Hi,
I am not sure if this question is for this forum, just trying my luck.

JBoss and JProbe are running on the same machine with WinNT as OS. My application(EJBs) on JBoss runs fine without JProbe. When I run JProbe Profiler, the console window comes up and routine JBoss startup messages are printed, but then this exception comes up :
