The client side

There are several steps to perform to enable an application client to use the ORB.

Stub creation
For any distributed application, the client must know what object it is going to contact, and which method of this object it must call. Because the ORB is a general framework, you must give it general information about the method that you want to call.
ORB initialization
In a stand-alone Java™ application, the client must create an instance of the ORB.
Obtaining the remote object
Several methods exist by which the client can get a reference for the remote object.
Remote method invocation
The client holds a reference to the remote object that is an instance of the stub class. The next step is to call the method on that reference. The stub implements the Sample interface and therefore contains the message() method that the client has called.
Handling request retries
When a CORBA request results in a response of type org.omg.CORBA.SystemException, the IBM® ORB retries a request under certain conditions. You can control the number of retries and the time delay between retries by using system properties.
