JAXP/Xerces/Xalan application redeploy problem

[robjuh]

I have the Xerces and Xalan jars in my server's (default) lib directory, and when I do a clean server start everything works fine. However, there is some code that serializes XML to standard output, and when I do a hot re-deploy of my application, I get the appended stacktrace when this code is called. Any ideas out there?

BTW I get the same error if I put the jars in my ear file instead of in the server lib.

Have you checked your JRE lib/ext dir so it doesn't contain any XML libraries there (as they will get added to system classpath and may cause conflicts between redeployments) ?

[joel.rosi-schwartz]

I am having the exact same problem. I have checked lib/ext as suggested and that does not seem to be the problem. Has anyone figured out a solution?

Thanks,
Joel

It seems that your framework is using xerces,
try to put xerces.jar into your application's lib:
.war/WEB-INF/lib or move you framework jar into
default/deploy/lib dir.
