There really are only two solutions: 1. Modify your application so that RequestFacade is not stored in the session object. You probably won't learn much from the stack trace, because that is tracing the replication process that failed, not the application code that stored the object. Look for a Serializable object in your app which has a reference to RequestFacade, perhaps in a member variable. Find a way not to use that reference, or not to store your containing object in the session. 2. Modify the Echo2 or Catalina source code so that RequestFacade is declared Serializable. I would be *very* cautious about doing that, because just declaring the Serializable interface doesn't mean that your object can be sensibly serialized -- it just means *you* think it can. As someone else suggested, read up on the serialization process before trying this. And in any case, this means forking a library module, which is usually a horrible idea. As others have said, this question is really more related to Tomcat than it is to Apache, so you will probably have better luck on the Tomcat forums. I'm hoping the above hints will give you a headstart on a Google search of those forums and/or a closer look at your application code.
