*** FREE REMOTE DEBUGGER UTILITY ***

Question

I just created this "remote debugger" last week because I wanted to get runtime output from my servlets without having to resort to finding the server logs...scanning them...etc. It can also be used to log info locally. Here is the code for the screen logger:
package com.mycode.remotedebugger.applet;import javax.swing.*;import java.awt.*;import java.awt.event.*;import java.net.*;import java.io.*;public class CRemoteDebugger extends JApplet implements Runnable{   boolean isStandalone         = false;   static ServerSocket m_socket = null;   JScrollPane jScrollPane1     = new JScrollPane();   static Thread runner         = null;   static Socket connection     = null;   BorderLayout borderLayout1   = new BorderLayout();   JTextArea jTextArea1         = new JTextArea();   /**    * Constructs a new instance.    */   /**    * getParameter    * @param key    * @param def    * @return java.lang.String    */   public String getParameter(String key, String def) {      if (isStandalone) {         return System.getProperty(key, def);      }      if (getParameter(key) != null) {         return getParameter(key);      }      return def;   }   public CRemoteDebugger() {   }   /**    * Initializes the state of this instance.    */   /**    * init    */   public void init() {      try  {         jbInit();      }      catch (Exception e) {         e.printStackTrace();      }   }   public boolean isConnected()   {      return m_socket != null;   }   private void jbInit() throws Exception   {      this.setSize(new Dimension(400, 400));      this.getContentPane().add(jScrollPane1, BorderLayout.CENTER);      jScrollPane1.getViewport().add(jTextArea1, null);      runner = new Thread(this);      runner.start();   }   public void run()   {      try {         m_socket = new ServerSocket(6666);         while(true)  {            InetAddress ia = InetAddress.getLocalHost();            connection = m_socket.accept();            InputStream is = connection.getInputStream();            BufferedReader br = new BufferedReader(new InputStreamReader(is));            String strLine = br.readLine();            while(strLine != null)  {               jTextArea1.append(strLine + "\n");               jTextArea1.setCaretPosition(jTextArea1.getDocument().getLength());               strLine = br.readLine();            }         }      } catch(Exception e)  {      }   }   /**    * start    */   public void start() {     setLookAndFeel();   }   /**    * stop    */   public void stop() {   }   /**    * destroy    */   public void destroy() {    if(m_socket != null)  {      try  {         m_socket.close();      } catch (IOException ioe)  {      }      m_socket = null;    }    if(runner != null)      runner = null;    if(connection != null)  {      try {         connection.close();      } catch(IOException ioe)  {      }         connection = null;    }   }   /**    * getAppletInfo    * @return java.lang.String    */   public String getAppletInfo() {      return "Applet Information";   }   /**    * getParameterInfo    * @return java.lang.String[][]    */   public String[][] getParameterInfo() {      return null;   }   /**    * main    * @param args    */   public static void main(String[] args) {      CRemoteDebugger applet = new CRemoteDebugger();      applet.isStandalone = true;      JFrame frame = new JFrame();      frame.setTitle("Remote Debugging");      frame.getContentPane().add(applet, BorderLayout.CENTER);      applet.init();      applet.start();      frame.setSize(400, 420);      Dimension d = Toolkit.getDefaultToolkit().getScreenSize();      frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);      frame.setVisible(true);      frame.addWindowListener(new WindowAdapter() {        public void windowClosing(WindowEvent e) {          if(m_socket != null)  {             try  {                m_socket.close();             } catch (IOException ioe)  {             }             m_socket = null;          }          if(runner != null)            runner = null;          if(connection != null)  {             try {               connection.close();          } catch(IOException ioe)  {          }          connection = null;        }           System.exit(0);        }      });   }   void setLookAndFeel(){      try {         UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());      }      catch(Exception e) {         e.printStackTrace();      }   }}
I compiled this and put it into a jar file for easy running via a shortcut on my desktop.
Here is the static function you would put either in your application/applet or perhaps in some utility class that you import:
package com.mycode.common.utilities;import java.awt.*;import java.awt.event.*;import java.net.*;import java.io.*;public class RemoteDebugMessage{   static Socket m_socket            = null;   static PrintWriter serverOutput   = null;   /**    * Constructor    */   public static void Print(String strClient, int nPort, String strMessage)   {      try {         m_socket = new Socket(strClient,nPort);         if(m_socket != null)  {            OutputStream os = m_socket.getOutputStream();            if(os != null)  {               serverOutput = new PrintWriter(new BufferedOutputStream(m_socket.getOutputStream()),true);               if(serverOutput != null)  {                  serverOutput.println(strMessage);               }            }         }      } catch(IOException ioe)  {      }      try {         m_socket.close();         m_socket = null;         serverOutput = null;      } catch(IOException ioe)  {      }   }}
The "server" side listens on port 6666 (you can always change to whatever port you like and recompile) Then, in your code where you wish to watch messages in realtime, you call the static function above:
RemoteDebugMessage.Print("MachineName",6666,"This is my message!");
Where "MachineName" is the name of your pc.

Thank god for the scrollbars. :)
Maybe you should repost and add proper newlines.
