[jboss-user] [EJB 3.0] - Re: JBoss 5 deployment error

So that has solved your EJB3 problem. The other exception: anonymous wrote : Caused by: java.lang.ClassCastException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration | looks like a classloader issue. Remove the xml and xerces related jar files from your application package and deploy it. Those jars are already available in JBoss.
