Hi Experts,  

I have this code snippet file 1 and file 2 (see below) which start's and stop's jetty server. The code works fine when executed stand alone. I would want start and stop the jetty server from file 3 and remove the main functions from file1 and file 2. Please help

//File 1

package com.manu.example.test;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.ServerSocket;
import java.net.Socket;
import org.mortbay.jetty.Connector;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.bio.SocketConnector;
import org.mortbay.jetty.webapp.WebAppContext;

public class Start {

    private static Server server;

      public static void main(String[] args) throws Exception {
            
            server = new Server();
            SocketConnector connector = new SocketConnector();
            connector.setPort(8080);
            server.setConnectors(new Connector[] { connector });
            WebAppContext context = new WebAppContext();
            context.setServer(server);
            context.setContextPath("/");
            context.setWar("src/main/java/com/manu/test/example/web");
            server.addHandler(context);
        Thread monitor = new MonitorThread();
        monitor.start();
        server.start();
        server.join();
       
      }

    private static class MonitorThread extends Thread {

        private ServerSocket socket;

        public MonitorThread() {
            setDaemon(true);
            setName("StopMonitor");
            try {
                socket = new ServerSocket(8079, 1, InetAddress.getByName("127.0.0.1"));
            } catch(Exception e) {
                throw new RuntimeException(e);
            }
        }

        @Override
        public void run() {
            System.out.println("*** running jetty 'stop' thread");
            Socket accept;
            try {
                accept = socket.accept();
                BufferedReader reader = new BufferedReader(new InputStreamReader(accept.getInputStream()));
                reader.readLine();
                System.out.println("*** stopping jetty embedded server");
                server.stop();
                accept.close();
                socket.close();
            } catch(Exception e) {
                throw new RuntimeException(e);
            }
        }
    }

}

package com.manu.example.test;

public class Stop {

          Socket s = new Socket(InetAddress.getByName("127.0.0.1"), 8079);
        OutputStream out = s.getOutputStream();
        System.out.println("*** sending jetty stop request");
        out.write(("\r\n").getBytes());
        out.flush();
        s.close();

If your soecond file does not contain anynthing else then it should wioerk this way:


Add contents of main method in file 2 to the main method
in file 1 and when starting on command line

add argument like that:

java Start start  - it sghould start

java Start stop - it should stop


  public static void main(String[] args) throws Exception {

   if(args[0].equals("start")){
            
            server = new Server();
            SocketConnector connector = new SocketConnector();
            connector.setPort(8080);
            server.setConnectors(new Connector[] { connector });
            WebAppContext context = new WebAppContext();
            context.setServer(server);
            context.setContextPath("/");
            context.setWar("src/main/java/com/manu/test/example/web");
            server.addHandler(context);
        Thread monitor = new MonitorThread();
        monitor.start();
        server.start();
        server.join();
    }
  else 
 {

   Socket s = new Socket(InetAddress.getByName("127.0.0.1"), 8079);
        OutputStream out = s.getOutputStream();
        System.out.println("*** sending jetty stop request");
        out.write(("\r\n").getBytes());
        out.flush();
        s.close();
      }     


        
      }

Move the code from the main methods to proper non static methods as part of the classes.
Create objects of classes in file1 and file2 and invoke those methods.
