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?
