Can any body tell me why this exception is encountered in Weblogic.I have seen this many time while running EJBs.What I need is a Idea or some words describing what it means and when can u face this.
Usually this means you are attempting to transfer an object over the network that is not serializable. Check all your value objects.
Wouldn't that cause a marshalling error instead of a Unmarshalling error?
Please provide more information related to your case.
