I think somehow it cannot locate the com interface, which has been registered in the registry.  Since the java console program works without any problem, I think the problem is related to the security settings of my com dlls.  I tried dcomcnfg and also setting the security permission of the com interface in the registry, but these also doesn't fix the problem.  My Tomcat is started without using a SecurityManager.

I think that if we were unable to locate the Jawin.dll you would get an
UnsatisfiedLinkError, so I think your are right that the Jawin part
seems okay.

But a wild guess: Is tomcat running as some kind of service, using
another user account than the one you are running the test-application
with? If this is the case, perhaps your COM-interface has only been
registered for your test user, and not system-wide and/or for the
tomcat-service user?

Hope this brings you a little further.
