This Java ME tip explains use of handset (Mobile) as network Server. This tip may be helpful for game developers who are coming up with applications which work on more than one mobile device. This may help them to make one handset controlling the activities of the other.

 String getResponse(String request) {
    String response="";
    
    try{
        // Open a socket connection
        //It is trying to connect to a server at port no 8080
        SocketConnection soc=Connector.open("socket://my.com:8080");
        
        //Open input and output streams
        InputStream is  = soc.openInputStream();
        OutputStream os = soc.openOutputStream();
        
        //Sending request to server
        os.write(request.getBytes());
        
        //Now read response from server one byte at a time
        int ch = 0;
        while(ch != -1) {
            ch = is.read();
            response+=(char)ch;

    }catch(Exception e){}
    
    return response;
