RMI, SSL, and compression

Question

Hi,
I am trying to find an example of how to create a custom socket factory for RMI that does SSL and compression. Doing either separately is easy, but it seems that using SSL precludes the use of a custom socket as one would want for compression. Any suggestions or pointers would be appreciated.
Regards,
Neal

Thank you for the help. Sadly, I am still unable to wrap my brain around this one. I am hoping a concrete example will help out:
public class SecureServerSocketFactory implements java.rmi.server.RMIServerSocketFactory, java.io.Serializable
    /** Creates new SSLServerSocketFactory */
    public SecureServerSocketFactory()
     * Create a server socket on the specified port (port 0 indicates
     * an anonymous port).
     * @param  port the port number
     * @return the server socket on the specified port
     * @exception IOException if an I/O error occurs during server socket
     * creation
    public java.net.ServerSocket createServerSocket( int port )
        throws java.io.IOException
         SSLSocketFactory sssf = null;
        ServerSocketFactory ssf = null;
        ClassLoader cl = this.getClass().getClassLoader();
         try
            // set up key manager to do server authentication
            SSLContext ctx;
            KeyManagerFactory kmf;
            TrustManagerFactory tmf;
            KeyStore ks;
            char[] passphrase = "xxxxxxxxxxxxxx".toCharArray();
            ctx = SSLContext.getInstance( "TLS" );
            kmf = KeyManagerFactory.getInstance( "SunX509" );
            tmf = TrustManagerFactory.getInstance( "SunX509" );
            ks = KeyStore.getInstance( "JKS" );
            ks.load( new FileInputStream( SimpleLocator.getInstanceValue( "ServerKeystore") ), passphrase );
            kmf.init( ks, passphrase );
            tmf.init( ks );
            ctx.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );
            // this is w/o compression
            //ssf = ctx.getSocketFactory();
        catch( Exception e ) { e.printStackTrace(); }
        // need to put ejp's idea to practice here...
        // create a LZMACompressedSocket
        // put it into server mode?
        // wrap in SSL?
        return socket;
    }Any help you can provide would be appreciated.
On a related note, I do agree that compressing at this level likely will not help, but I want to try all solutions.
Thanks again for your help.
