jLabel.setText doesn't?

  To: comp.lang.java.gui
Hello everyone,
I have a Swing program that functions as a wrapper around a command
line program.
As the command line program runs it outputs various status messages.
I'ld like to pump these messages into the GUI specifically a jLabel but
theres a problem.
Try as I might I can't seem to get jLabel.setText(line); to output the
messages even though there is a call to System.out.println(line) that
IS working.

Here is my function, it's a little mangled due to me trying lots of
things to get this to work. But I think it makes it's point clear
enough...

    private int execMe(String[] args){
             try
            {
                Runtime rt = Runtime.getRuntime();
                Process proc = rt.exec(args);
                InputStream is = proc.getInputStream();
                try{
                        InputStreamReader isr = new
InputStreamReader(is);
                        BufferedReader br = new BufferedReader(isr);
                        String line=null;
                        while ( (line = br.readLine()) != null){
                            System.out.println(line);
                            jLabel3.setText(line);
                            int val = jProgressBar1.getValue();
                            if(val < 100){
                                jProgressBar1.setValue(val++);
                            }else{
                                jProgressBar1.setValue(0);
                            }
                            repaint();
                        }
                        jProgressBar1.setValue(100);
                    }catch (IOException ioe){
                        ioe.printStackTrace();
                    }
                // any error???
                //int exitVal = proc.waitFor();
                int exitVal = 0;
                System.out.println("ExitValue: " + exitVal);
                return(exitVal);
            }catch (Throwable t){
                t.printStackTrace();
            }
            return(1);
    }

Please note the jProgressBar is not working either :(

Any ideas on what else I can do?
Thanx in advance!

p.s. I've crossposted this to comp.lang.java.help as well since this
group only showed up AFTER I made that post :(
