Hi,

I am trying to communicate between a Java 1.3 corba server written in
OrbixWeb3.2 and a Visigenic 3.4 corba Java 1.4 client. I am using
Naming service IOR to achieve this.

I am able to get the inter ORB comm to work only when I DO
NOTexplicitly set the
org.omg.CORBA.ORBClass                     to     
com.visigenic.vbroker.orb.ORB
and org.omg.CORBA.ORBSingletonClass to com.visigenic.vbroker.orb.ORB

I want the inter-ORB to work when I set the above ORB classes and make
the
necessary changes to the Client code. Any suggestions on making this
work
(to the 2nd code below) is really appreciated.


The following code works perfectly fine  with the following command
======================================================
/usr/j2se/bin/java -Xbootclasspath:/usr/j2se/jre/lib/rt.jar -classpath

/usr/j2se/lib/swingall.jar:/usr/j2se/jre/lib/rt.jar
Demos.namesStaff.Client

Note: Here the ORB used is a Java 1.4 implementation.
