[Java 1.4.2] Rmi over SSL : bind/rebind hangs

Question

Hello everybody,
I am trying to test client/server communication with RMI over an SSL layer, as explained here .
Here is my server class :
package rmitest.server;
import java.rmi.registry.*;
import java.rmi.*;
import rmitest.client.RMISSLClientSocketFactory;
import java.rmi.server.RMIClientSocketFactory;
import java.rmi.server.RMIServerSocketFactory;
import java.rmi.registry.LocateRegistry;
import java.rmi.server.*;
import java.io.IOException;
public class Hello extends UnicastRemoteObject implements HelloInterface
    public Hello(RMIClientSocketFactory csf, RMIServerSocketFactory ssf) throws RemoteException
        //super();
        super(1099, csf, ssf);
        System.out.println("Initialisation de Hello OK.");
    public int sayHello()
        try {
        System.out.println("Hello, World !");
        return 0;
        catch (Exception e)
            e.printStackTrace();
            return 1;
    public static void main(String[] args)
        try
            System.setSecurityManager(new RMISecurityManager());
            RMIClientSocketFactory csf = new RMISSLClientSocketFactory();
            RMIServerSocketFactory ssf = new RMISSLServerSocketFactory();
            HelloInterface myHello = new Hello(csf, ssf);
            Registry reg = LocateRegistry.getRegistry("lat203", 1099, csf);
            reg.rebind("HelloInterface", myHello);
            System.out.println("The server is ready.");
        catch (RemoteException e)
            e.printStackTrace();
        catch (Exception e)
            e.printStackTrace();
}My problem is, the program hangs in the rebind(...) instruction. Would anybody have a clue ?
Here is the stack just before it hangs :
{codeThread [main] (Stepping)
UnicastRef2(UnicastRef).newCall(RemoteObject, Operation[], int, long) line: 313
RegistryImpl_Stub.rebind(String, Remote) line: not available
Hello.main(String[]) line: 56
Thread [Thread-1] (Running) }Thank you by advance.

Answer 1

Ok I settled that in the client socket factory. Here is what it looks like :
package com.infotel.rmitest.client;
import java.io.*;
import java.net.*;
import java.rmi.server.*;
import javax.net.ssl.*;
import sun.security.util.Debug;
public class RMISSLClientSocketFactory
    implements RMIClientSocketFactory, Serializable {
    public Socket createSocket(String host, int port)
    throws IOException
        SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault();
        SSLSocket socket = (SSLSocket)factory.createSocket(host, port);
        String[] strtab = {"TLSv1", "SSLv3"};
        socket.setEnabledProtocols(strtab);
        System.out.println("---> before handshake");
        socket.startHandshake();
        System.out.println("---> after handshake.");
        return socket;
    public int hashCode()
        return getClass().hashCode();
    public boolean equals(Object obj)
        if (obj == this)
            return true;
        else if (obj == null || getClass() != obj.getClass())
            return false;
        return true;
}I haven't modified my Server socket factory.
The client still hangs but the messages are different as I have removed the SSLv2ClientHello :

(lots of trusted certificates...)

done seeding SecureRandom
---> before handshake

Now my server output (I don't give the verbose certificates):
