Redirecting System.out stream to a TextArea

I hope this isn't a stupid question--I'm blanking pretty hard.
I want to use System.setOut() to direct standard output to a TextArea within a Frame. Is there a way to setup a TextArea to receive text from an output stream, or is an intermediary of some sort necessary?
I feel like this is pretty easy, but I'm stumbling. That's what I get for doing J2EE for a year rather than GUI. :P
Any input is appreciated!

Here's the compiled and tested code...I learned some good stuff from this link as to why my simpler approach didn't work:
http://www.devx.com/upload/registered/features/javapro/1999/11nov99/tl1199/tl1199.asp
Here is my code:
  class OutRouter implements Runnable
    PipedInputStream pipeIn = null;
    JTextArea textArea = null;
    OutRouter( JTextArea ta, PipedOutputStream pos)
      try
        pipeIn = new PipedInputStream(pos);
      catch(IOException ioe)
        ioe.printStackTrace(System.err);
        System.exit(1);
      textArea = ta;
    public void run()
      String line = null;
      BufferedReader pipeReader = new BufferedReader(
        new InputStreamReader(pipeIn));
      try
        while(true)
          Thread.sleep(100);
          if(pipeIn.available() == 0)
            continue;
          line = pipeReader.readLine();
          if(line == null)
            continue;
          System.err.println("Line = " + line);
          final String fLine = line;
          SwingUtilities.invokeAndWait( new Runnable()
            {public void run()
              { textArea.append(fLine + "\n"); }
      catch(InvocationTargetException ite)
      { ite.printStackTrace(System.err); System.exit(1); }
      catch(InterruptedException ie)
      { ie.printStackTrace(System.err); System.exit(1); }
      catch(IOException ioe)
      { ioe.printStackTrace(System.err); System.exit(1); }
  }

  • Redirecting System.out to a JTextArea

    How can I redirect the System.out Stream into a JTextArea?
    I found the method System.setOut(PrintStream out) but I don't know

    I don't know if this is the most efficient way but it provides an example of using Pipes:

  • Redirect system.out.println() to a file

    hi all,
         how can i redirect all the console prints to a txt file in java application? i have used system.out oftenly in many class throught the
    application. is there any way to redirect all those console prints to a
    txt file by converting or assigning the System.out stream to a stream for filewriter or
    somthing like that, so that whenever system.out.println() is executed
    the content is written to a file insted of on the console.
    thanks in advance
    Sojan

    Actually,System.setOut(new PrintStream(new FileOutputStream("output.txt"), true));
    System.setErr(System.out);since setOut wants a PrintStream and not just some OuputStream...

  • Reading System out stream ?

    Hi,
    I don't know whether I am asking a stupid question or not . But my problem is that in my thousand lines of code i wrote number of System.out.println(".....") statements to describe various situations / state of program which write those strings of messages to standard output i.e console . Here at this point of situation I was wondering that is there a possible way that i could read System.out stream by concurrently running a thread who could look on this stream and could redirect it to a file where i want. By achieving this I don't need to go at every piece of code where i have written System.out.println(".....") and change it to get desired result.
    If it is possible , please let me know ?
    Thanks in advance,
    Hemant.

    A suggestion - next time, set up a boolean - call it maybe "debugFlag" and check it befor a system.out write. That way all that's needed is to reset the flag and recompile when it goes to "production".
    And then the other possibility is to use your editor and do some global change all in your code.

  • Redirecting System.out to a textfield

    I want the output created by System.out (especially error messages) redirected to a textfield in stead of the console. How can I do this?

    this is how I've done it. Just create a new instance of this class and pass in your TextArea. It redirects System.out and checks for messages on System.out every 5 seconds.

              throws Exception
              this.text = text;
              PipedOutputStream pout = new PipedOutputStream();
              System.setOut( new PrintStream( pout ) );
              in = new InputStreamReader( new PipedInputStream( pout ) );
              t = new Thread( this );
              t.start();
         public void run()
              while( true )
                   try
                        StringBuffer buffer = null;
                        while( in.ready() )
                             if ( buffer == null ) buffer = new StringBuffer();
                             buffer.append( (char)in.read() );
                        if ( buffer != null )
                             text.append( buffer.toString() );
                             java.awt.Rectangle r = new java.awt.Rectangle();
                             text.computeVisibleRect( r );
                             text.repaint( r );
                        t.sleep( 5000 );
                   } catch (IOException ioe) {

  • Redirect, System.out  ?

