Thanks for confirming this works!  I put a little documentation here:

Hello again.
I put xercesImpl.jar in the endorsed directory and it seems to be working. 
At least it survived a couple of redeployments.

Thanks

Hello.

I'm using Geronimo 2.1.4-SNAPSHOT downloaded today.
Xerces is the latest, 2.9.1 if I'm not mistaken.

I'm putting xercesImpl.jar in my WEB-INF/lib directory.

I'll try experimenting with the endorsed directory.

Greetings.

It's been a very long time since I dealt with this kind of problem but I have a faint memory that xml parsers are "endorsed" which basically means that classloading for them is completely messed up. I think you may need to put your copy of xerces in <geronimo-home>/ lib/endorsed. However I get endorsed and ext mixed up and it might be lib/ext. 

hope this helps more than it confuses.

Hello.

I'm trying to make OpenJPA and Xerces play along.
When I use my code as is without Xerces, everything works until I use new DocumentImpl(); - no surprise there.
When I add my xercesImpl.jar, sometimes it works (I suppose when the ClassLoader hasn't got poisoned) and then it stops when I redeploy: org.apache.openjpa.persistence.PersistenceException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

As a novice I see two options:
a) Use the same xerces as OpenJPA - I've been unsuccessful in locating it though. b) Shield the application somehow. I know that EARs have hidden- classes, but reading mailing lists it would see that it does not work with Xerces - why I'm not sure. 

How do I get around this issue?
