Is there anybody using Geronimo and Camel?

[Antonio Fornié]

Hello!

Is there anybody using Geronimo and Camel? Is the integration easy? Is it working well?

Thank you very much.

just uncomment the following part in the $GERONIMO_HOME\var\activemq\conf\activemq.xml
    <!--
       Lets deploy some Enterprise Integration Patterns inside the ActiveMQ Message
       Broker. For more details see:
     
       http://activemq.apache.org/enterprise-integration-patterns.html
   
    <camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring">
     -->
     <!--</camelContext>-->

        <!-- You can use a <package> element for each root package to search for Java routes
        <package>org.foo.bar</package>
        -->

        <!-- You can use Spring XML syntax to define the routes here using the <route> element    -->
        <route>
            <from uri="activemq:example.A"/>
            <to uri="activemq:example.B"/>
        </route>
    </camelContext>

An you cab send a message from queue example.A to queue example.B

unfortunately Geronimo 2.2 is using ActiveMQ 5.3, but with the wrong namespaces for camel 2.0
and do not include activemq-all-5.3.0.jar only activemq-core-5.3.0.jar

example should be
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">

        <!-- You can use a <package> element for each root package to search for Java routes -->
        <package>org.foo.bar</package>

        <!-- You can use Spring XML syntax to define the routes here using the <route> element -->
        <route>
            <from uri="activemq:example.A"/>
            <to uri="activemq:example.B"/>
        </route>
    </camelContext>
and namespaces shpuld be replaced  activemq.apache.org/camel to camel.apache.org
http://cwiki.apache.org/confluence/display/CAMEL/Exception+-+BeanDefinitionStoreException
BeanDefinitionStoreException
If you use ActiveMQ 5.x that ships with Camel 1.x and you upgrade it to use Camel 2.0 you can get an exception while starting.
ERROR: java.lang.RuntimeException: Failed to execute start task. Reason: org.springframework.beans.factory.BeanDefinitionStoreException: Unrecognized xbean namespace mapping: http://activemq.apache.org/camel/schema/spring 
The reason is basically that the XML namespace changed in Camel 2.0 as explained below.
When Camel went from an activemq subproject to a top level apache project, they changed the URIs for their xml schemas to reflect this in Camel 2.0.
To fix this, in activemq.xml change all occurrences of:
http://activemq.apache.org/camel/schema/spring 
to
http://camel.apache.org/schema/spring 
and
http://activemq.apache.org/camel/schema/spring/camel-spring.xsd 
to
http://camel.apache.org/schema/spring/camel-spring.xsd 
These will probably occur in the xsi:schemaLocation attribute of the top level beans tag (both) and in the xmlns attribute in the camelContext element (just the first).

got error
 now in the FAILED state: abstractName="org.apache.geronimo.configs/activemq-bro
