[jboss-user] Intra-EAR classloading problem

Hi, I have an EAR application containing a connector RAR and EJB3 JAR. My connector contains some classes which implement Serializable. Everything worked fine until I tried to put an instance of such a class in an ObjectMessage and then into a JMS queue from my EJB3 code, but now I get ClassCastExceptions when trying to get the instance back out. It seems that when the instance is deserialized and I try to cast it to the original type, the class literal of the type I am trying to cast it to and the runtime class of ObjectMessage.getObject() are loaded by different ClassLoaders, which I can confirm simply by printing them out. One of them has a URL pointing to the deployed EAR; the other has a null URL. I've tried defining a loader-repository for my EAR and using the class preload service, but neither had any effect on the problem. I've tried listing the types in question out in the loader-repository MBean using the JMX console, but only one InstanceN/CodeSource ever appears. The problem seems not to manifest itself after a fresh start of the server. I can only get CCEs after I re-publish the EAR from Eclipse. What can be done?
