This is the default configuration behavior. Add a <loader-repository> tag to your deployment to isolate the classloaders.
I can't seem to find the right place for this. Can you confirm what you mean by add a <loader-repository> tag to my deployment? I've found some references to this online, but nothing that will work for me. Thanks in advance!
Depending on your package type, jboss.xml, jboss-app.xml, etc. The DTDs are included with your JBoss distro.
