User development, A new message was posted in the thread "JMS Consumer (servlet) can not resolve class of the object passed in ObjectMessage": http://community.jboss.org/message/519304#519304 Author : Ola Hamfors Profile : http://community.jboss.org/people/hamfors Message: -------------------------------------------------------------- I have the same problem but in a sligthly different setting. I have a ear (The ear defines a loader-repository in jboss-app.xml) with 2 nested jar files (ejbs) and one of the jar files has a MDB that recieves object messages send from a class in the other jar file i.e within the same ear. I'm using jboss-eap-5.0.0.GA. But I guess I should report this in another channel. Your class loader test with the change of classloaders before obtaining the objectmessage solved the problem for me too.. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/519304#519304
