Question

I have implement the following code to create a SSL server socket.

    public void createConnection(){
     port =8888;
    listen = true;
            isSvrRuning = true;
            try {


                String KEYSTORE = Config.KEYSTORE_FILE;
                // String KEYSTORE = "/u04/app/ato/data/keystore/ATradSvrKeyStore";
                char[] KEYSTOREPW = "abcd".toCharArray();
                char[] KEYPW = "abcd".toCharArray();
                com.sun.net.ssl.TrustManagerFactory tmf;

                boolean requireClientAuthentication;

                java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
                java.security.KeyStore keystore = java.security.KeyStore.getInstance(
                        "JKS");
                keystore.load(new FileInputStream(KEYSTORE), KEYSTOREPW);

                com.sun.net.ssl.KeyManagerFactory kmf = com.sun.net.ssl.KeyManagerFactory.getInstance("SunX509");
                kmf.init(keystore, KEYPW);

                com.sun.net.ssl.SSLContext sslc = com.sun.net.ssl.SSLContext.getInstance("SSLv3");
                tmf = com.sun.net.ssl.TrustManagerFactory.getInstance("sunx509");
                tmf.init(keystore);

                sslc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
                SSLServerSocketFactory ssf = sslc.getServerSocketFactory();

                ssocket = (SSLServerSocket) ssf.createServerSocket();
                try {
                    ssocket.setReuseAddress(true);
                } catch (SocketException ex) {
                    loggerSvr.log(Level.SEVERE, "SocketException in setting timeout for serverSocket.");
                    ex.printStackTrace();
                }
                ssocket.bind(new InetSocketAddress(port));
                ssocket.setNeedClientAuth(true);
                while (listen) {
                    //wait for client to connect//
                    socket = ssocket.accept();
        // here goes the code which need to handle a new connection
    }

}catch(){
//there are several catch blocks to catch all checked exceptions
}
}

If there is a problem or exception in the above socket I close the socket and recreate another server socket by calling above method. But the problem is some time I cannot recreate the server socket using the same port. It gives following error when I am trying to do it.

Server socket allocation error for the specific port

I have also set the reusable property when creating the socket.can some one tell what is the problem?

At last I could figure out the problem. But the problem was some where else. Above code does not have any arror. Initial Implementer of the code did not expose the real error. That’s why I could not figure out. Pardon me about the problem.
