Am i missing something in Jboss Messaging configuration? Or it has something to do with my listener configured inside web application? When i first send same object message using jsp/servlet, everything works fine. After this subsequent sending and receiving from plain java class works. But when i first send it using plain java class, message listener throws following exception "java.lang.RuntimeException: No ClassLoaders found for: <fully classified custom class name> Please reply, i got stuck with this issue.
