Did you change your bean recently? It sounds like your remotes are out of date. Ensure you remotes on the client side match up properly. Also ensure any Serialiazable classes you pass via method calls are not updated in only the client of server. This error normally happens when you either try to cast the wrong object (I.e. in Collections this can happen easily if you are not careful) and serialized objects (when the new class doesn't match up to the old one). These will compile fine, but break during runtime.
Without any other information, this is all I can add. Hope this helps.

My question is how do i go about debugging this? Is it possible to get access to the generated .java files?
