RMI in JDK6 problem

[Suhas Bilaye]

Hi,

I am trying to develop a distributed application using java RMI in jdk6. I have studied the java 6 RMI release notes at http://java.sun.com/javase/6/docs/technotes/guides/rmi/relnotes.html . In the notes it says,

An existing application can be deployed to use dynamically generated stub classes unconditionally (that is, whether or not pregenerated stub classes exist) by setting the system property java.rmi.server.ignoreStubClasses to "true". If this property is set to "true", pregenerated stub classes are never used.

which is with respect to java 6.

I have following server code which throws a StubNotFoundException if I remove the stub from the directory where it is supposed to be and I run the code by setting the java.rmi.server.ignoreStubClasses system property to true.(As explained in the notes)

  package com.rmi.test.local.server;

import java.util.List;
import java.net.MalformedURLException;
import java.rmi.AlreadyBoundException;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.ArrayList;

import com.rmi.test.remote.interfaces.GreetingProvider;

public class GreetingServer implements GreetingProvider{

	protected GreetingServer(){
		
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		System.setProperty("java.security.policy", "E:/Research_WS/RMITEST2/java.security.policy");
		System.out.println(System.getProperty("java.security.policy"));
		System.out.println(System.getProperty("java.rmi.server.ignoreStubClasses"));
		
		System.setProperty("java.rmi.server.ignoreStubClasses", "true");
		System.out.println(System.getProperty("java.rmi.server.ignoreStubClasses"));
		
		if (System.getSecurityManager() == null)
            System.setSecurityManager ( new RMISecurityManager() );
		
		try {
			GreetingProvider server = new GreetingServer();
			GreetingProvider stub = (GreetingProvider) 
				UnicastRemoteObject.exportObject(server);
			
			Naming.bind("GreetingServer", stub);
			System.out.println("service bound");
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (AlreadyBoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}


	}

	@Override
	public String getGreeting() {
		return "Hello World";
	}

}
  

The getGreeting method is in the GreetingProvider interface which extends Remote interface.
Why are the stubs not generated at runtime? Can anyone throw some light at this?
