already many thnks for answering. I've tried enabling-disabling optimistic-serialization but without any success. It's strange that WebLogic tries to serialize the Struts-action itself. So I'm still banging the wall, and it starts to give me a serious headache. This is the stack-trace I've got for the moment : java.io.NotSerializableException: java.lang.Object at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1156) at
