      • remoteToCorba

        public static Object remoteToCorba​(java.rmi.Remote remoteObj,
                                           ORB orb)
                                    throws javax.naming.ConfigurationException
        Returns the CORBA object reference associated with a Remote object by using the javax.rmi.CORBA package.

        This method effective does the following:

         java.lang.Object stub;
         try {
             stub = PortableRemoteObject.toStub(remoteObj);
         } catch (Exception e) {
             throw new ConfigurationException("Object not exported or not found");
         }
         if (!(stub instanceof javax.rmi.CORBA.Stub)) {
             return null; // JRMP impl or JRMP stub
         }
         try {
             ((javax.rmi.CORBA.Stub)stub).connect(orb);  // try to connect IIOP stub
         } catch (RemoteException e) {
             // ignore 'already connected' error
         }
         return (javax.rmi.CORBA.Stub)stub;
         
        Parameters:
        remoteObj - The non-null remote object for
        orb - The non-null ORB to connect the remote object to
        Returns:
        The CORBA Object for remoteObj; null if remoteObj is a JRMP implementation or JRMP stub.
        Throws:
        javax.naming.ConfigurationException - The CORBA Object cannot be obtained because of configuration problems.
      • getOrb

        public static ORB getOrb​(java.lang.String server,
                                 int port,
                                 java.util.Hashtable<?,​?> env)
        Get ORB using given server and port number, and properties from environment.
        Parameters:
        server - Possibly null server; if null means use default; For applet, it is the applet host; for app, it is localhost.
        port - Port number, -1 means default port
        env - Possibly null environment. Contains environment properties. Could contain ORB itself; or applet used for initializing ORB. Use all String properties from env for initializing ORB
        Returns:
        A non-null ORB.

                                                    java.io.UnsupportedEncodingException
        Decode a URI string (according to RFC 2396). Three-character sequences '%xy', where 'xy' is the two-digit hexadecimal representation of the lower 8-bits of a character, are decoded into the character itself. The string is subsequently converted using the specified encoding
        Throws:
        java.net.MalformedURLException
        java.io.UnsupportedEncodingException
