[omniORB] EndPointNoListen problems, IOR problems etc.

Mon Apr 12 11:56:37 BST 2004

Can anyone help me out on this?  I'm still stuck on this.  I can get 
omniORB to give the right IP address in it's IOR strings, but once I add 
those lines to my cfg the example server breaks.

It almost seems like the object is being deleted, as is the naming context 
I create.  Is there something going on that causes the root POA to delete 
the objects once I create them?  Please help.

Mike
