[jboss-user] [Beginners Corner] - InvalidClassException when connecting standalone client to J

[puzz]

Hi all,

We are using JBoss 4 as application server.
We have a standalone client connecting to the server and this has worked fine up until a few days ago.
Suddenly we keep getting exceptions.
See below stacktrace.
Any help with this much appreciated! I've tried google but without any luck.