    Hi.
    I want to redirect System.out to a Swing Component like JTextArea, etc.
    try with printstream, Reader, etc. but i dont know how.!.
    I want to see, messages (The standard out) in a Swing Component.
    plis some help..
    tnks.

    I was using the Redirect method you made edna for my software and it works wonderfully when using strings, unfortunately I ran in to a strange problem which is fitting since my current objective is very strange.
    I am writing a piece of software that has an embedded jython interpreter in it. When I execute my jython scripts all the output went to the console and I had no direct way of saying append to this particular text area since I wasn't able to pass my Java GUI class in to the script.
    Thus redirecting my output with your method came in quite handy. This is where the problem comes in. I tried the println function in my regular java classes and all the primitive types worked fine, but within in the script only String worked. Here is the code for the println function
    PrintStream stdout = new PrintStream(System.out) {
       public void println(String x) {
          outputTextArea.append(x + "\n");
       public void println(int x) {
          outputTextArea.append(x + "\n");
       public void println(boolean x) {
          outputTextArea.append(x + "\n");
       public void println(Object x) {
          outputTextArea.append(x.toString() + '\n');
    };Here is the sample Jython code:
    import JythonScripter
    System.out.println(4) #fails to print correctly
    System.out.println("HelloWorld") #works
    System.out.println(10) #fails
    System.out.println("Goodbye Cruel World") #works
    If you have any advice on why strings would work but not other types I would greatly appreciate it.

  • Redirecting System.out() output to a JTextArea control

    I want to be able to redirect System.out() and System.err() messages to a JTextArea control:
    I know how to redirect output to a file as follows:
    FileOutputStream fos =
    new FileOutputStream(filename, true);
    PrintStream ps = new PrintStream(fos, true);
    System.setOut(ps);
    System.setErr(ps);
    How can I set it up so that I can recognise when messages have been to System.out() with a view to displaying the message within the JTextArea?
    I guess I need to set it up so that the JTextArea control acts as an Observer. The bit I'm having difficulty with is figuring out how I can automatically determine when information has been written to System.out()?
    Hopefully I'm explaining my issue in enough detail and clarity.
    thanks
    - Garry

    I would suggest you set up a separate thread to monitor System.out. Use a PipedOutputStream and redirect System.out to that, then connect that to a PipedInputStream that your other thread is continually waiting to read. Each time that thread reads a line, it should append the line to the JTextArea, using SwingUtilities.invokeLater.
    This is just a rough outline of something that might work. Hope it helps.

  • Is System.out stream synchronized?

    Hi,
    I am using the System.out stream to print various logging messages
    by different threads.
    I am using System.out.println
    Is this thread-safe?
    The messages themselves are only for development, they are not essential,
    that's why I haven't bothered to set up any synchronization mechanism...

    Hi,
    are you sure?
    On what grounds do you claim this?
    The Javadocs do not specify it.
    Thanks.If you question the correctness, it's time for you to do your own research.

  • Redirecting System.out?

    I am working with a team, and I am testing a standalone Java application using separate unit tests. The program takes text input and outputs some text results, but the way it is set up, it will output directly to System.out as soon as it needs it. I am not in control of the way it outputs the results.
    I need to capture all of the results from System.out, and compare them to what I know should be printed out. How do I do this without touching the original source files? Is there a way to do it purely in Java (my backup is to use shell scripts, but I really don't want to)?

    Well, you don't need to change all the source files, but you will need to
    change the source file with your main method.You don't even have to do that: build a Wrapper class with its own main
    that redirects System.out to a file and calls the Application.main afterwards.
    Instead of starting the Application, start the Wrapper.
    kind regards,
    Jos

  • Is it possible to redirect System.out and System.in for a thread

    I would like to run two threads. One should keep writing to System.out and System.in. The other thread output written to System.out and System.in shoudl be captured and written to a file. Is this possible? I don't think so, but perhaps someone know some workaround.
    rasped

    hmmm sure it's possible. You can write an outputstream that does different things depending on which thread is running, and then set system.out to a printstream that writes to that outputstream.
