Hi there, I have implemented a JCA 1.5 inbound-resourceadapter within my ear file. The resource adapter code is contained in a .rar file; the messagelistener-type interface is contained in a .jar file that is referenced from the manifest file of the rar. I have a MDB that implements the messagelistener-type, which is contained in another jar file. All of them are part of the ear. When I deploy and start the application everything works fine. If I then stop the MDB via the JMX console, when I try to start it again, I get a ClassNotFoundException for the messagelistener-type. Here is the stacktrace: [JBossMessageEndpointFactory] Starting failed jboss.j2ee:service=EJB,plugin=invoker,binding=message-inflow-driven-bean,jndiName=local/Solve3/RawProtocolRoutingMDBean@23247054 org.jboss.deployment.DeploymentException: Could not load messaging-type class biz.thelogicgroup.solve3.inputdriver.MessageRouting; - nested throwable: (java.lang.ClassNotFoundException: biz.thelogicgroup.solve3.inputdriver.MessageRouting) at org.jboss.deployment.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:39) at org.jboss.ejb.plugins.inflow.JBossMessageEndpointFactory.resolveMessageListener(JBossMessageEndpointFactory.java:312) I tried to reference the jar file that contains the messagelistener-type from the jar file that contains the MDB, but no difference. Any idea? Thanks, Michele View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4038520#...
