Auto-discovery is a mechanism that enables you to dynamically add components to your Fuse Mediation Router application. The component URI prefix is used as a key to load components on demand. For example, if Fuse Mediation Router encounters the endpoint URI, activemq://MyQName, and the ActiveMQ endpoint is not yet loaded, Fuse Mediation Router searches for the component identified by the activemq prefix and dynamically loads the component.

Before configuring auto-discovery, you must ensure that your custom component classes are accessible from your current classpath. Typically, you bundle the custom component classes into a JAR file, and add the JAR file to your classpath.

To enable auto-discovery of your component, create a Java properties file named after the component prefix, component-prefix, and store that file in the following location:

/META-INF/services/org/apache/camel/component/component-prefix

The component-prefix properties file must contain the following property setting:

class=component-class-name

Where component-class-name is the fully-qualified name of your custom component class. You can also define additional system property settings in this file.

For example, you can enable auto-discovery for the Fuse Mediation Router FTP component by creating the following Java properties file:

/META-INF/services/org/apache/camel/component/ftp

Which contains the following Java property setting:

class=org.apache.camel.component.file.remote.RemoteFileComponent
