Access permission exceptions when calling RMI from within Tomcat servlet.

[Johnny Tolliver <jx...@ornl.gov>]

I have a simple RMI server that I need a Tomcat servlet to access.

A very simple command-line app accesses the RMI server just fine with the
following code:

registry = LocateRegistry.getRegistry (host);
xxx = (XXX) registry.lookup (name);

But when I move the same code into my servlet I get strange access permission
exceptions. The exception traces back to a "caused by" access denied having to
do with java.util.logging.LoggingPermission, which eventually leads back to
some JULI code.

Any ideas what's going on here? Thanks. The full stacktrace is here:

(Actually, the RMI registry call is made from a thread that was launched by a
servlet, but the point is that it is in Java code launched by and running
under the control of Tomcat.)
