Method Detail

remoteToCorba

public static Object remoteToCorba(Remote remoteObj,
                                   ORB orb)
                            throws ClassNotFoundException,
                                   ConfigurationException

Returns the CORBA object reference associated with a Remote object by using the javax.rmi.CORBA package.

Use reflection to avoid hard dependencies on 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:

ClassNotFoundException - The RMI-IIOP package is not available

ConfigurationException - The CORBA Object cannot be obtained because of configuration problems.

getOrb

public static ORB getOrb(String server,
                         int port,
                         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.
