[omniORB] about make a servant both CORBA client and CORBA server

[zhang ji]

Hi Luke,

Thanks for your help. Yes it can use only one ORB. I
am sorry for one error where I declare the orb twice!

The CORBA specification said :"The ORB_init operation
may be called any number of times and shall return the
same ORB reference when the same ORBid string is
passed." So if we call more than one ORB_init(), it
will return the same orb.That is why you say it should
use only one ORB? And that is why when I
shutdown/destroy orb2 the program will crash.

Thanks,
Shifeng
