V1.5 ORB Setting Timeout values

Question

Is it possible to set the timeout values used by the Java ORB?
I can�t find any information about it�
I know that in version 1.4.x was impossible.
I tried this with different values, but no success�
// transport read tcp timeout property, colon separated property
// with syntax <initial time to wait:max read giop header time to
// wait: max read message time to wait:backoff factor>
properties.put( "com.sun.CORBA.transport.ORBTCPReadTimeouts", "0:0:0:0");
orb = ORB.init(args, properties);I know the values are passed to the ORB properties (debug in eclipse), but the sockets created for the connections don�t use them�
Can some one please tell me how?
Ps: I know that JacORB offer this feature but I prefer continuing using the ORB offered by sun.
Thanks in advance!

Answer 1

I have had the code to do it in Java 1.4 for a couple years now. It is below with instructions. Last year I started porting to Java 5 and have been unable to find the solution until now. That is below as well.
(I am typing this from a printed copy so bear with me)
Java 1.4
// to use set the system property -
// com.sun.CORBA.connection.ORBSocketFactoryClass = Jre4SocketFactory
import com.sun.corba.se.connection.EndPointInfo;
import com.sun.corba.se.connection.GetEndPointInfoAgainException;
import com.sun.corba.se.internal.iiop.DefaultSocketFactory;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class Jre4SocketFactory
   extends DefaultSocketFactory
   public ServerSocket createServerSocket(String type, int port)
      throws IOException
      ServerSocket result = super.createServerSocket(type, port);
      result.setSoTimeout(3000);
      return result;
   public Socket createSocket(EndPointInfo epi)
      throws IOException, GetEndPointInfoAgainException
      Socket result = super.createSocket(epi);
      result.setSoTimeout(3000);
      return result;
Java 5
// to use set the system properties -
// com.sun.CORBA.transport.ORBSocketFactoryClass = Jre5SocketFactory
// com.sun.CORBA.transport.ORBConnectionSocketType = Socket
import com.sun.corba.se.transport.DefaultSocketFactoryImpl;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.Socket;
public class Jre5SocketFactory
   extends DefaultSocketFactoryImpl
   public ServerSocket createServerSocket(String type, InetSocketAddress in)
      throws IOException
      ServerSocket result = super.createServerSocket(type, in);
      result.setSoTimeout(3000);
      return result;
   public Socket createSocket(String type, InetSocketAddress in)
      throws IOException
      Socket result = super.createSocket(type, in);
      result.setSoTimeout(3000);
      return result;
}This is just how I did timeouts in corba. You can also implement encryption etc by using this method and wrapping up the socket. I figured out both of them by reading the source code out in com.sun.corba.se...etc. Both of the above are tested and work great in operational code.
