Accepting connection from client

Question

Hello,
I want to create java server which accepts connection from client once and then continuously waits for request sent by client. Something same as select() call in C
Something of kind
Server.java:
Socket socket = server.accept();
while(true)
// listen for request ,
// if request received , create new thread for processing
// return response
I don't want to accept connection again and again

Thanks for the reply.
But even in this library, an new thread is created which keeps on doing accept() in while(true) and after accepting connection , another thread is created to do the processing.
But i want that once the connection is established between server and client i.e once accept() is done then just using that socket rest of processing i.e read()/write() is done , no need for accept() in while(true)
I have something like this
SenderReciever.java
public class SenderAndReciever
    private ServerSocket server;
    private int port = 6000;
    public SenderAndReciever()
        try
            server = new ServerSocket(port);
     catch (IOException e)
            e.printStackTrace();
    public void handleConnection()
        try
     Socket socket = server.accept();
         /* PROBLEM AREA */
         /* This while loop results in infinite loop .
          * if i move Socket socket = server.accept() inside while then it  accepts one connection
          * returns a response but then waits for another connection to be accepted
          * But i want connection once accepted , use the same socket for rest all communications
     while (true)
          new ConnectionHandler(socket);
     catch (IOException e)
          e.printStackTrace();
    public static void main(String[] args)
        SenderAndReciever senderAndReciever = new SenderAndReciever();
        senderAndReciever.handleConnection();
}ConnectionHandler.java:
class ConnectionHandler implements Runnable
      private Socket socket;
      public ConnectionHandler(Socket socket)
         this.socket = socket;
        Thread t = new Thread(this);
        t.start();
      public void run()
         try
            readData();
            processData();
            sendData();
         catch (Exception e)
            e.printStackTrace();
}
