I hava a class where the printout is in dos.....

Question

I hava a class where the printout is in dos now I want it to print out itin a Gui application or applet instead how do I do.
Here is the class file:
import filenet.vw.api.*;
public class QueueSample extends Object
public QueueSample(VWSession vwSession, Logger logger, String queueName)
QueueHelper queueHelper = null;
VWQueue vwQueue = null;
try
logger.logAndDisplay("\n~ Starting QueueSample execution.");
queueHelper = new QueueHelper(vwSession, logger);
if (queueName != null)
vwQueue = vwSession.getQueue(queueName);
else
String[] queueNames = queueHelper.getQueueNames(false);
if (queueNames == null || queueNames.length == 0)
logger.log("No queues found.");
return;
else
// iteratively get queues until first one with available elements is found.
for (int i = 0; i < queueNames.length; i++)
vwQueue = vwSession.getQueue(queueNames);
if (vwQueue != null)
if (vwQueue.fetchCount() > 0)
break;
// clear our reference
vwQueue = null;
if (vwQueue == null)
logger.log("Unable to retrieve a queue!");
return;
else
// display the contents of the queue
queueHelper.displayQueueContents(vwQueue);
catch (Exception ex)
if (logger != null)
logger.log(ex);
else
ex.printStackTrace();
finally
if (logger != null)
logger.logAndDisplay("~ QueueSample execution complete.\n");
//{{INIT_CONTROLS
public static void main(String args[])
String queueName = null;
String fileName = null;
Logger logger = null;
SessionHelper sessionHelper = null;
VWSession vwSession = null;
QueueSample sampleClass = null;
try
// did the user supply enough arguments?
if (args.length < 3 || (args.length > 0 && args[0].compareTo("?") == 0))
System.out.println("Usage: QueueSample username password router_URL [queue_name] [output_file]");
System.exit(1);
// the queue name is optional
if (args.length > 3)
queueName = args[3];
// the file name (for output) is optional
if (args.length > 4)
fileName = args[4];
else
fileName = new String("QueueSample.out");
// create and initialize the logger
logger = new Logger(fileName);
// create the session and log in
sessionHelper = new SessionHelper(args[0], args[1], args[2], logger);
vwSession = sessionHelper.logon();
if (vwSession != null)
// create the sample class
sampleClass = new QueueSample(vwSession, logger, queueName);
catch (Exception ex)
if (logger != null)
logger.log(ex);
else
ex.printStackTrace();
finally
// logoff
if (sessionHelper != null)
sessionHelper.logoff();
}

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!");
