WriterAppender problem

[Matthew . Taylor]

Can anyone find the problem here?


I have a writer appender that writes to a bytearrayoutputstream.
I have a bytearrayinputstream wrapped in a bufferedreader that reads the
logged message from the stream once it has been logged.
However, my stream is empty, or at least the string conversion returns
null.

My code is :

BufferedWriter outputStream = setup.getOutStream();

cat = (AuditCategory) AuditCategory.getInstance(classFQN);

PatternLayout logLayout = new PatternLayout();

ConsoleAppender consoleApp = new ConsoleAppender(logLayout);
WriterAppender writerApp = new WriterAppender(logLayout, outputStream);

consoleApp.setThreshold(AuditLogPriority.DEBUG)
writerApp.setThreshold(AuditLogPriority.AUDIT);

cat.addAppender(consoleApp);
cat.addAppender(writerApp);

To setup the category with the correct appenders.

Then:

public void audit(java.lang.Object message) {
    System.out.println("message in audit method = " + message.toString());
    cat.audit(message);
    sendJmsMessage();
  }

  private void sendJmsMessage() {


    ByteArrayInputStream byteIn = setup.getInStream();

    BufferedReader myInput = new BufferedReader ( new InputStreamReader(byteIn) );

    try {System.out.println(myInput.readLine());}  // !!!!!!!!This returns null 
here!!!!!!!!!
    catch (Exception e){}

    String message = new String();

    try {
      // read the now characters and convert to string
      message = myInput.readLine();
    }
    catch (IOException e) {
      System.out.println ("Exception: " + e);
    }
    System.out.println (":::::::::::::::message == " + message);

    JMSProducer sendJms = new JMSProducer(message);
  }

With the arrayoutputstream stuff being done in  aseperate class:

public ByteStreamSetup() {

    // initialise the output stream
    byteOut = new ByteArrayOutputStream();
    // wrap the OP stream in the writer
    myOutput = new BufferedWriter( new OutputStreamWriter(byteOut) );

    // get the buffer contents and read it into our stream reader, wrapped in a
    // buffered reader which converts a stream of bytes to charatcers in one.
    byteIn = new ByteArrayInputStream(byteOut.toByteArray());

    //myInput = new BufferedReader ( new InputStreamReader(byteIn) );
  }

  public BufferedWriter getOutStream() {
    return myOutput;
  }

  public ByteArrayInputStream getInStream() {
    //return myInput;
    return byteIn;
  }

Is this a WriterAppender problem???
I can't work out where my message is getting lost??

Any ideas??

cheers
