Thanks again for all your suggestions and help...I am able to narrow the problem down to org.jboss.remoting.InvokeLocator. Apparently when I try to instantiate this class, I will get a NoClassDefFound exception (without indicating what class is missing). I am able to create the org.jboss.logging.Logger object within my application but not the InvokeLocator. What could be some of the dependencies for InvokeLocator other than jboss Logger?
