I have an object that is used as a wrapper class for Castor called XMLUtil.
It is designed as a singleton object. When it first tries to instantiate
itself, it tries to instantiate a Castor object called Marshaller and gets
the following exception:
<Feb 4, 2003 8:29:26 AM EST> <Warning> <EJB> <010065> <MessageDrivenBean
threw an Exception in onMessage(). The exception was:

I have never seen this before. This object has been working fine for us
until now. This is the first time I have tried using it in WebLogic 7.0
versus 6.1, but that should not matter to Castor. Any help would greatly
appreciated.
