J2EE 1.4 Compliance

Unable to properly deploy .war file when configured to be J2EE 1.4 compliant (configuration based on section 2.1 in http://docs.jboss.org/jbossas/whatsnew40/html/). When running as default config, it deploys fine but because of unified classloader, multiple .wars with conflicting class names are a problem. Hence the attempt using compilance config.

I've looked everywhere for a solution, or to see if someone else has come up against this, and I'm at a dead end. If I've missed the answer somewhere I apologise for wasting your time.

I get 2 main errors (I've attached the log file)
