[omniORB] JavaIDL and OmniORB

[James Dempsey]

I'm not having any problem getting a JavaIDL client to talk to an
OmniORB server.
My command line looks like:

java EchoClient -ORBInitialPort 1050

I've started OmniNames using:

omninames -start 1050

I had the same problem this week-end. I guess it's a bug in Sun's
Java. Try
to use the ior to connect to your server object and you'll see that it
works.

Hi Everybody:

I am trying to use OmniOrb as Server and JavaIDL as Client. Looking at
the
archive of this mailing list it seem it is possible.
Unfortunately up to now I have been unsuccessful.

I always get the same errors from the java client. I am trying to
comunicate
with the echo server example.

)
        at NameClientList.main(NameClientList.java:22)

This is the java code at line 22 that generate the error:

orb.resolve_initial_references("NameService")

I know the setting for the port are correct since if I change them I
get a
CORBA.COMM_FAILURE error.

Any help would be greatly appreciated.

This is the java code.

service.

    void t(String args[]){

                props.put("org.omg.CORBA.ORBInitialPort", "2090");


                ORB orb = ORB.init(args, props);

                System.err.println("Searching For the NamingService");

            // Call the Hello server object and print results
            String hello = helloRef.echoString("Alessandro");
            System.out.println(hello);

        } catch(Exception e) {

            e.printStackTrace(System.out);

        }
    }
