Hi,
This exception indicates that there is some problem in creation of EJBObject or remote object. Can you please increase the debug level of iAS, and provide KJS logs and also some more information about your application. It will be best if you can send me a copy of your application, I can deploy it here and will try to see the exact cause of the exception.
You can mail your application/test case on ias-help@sun.com or post it here.
Regards,
Sanjeev.
