additional question: relies tomcat itself on the libs in CATALINA_HOME/common/lib ?
if not, it could be a good idea to just remove all xml-related libraries from there and (redundantly) including them in WEB-INF/lib of the projects to gain some sort of control. - just a thought and i didn't have a closer look at the class-loading mechanism. are there any best practices for that one might follow?
