Hello.

This is a known bug in src/jacorb/orb/ORB.java (although it seems I 
have not provided a fix). To fix it, please edit the source code of
ORB.java and change l.180 (or l. 181, method _getConnection())
which says

	if( retries == 0 )

to

	if( retries < 0 )

After recompiling, you should get a org.omg.CORBA.COMM_FAILURE 
exception instead of a NullPointer - which is correct here.
Judging from you stack trace below, your application does need 
the name  server as it actively tries to bind to it, no hidden 
ORB activity here ;-).

Regards, Gerald Brose.
