I see the following error in the log (stdout or stderr actually) and notice that my stateful session bean did not survive the restart of the server. Error deserializing session: java.lang.NullPointerException Unfortunately, that error does very little to help me track it down. Can someone please give me some suggestions on how to track it down? Is there a way to get a more verbose error or even a stack trace to see where it's happening? I'm using Orion/1.1.24 on redhat linux 6.1 sun jdk1.2.2 Thank you, -joel shellman http://www.ants.com/
