[jdom-interest] XML Registry Definition

[Mike Vesey]

Hello all,
I'm new to the list and jdom and hoping I can get a little help.
I'm using BEA's Weblogic Portal Server on solaris and am having some
difficulty with the XML Registry.  It seems that Portal server already has a
XML Registry entry in the config.xml and it is causing my app to bust.  My
app works fine on a server with now XML Registry defined in config.xml.

Here is a message I sent to Jason Hunter, he recommended I forward to this
list for a more prompt response.
Thanks for any help you can provide.
Mike

I have a program I've written

fact

email
