    Porblems in invoking remote CORBA server object from EJB

    3004

      Hi, all

      Has anyone invoke a remote CORBA servant from a weblogic component running ionside
      weblogic server 8.1?

      I have a simmple EJB which is using a helper class to initialize the orba, and
      invoke a remote CORBA
      servant developed using JDK 1.4 and RMI/IIOP. The helper class is running fine
      in standalone java
      client, but some how it failed when I run it from weblogic server.

      The error message is:
      ERROR: Caught NamingContextPackage.NotFound exception: IDL:omg.org/CosNaming/Nam
      ingContext/NotFound:1.0

      The sample code to do initialization is as follows:
      =====================================================
      // Get the root naming context.
      org.omg.CORBA.Object objRef;
      try {
      objRef = orb.resolve_initial_references("NameService");
      }
      catch (org.omg.CORBA.ORBPackage.InvalidName e) {
      System.err.println("ERROR: Caught InvalidName exception: " + e.getMessage());
      return null;
      }

      NamingContext ncRef = NamingContextHelper.narrow(objRef);
      System.out.println("Resolved ORB nameserver...");

      // Resolve the OSS object reference in Naming service.
      NameComponent nc = new NameComponent(services, "");
      NameComponent path[] = {
      nc};

      System.out.println("Attempting to get factory (" + services + ")...");


      try {
      ossFactory = OSSServerHelper.narrow(ncRef.resolve(path));
      }
      catch (org.omg.CosNaming.NamingContextPackage.InvalidName e) {
      System.err.println("ERROR: Caught InvalidName exception: " + e.getMessage());
      return null;
      }
      catch (org.omg.CosNaming.NamingContextPackage.NotFound e) {
      System.err.println(
      "ERROR: Caught NamingContextPackage.NotFound exception: " +
      e.getMessage());
      return null;
      }
      catch (org.omg.CosNaming.NamingContextPackage.CannotProceed e) {
      System.err.println("ERROR: Caught CannotProceed exception: " +
      e.getMessage());
      return null;
      }
      ================================================

      Anyone has any suggestion? Thanks very much, zzou

          You missed out how you initialized the ORB. If you just called
          ORB.init() then this is the problem as this will go to the local WLS
          NameService. Also there were some bugs fixed in this area in both SP1
          and SP2, so its possible that you are running into one of those. The way that will probably work in the version of WLS that you have is by doing:

          ORB.init().string_to_object("corbaloc:iiop:foreignHost:foreignPort/NameService");

                You missed out how you initialized the ORB. If you just called

                Hi, all

                Has anyone invoke a remote CORBA servant from a weblogic component
                running ionside
                weblogic server 8.1?

                I have a simmple EJB which is using a helper class to initialize the
                orba, and
                invoke a remote CORBA
                servant developed using JDK 1.4 and RMI/IIOP. The helper class is
                running
                fine
                in standalone java
                client, but some how it failed when I run it from weblogic server.

                The error message is:

                  It looks to me that it works fine from the stack trace,just the ior leads the broker
                  to non-exitent naming server.

                    Dear All,
                    I have solved this case by use Visibroker 6 lib with jdk1.4. However,
                    using weblogic.jar instead of wlclient.jar. Hope this can help all.

                    It looks to me that it works fine from the stack trace,just the ior leads
                    the broker
                    to non-exitent naming server.

                    You missed out how you initialized the ORB. If you just called
                    ORB.init() then this is the problem as this will go to the local
                    WLS
                    NameService. Also there were some bugs fixed in this area in both
                    SP1
                    and SP2, so its possible that you are running into one of those.
                    The
                    way that will probably work in the version of WLS that you have is
                    by
                    doing:
                    ORB.init().string_to_object("corbaloc:iiop:foreignHost:foreignPort/NameSe

                    Hi, all

                    Has anyone invoke a remote CORBA servant from a weblogic component
                    running ionside
                    weblogic server 8.1?

                    I have a simmple EJB which is using a helper class to initialize
                    the
                    orba, and
                    invoke a remote CORBA
                    servant developed using JDK 1.4 and RMI/IIOP. The helper class
                    is
                    running
                    fine
                    in standalone java
                    client, but some how it failed when I run it from weblogic server.

                    The error message is:

                      Hi,
                      I am using Weblogic8.1sp2. I am trying to corba object. ORB initializing happening but not orbinitializser is not executed.
                      We are using PortableInterceptors. So OrbInitlizer class we are implementing same thing i have set in the properties of ORB.init method.
                      But some how it is not executing that class while intializing. That getting below exception:
                      org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No


                      I dont know how to go about it.

                      Pls suggest to to procede.
                      I am giving below code snippet of my java program:

                      props.setProperty("org.omg.PortableInterceptor.ORBInitializerClass.com.abc.abc1.abc2.access.abc3.Abc3ValidationService", "");

                      props.put("org.omg.CORBA.ORBSingletonClass", "com.sun.corba.se.internal.iiop.ORB");

                      orb.init(args,props);
