[jboss-user] [EJB 3.0] - Sudden unexplainable problem w/ persistence unit

[tsar_bomba]

I really don't know how to explain what's happening here.  I have a straight-forward enterprise app that I've been deploying to JBoss 4.0.5 all day...and have not had a problem until now.

The error is complaining about the persistence unit in the .ear - but that file hasn't changed in *months* - I just checked the svn history on it.

I can't deploy now and I don't know why...here's the exception I'm getting:

I don't understand, what's NULL??  Clearly there's another problem but there's no indication as to what it might be.  I've tried restarting jboss, I've even restarted my PC...I just can't deploy this app anymore.

Could someone please provide some insight on this?

Thanks!
