Clever. They're using the security Access Controller to set the context
classloader to the servlet class loader. Every class load will trigger a
SecurityManager call that runs this special Privilege that sets the
classloader. It will work with any Java2 system BTW.
Thanks for the info, it fixed my problem.

If you're running Tomcat under JDK 1.2.2+, look at the Tomcat link
on the jBoss web page. You can ignore most of it, since it's intended for
people running jBoss and Tomcat in the same VM, but there is a section on
adding a JDK 1.2 request interceptor to Tomcat's server.xml that you
should follow. This will fix your ClassLoader problems.
