I wanted to use RMI over IIOP in my project. To get hands on, i have written a sample program
using j2sdk1.4.2_09 and followed the same steps listed at
http://java.sun.com/j2se/1.4.2/docs/guide/idl/orbd.html to start the server.

It is working fine if i don't initialize the ORB multiple times (i.e Only once.). But When i tried
to intialize ORB multiple times it is throwing the following exception at the time of registering
the server through servertool.

ErrorLog:
