I've been working along for several months on an EJB3 project in an archive I called tie.jar when I went to refactored a few class names. Now I suddenly get this error:

How do I even go about diagnosing this error?

The tie.jar file deployed fine before the name changes and now even if I change the names back the deploy fails. If I use an old copy of the tie.jar in a JBoss server that the new deploy failed on the new jar fails until I stop the server, clear the working files, and restart it.

My other EJB3 jar files are unaffected by the problem leading me to believe that this is a problem in my code not in the server configuration.

I can't find where my code is causing the SchemaTypeCreator to fail out because there is no trace message about my class file structure at all. None of the classes from the tie.jar ... named tie.ClassName show up... how should I know which classes of mine are causing this issue? I suspect it is a change I made in the classes I refactored but I can't change the names back and get a working copy.

Any ideas? Where do I even start?
