Not that I'm aware of but how would I know? I have Struts 2 and Hibernate and all there dependent jars but nothing else that looks like it's an XML parser. >regarding your reloading problem I have another idea.

Again, everything works when I launch Tomcat fresh or restart it from within Eclipse. I only get the error when Tomcat attempts to reload the application. Here seems to be the core issue: Caused by: java.lang.ClassCastException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration Any ideas on how to figure out what is going on?
