NullPointer Exception in save()

I have the exact same problem as the previous post.  My stacktrace yields the same information but here is the log error:

DEBUG - IDBroker thread was started.

Any ideas on why jdbc Driver might be wrong?  I use this driver daily without problems.  I am using MySQL with the com.mysql.jdbc.Driver 3.0.
 
Thanks,
