I have a project that uses an inbound resource connector and an message driven bean. I am trying to deploy these on jboss 4.2.3. The app has the following layout : | app.ear | lib/logic.jar | ejb.jar | ra.rar | The ra.rar just contains the ra.xml and the manifest Class-Path refers to lib/logic.jar. The ejb.jar also uses lib/logic.jar, and the definition of the MDB is within this jar. I sorted out the deployment issues around ordering, so I know the deployment order is not a problem. When I try to deploy, I get the following message : | 15:17:27,806 INFO [EJBContainer] STARTED EJB: com.my.mdb.WebAlertRAMDB ejbName: WebAlertRAMDB | 15:17:27,841 WARN [ServiceController] Problem starting service jboss.j2ee:ear=ear.ear,jar=ejb.jar,name=WebAlertRAMDB,service=EJB3 | org.jboss.deployment.DeploymentException: MessagingType 'com.my.api.WebAlertProcessor' not found in resource deployment jboss.jca:service=RARDeployment,name='ear.ear#ra.rar' | at org.jboss.resource.deployment.RARDeployment.createActivationSpec(RARDeployment.java:252) | at org.jboss.resource.deployment.RARDeployment.internalInvoke(RARDeployment.java:218) | at org.jboss.system.ServiceDynamicMBeanSupport.invoke(ServiceDynamicMBeanSupport.java:156) | Any clues as to what I am doing wrong? I tried putting the class it is looking for in the ra.rar but that didn't help. I also tried putting it in ejb.jar, again to no avail. And I have tried putting the logic.jar at the same level as the modules (ejb.jar and ra.rar). The jboss-app.xml has a custom class loader and the module order value of strict. Aside from that it is empty. Thanks, Edward View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213181#...
