Apparently we do use the context loader on the client side. So you will need to change it, however restore it immediately after obtaining the port: | ClassLoader oldLoader = Thread.currentThread().getContextClassLoader(); | | Foo foo; | | try | { | Thread.currentThread().setContextClassLoader(newLoader); | foo = FooService.getPort(); | } | finally | { | Thread.currentThread().setContextClassLoader(oldLoader); | } | | Make sure to remove the JMX classloader calls as well. If it still fails I would need to see the stack trace of the CNFE. -Jason View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4023261#...
