14.5. Using WSDL to configure JMS
14.5.1. JMS WSDL Extension Namespance
Example 14.5. JMS WSDL extension namespace
xmlns:jms="http://cxf.apache.org/transports/jms"
14.5.2. Basic JMS configuration
Overview
jms:address
element and its child, the jms:JMSNamingProperties
element. The jms:address
element’s attributes specify the information needed to identify the JMS broker and the destination. The jms:JMSNamingProperties
element specifies the Java properties used to connect to the JNDI service.
Specifying the JMS address
jms:address
element as the child of your service’s port
element. The jms:address
element used in WSDL is identical to the one used in the configuration file. Its attributes are listed in Table 14.2, “JMS endpoint attributes”.
Table 14.2. JMS endpoint attributes
Attribute | Description |
---|---|
destinationStyle | Specifies if the JMS destination is a JMS queue or a JMS topic. |
jndiConnectionFactoryName | Specifies the JNDI name bound to the JMS connection factory to use when connecting to the JMS destination. |
jmsDestinationName | Specifies the JMS name of the JMS destination to which requests are sent. |
jmsReplyDestinationName | Specifies the JMS name of the JMS destinations where replies are sent. This attribute allows you to use a user defined destination for replies. For more details see Section 14.6, “Using a Named Reply Destination”. |
jndiDestinationName | Specifies the JNDI name bound to the JMS destination to which requests are sent. |
jndiReplyDestinationName | Specifies the JNDI name bound to the JMS destinations where replies are sent. This attribute allows you to use a user defined destination for replies. For more details see Section 14.6, “Using a Named Reply Destination”. |
connectionUserName | Specifies the user name to use when connecting to a JMS broker. |
connectionPassword | Specifies the password to use when connecting to a JMS broker. |
jms:address
WSDL element uses a jms:JMSNamingProperties
child element to specify additional information needed to connect to a JNDI provider.
Specifying JNDI properties
jms:address
element has a child element, jms:JMSNamingProperties
, that allows you to specify the values used to populate the properties used when connecting to the JNDI provider. The jms:JMSNamingProperties
element has two attributes: name
and value
. name
specifies the name of the property to set. value
attribute specifies the value for the specified property. jms:JMSNamingProperties
element can also be used for specification of provider specific properties.

Example 14.6. JMS WSDL port specification
<service name="JMSService"> <port binding="tns:Greeter_SOAPBinding" name="SoapPort"> <jms:address jndiConnectionFactoryName="ConnectionFactory" jndiDestinationName="dynamicQueues/test.Celtix.jmstransport" > <jms:JMSNamingProperty name="java.naming.factory.initial" value="org.activemq.jndi.ActiveMQInitialContextFactory" /> <jms:JMSNamingProperty name="java.naming.provider.url" value="tcp://localhost:61616" /> </jms:address> </port> </service>
14.5.3. JMS client configuration
Overview
ByteMessage
or a JMS TextMessage
.
ByteMessage
the consumer endpoint uses a byte[] as the method for storing data into and retrieving data from the JMS message body. When messages are sent, the message data, including any formating information, is packaged into a byte[] and placed into the message body before it is placed on the wire. When messages are received, the consumer endpoint will attempt to unmarshall the data stored in the message body as if it were packed in a byte[].
TextMessage
, the consumer endpoint uses a string as the method for storing and retrieving data from the message body. When messages are sent, the message information, including any format-specific information, is converted into a string and placed into the JMS message body. When messages are received the consumer endpoint will attempt to unmarshall the data stored in the JMS message body as if it were packed into a string.
TextMessage
, the receiving JMS application will get a text message containing all of the SOAP envelope information.
Specifying the message type
jms:client
element. The jms:client
element is a child of the WSDL port
element and has one attribute:
Example
Example 14.7. WSDL for a JMS consumer endpoint
<service name="JMSService"> <port binding="tns:Greeter_SOAPBinding" name="SoapPort"> <jms:address jndiConnectionFactoryName="ConnectionFactory" jndiDestinationName="dynamicQueues/test.Celtix.jmstransport" > <jms:JMSNamingProperty name="java.naming.factory.initial" value="org.activemq.jndi.ActiveMQInitialContextFactory" /> <jms:JMSNamingProperty name="java.naming.provider.url" value="tcp://localhost:61616" /> </jms:address> <jms:client messageType="binary" /> </port> </service>
14.5.4. JMS provider configuration
Overview
- how messages are correlated
- the use of durable subscriptions
- if the service uses local JMS transactions
- the message selectors used by the endpoint
Specifying the configuration
jms:server
element. The jms:server
element is a child of the WSDL wsdl:port
element and has the following attributes:
Table 14.4. JMS provider endpoint WSDL extensions
Attribute | Description |
---|---|
useMessageIDAsCorrealationID | Specifies whether JMS will use the message ID to correlate messages. The default is false . |
durableSubscriberName | Specifies the name used to register a durable subscription. |
messageSelector | Specifies the string value of a message selector to use. For more information on the syntax used to specify message selectors, see the JMS 1.1 specification. |
transactional | Specifies whether the local JMS broker will create transactions around message processing. The default is false . [a] |
Example
Example 14.8. WSDL for a JMS provider endpoint
