.apache.camel.dataformat.asn1.model.testsmscbercdr.SmsCdr") .split(body(Iterator.class)).streaming() .to("mock:unmarshaldsl");
7.3. Dependencies
To use ASN.1 data format in your camel routes you need to add a dependency on camel-asn1 which implements this data format.
If you use Maven you can just add the following to your pom.xml
, substituting the version number for the latest & greatest release (see the download page for the latest versions).
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-asn1</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>

Move
-
Put
9.4. Examples
These example are taken from tests:
from("atmos:foo/get?remotePath=/path").to("mock:test");
Here, this is a consumer example. remotePath
represents the path from where the data will be read and passes the camel exchange to regarding producer Underneath, this component uses atmos client API for this and every other operations.
from("direct:start") .to("atmos://get?remotePath=/dummy/dummy.txt") .to("mock:result");
Here, this a producer sample. remotePath
represents the path where the operations occur on ViPR object data service. In producers, operations(Get
,Del
, Move
,Put
) run on ViPR object data services and results are set on headers of camel exchange.
Regarding the operations, the following headers are set on camel exhange
DOWNLOADED_FILE, DOWNLOADED_FILES, UPLOADED_FILE, UPLOADED_FILES, FOUND_FILES, DELETED_PATH, MOVED_PATH;

Chapter 10. Atmosphere Websocket Component
Available as of Camel version 2.14
The atmosphere-websocket: component provides Websocket based endpoints for a servlet communicating with external clients over Websocket (as a servlet accepting websocket connections from external clients).
The component uses the SERVLET component and uses the Atmosphere library to support the Websocket transport in various Servlet containers (e..g., Jetty, Tomcat, …).
Unlike the Websocket component that starts the embedded Jetty server, this component uses the servlet provider of the container.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-atmosphere-websocket</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
10.1. Atmosphere-Websocket Options
The Atmosphere Websocket component supports 8 options which are listed below.
Name | Description | Default | Type |
---|---|---|---|
servletName (common) | Default name of servlet to use. The default name is CamelServlet. | String | |
httpRegistry (common) | To use a custom org.apache.camel.component.servlet.HttpRegistry. | HttpRegistry | |
attachmentMultipart Binding (common) | Whether to automatic bind multipart/form-data as attachments on the Camel Exchange. The options attachmentMultipartBinding=true and disableStreamCache=false cannot work together. Remove disableStreamCache to use AttachmentMultipartBinding. This is turn off by default as this may require servlet specific configuration to enable this when using Servlet’s. | false | boolean |
httpBinding (advanced) | To use a custom HttpBinding to control the mapping between Camel message and HttpClient. | HttpBinding | |
httpConfiguration (advanced) | To use the shared HttpConfiguration as base configuration. | HttpConfiguration | |
allowJavaSerialized Object (advanced) | Whether to allow java serialization when a request uses context-type=application/x-java-serialized-object. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk. | false | boolean |
headerFilterStrategy (filter) | To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
resolveProperty Placeholders (advanced) | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | boolean |
The Atmosphere Websocket endpoint is configured using URI syntax:
atmosphere-websocket:servicePath
with the following path and query parameters:
10.1.1. Path Parameters (1 parameters):
Name | Description | Default | Type |
---|---|---|---|
servicePath | Required Name of websocket endpoint | String |
10.1.2. Query Parameters (37 parameters):
Name | Description | Default | Type |
---|---|---|---|
chunked (common) | If this option is false the Servlet will disable the HTTP streaming and set the content-length header on the response | true | boolean |
disableStreamCache (common) | Determines whether or not the raw input stream from Servlet is cached or not (Camel will read the stream into a in memory/overflow to file, Stream caching) cache. By default Camel will cache the Servlet input stream to support reading it multiple times to ensure it Camel can retrieve all data from the stream. However you can set this option to true when you for example need to access the raw stream, such as streaming it directly to a file or other persistent store. DefaultHttpBinding will copy the request input stream into a stream cache and put it into message body if this option is false to support reading the stream multiple times. If you use Servlet to bridge/proxy an endpoint then consider enabling this option to improve performance, in case you do not need to read the message payload multiple times. The http/http4 producer will by default cache the response body stream. If setting this option to true, then the producers will not cache the response body stream but use the response stream as-is as the message body. | false | boolean |
headerFilterStrategy (common) | To use a custom HeaderFilterStrategy to filter header to and from Camel message. | HeaderFilterStrategy | |
sendToAll (common) | Whether to send to all (broadcast) or send to a single receiver. | false | boolean |
transferException (common) | If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a application/x-java-serialized-object content type. On the producer side the exception will be deserialized and thrown as is, instead of the HttpOperationFailedException. The caused exception is required to be serialized.
