Oops, the XML snippets did not post: 1) Change the queue definitions in esb-quickstart-service.xml to use JBoss Messaging queues, e.g., | <server> | <loader-repository>jboss.messaging:loader=ScopedLoaderRepository | <loader-repository-config>java2ParentDelegation=false</loader-repository-config> | </loader-repository> | <mbean code="org.jboss.jms.server.destination.Queue" | name="jboss.messaging.destination:service=Queue,name=quickstart_helloworld_Request" | xmbean-dd="xmdesc/Queue-xmbean.xml"> | <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends> | </mbean> | 2) Copied the jboss-messaging-client.jar to JBoss-4.0.5.GA/client and added the following to the helloworld_embedded_reg/build.xml classpath | <fileset dir="${jbosshome.dir}/server/ps/deploy/jboss-aop-jdk50.deployer"> | <include name="jboss-aop-jdk50.jar"/> | </fileset> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993524#...
