Hello,
We have migrated from JBOSS4 to JBOSS7.
The applciation run, there is only some web services are failing with the following error :
org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

If replcace the jboss7 xalan lib by xalan library 2.7.0 from xalan, that run well. But i think, it's not the best way to fixe my issue.

Then I try to embaded the lib in the applciation war and i added a jboss-deployment.xml in to exclude the org.apache/xalan lib from jboss, but that does not work. please can you help me ?
