Hi,

I have a corba client-server application. The ports on both the machines are not open abruptly. Only certain ports are open. Now when I make a corba request from machine A (client) to machine B (server), its giving me following error:

I ran the client 3 times in the machine and all the 3 times I got the same error. Please have a look at the port number (40130), it was same in all the 3 request.

Now after this, I changed the scenario that is I made A as server and B as client and sent a corba request from B to A. At this point of time I am getting following error:

I ran the client 3 times in the machine and all the 3 times I got the same error. Please have a look at the port number (46379), it was same in all the 3 request.

For orbd I use 2050 port.

This part of the code is working fine:
NamingContext namingContext = NamingContextHelper.narrow(
orb.resolve_initial_references("NameService"));
NameComponent[] nc = { new NameComponent("HelloServer", "") };

//resolve HelloServant and invoke sayHello()
Hello helloRef = HelloHelper.narrow(namingContext.resolve(nc));

After this when I make actual call to the corba method, its failing and giving the above mentioned errors.

How do I resolve this?


Regards,
Rajeev
