I'm trying to call an external RMI service from my custom LoginModule. When I try it, I get this:

This happens at the point where my LoginModule's code wants to do a Naming.lookup() on an RMI URL. I can't get an RMI classLoader.

I'm running JBoss 2.4.4, from the December 29 binary releases. I get basically the same result using the Jetty, Catalina, and Tomcat bundles.

Is there a JBoss configuration tweak or JBoss usage pattern which will allow my LoginModule code to invoke an external RMI service?

I'm aware that I *could* implement the service I need as an MBean, thus avoiding the need to invoke via RMI. So I don't need a sermon. I need either "No. Can't be done." or "Yes. Here's how to do it...".

Thanks
