Hi
I am currently porting an application from WebSphere 5.1 to JBoss 4.0, but am having
problems getting it deployed on JBoss. The application uses EJB's and a great deal of
XML parsing, and has been working for many years already on WebSphere.
The application is packed in an ear, with a war and several jar within it.
When i try to deploy I get the following error:
| 09:59:57,390 ERROR [Digester] Digester.getParser:

However, when I remove the xmlparserv2.jar from the ear, the error changes to:

Does anybody have an idea on how I can fix this? I've been at it for a couple of days
and starting to get a little fed up...
