Demo 3: Build and create a Window NT Service

Function: Convert JAR archive into Executive.

Part 1: Build a java program and create a jar charchive

1. Compose a java program D:\test\HelloService.java：

    The function of the demo service: Listen on a port (for example 1234). Create a new thread when a client connects. Then, the service thread will echo back whatever the client send, until 'q' to to stop serve:

package test;

import java.io.*;
import java.net.*;

public class HelloService implements Runnable
{
    // socket
    private Socket m_sock;

    // Constructor
    public HelloService(Socket sock)
    {
        m_sock = sock;
    }

    // Runnable method
    public void run()
    {
        try
        {
           BufferedReader in = new BufferedReader(
                new InputStreamReader(m_sock.getInputStream())
            );

           PrintWriter    out = new PrintWriter(
                m_sock.getOutputStream()
            );

           // welcome
           out.println("---- Welcome! Type 'q' to EXIT: ----");
           out.flush();

           // echo back until 'q'
           String line;
           while( (line = in.readLine()) != null )
           {
               if( line.equalsIgnoreCase("q") )
                   break;

               out.println(line);
               out.println();
               out.flush();
           }

           // close socket and exit this thread
           m_sock.close();
        }
        catch(Exception e)
        {
            e.printStackTrace(System.err);
        }
    }

    public static void main(String[] args) throws Exception
    {
        // listen: 1234
        ServerSocket listen = new ServerSocket(1234);

        while(true)
        {
            // accept
            Socket socket = listen.accept();

            // open thread to serve
            Thread thread = new Thread(new HelloService(socket));
            thread.start();
        }
    }
}

2. Compile, we get HelloService.class:

D:\>javac -target 1.2 test/HelloService.java

3. Use jar.exe to create service.jar:

D:\>jar cvf service.jar test/HelloService.class

Part 2: Use tool to create .exe file

1. Download and install this free tool:

[Free Edition Download]

2. Select the jar file, then press next to continue:

3. Select the application type. Here "Windows NT Service":

4. Input the main class to start and the service name:

5. Type in the exe filename you want to get:

6. Press next, the exe file is generated.

Part 3: Run the Exe file

1. Windows NT Service installation and startup:

2. Use the service. Let's us telnet:

D:\>telnet localhost 1234

3. Service stop and uninstallation:

4. Test the service program on console:

The service is running, and can be tested by telnet equally.

5. Download the program and result exe in this demo:

[service.zip] - 15kb
