2. JBI Components
2.1. servicemix-bean
Overview
The ServiceMix Bean component provides integration with beans (POJOs) with the JBI bus to make it
easy to use POJOs to process JBI message exchanges. Like in an Message Driven Bean in J2EE a POJO
will receive a message from the NMR and process it in any way it likes. Unlike in a JMS component
where the coding is already done the Bean component gives the developer the freedom to create any
type of message handling but it must be hand coded all the way.
Namespace and xbean.xml
The namespace URI for the servicemix-bean JBI component is http://servicemix.apache.org/
bean/1.0. This is an example of an xbean.xml file with a namespace definition with prefix bean.
<beans<beans xmlns:bean="http://servicemix.apache.org/bean/1.0">>
<bean:endpoint<bean:endpoint service="test:service" endpoint="endpoint" bean="#listenerBean"/>/>
<bean<bean id="listenerBean" class="org.apache.servicemix.bean.beans.ListenerBean"/>/>
</beans></beans></beans></beans>
Endpoint types
The servicemix-bean component only defines one endpoint, called bean:endpoint. It can be used
to receive and send message exchanges from/to the NMR.
Endpoint bean:endpoint
There are two ways to configure the bean endpoint. The first is using the fully qualified name of the
class and the second is by passing to the endpoint a reference to an existing bean.
Using a Java class
When definining a bean:endpoint specifying a Java class name, a new instance of this class will be
created for handling a single message exchange.
<beans<beans xmlns:bean="http://servicemix.apache.org/bean/1.0"
xmlns:my="urn:org:servicmix:docs:examples">>
<bean:endpoint<bean:endpoint service="my:service" endpoint="endpoint"
class="org.apache.servicemix.docs.bean.MyHandlerBean"/>/>
</beans></beans>
Using a spring bean
Alternative, a reference to an existing bean can be passed to the bean endpoint.
