I think you can fix this problem by making your class serializable. And it is not strange if this happens in WebLogic but not in Tomcat.
According to the Exception Stack, I guess the cause of this Exception is: (1)You putted some object into the session. (2)You are trying to retrieve it from the session lately. (3)weblogic.servlet.internal.session.SessionData.getAttribute is called, and it calls: (4)weblogic.common.internal.PassivationUtils.copy method, and it calls: (5)weblogic.common.internal.PassivationUtils.toByteArray, and it calls: (6)java.io.ObjectOutputStream.writeObject method. It try to write your object into a stream, but your object is not serializable. So the exception is thrown. This looks like happening under the implement code of Session management of WebLogic. Tomcat don't thrown this Exception, maybe because when it get object from the session, it don't try to make a copy. But, In my opinion, putting an unserializable object into the session could cause a potential problem, because sometimes the session data need to be dumped into hard disk file, or to be transferred between app servers. If your object is not Serializable, these operation will fail. 2010/11/17 Struts Newbie <stefaan.som...@gmail.com>: > > We have a portlet running within the Liferay-container on WebLogic, that is >
