Problem writting a Label

Question

I have the next problem. I throw a Thread that execs a command at runtime and I wanna writting a label to noting the user that the application is doing something.
Something like this:
    jLTextoInfo.setText("SAVING, WAIT PLEASE..........");       
    //I convert the wav file into an mp3 file
    ConversorWAV converWAV = new ConversorWAV(Configuracion.path+Configuracion.pathWav+Configuracion.archivoWAVtemporal, Configuracion.path+Configuracion.pathMp3+NOMPRACTICA+".mp3");
    converWAV.start();where the class ConversorWAV is something like this:
public class ConversorWAV extends Thread {
    try {
      // Se ejecuta una aplicaci�n que permite la conversi�n de un archivo wav a mp3
      // Mirar los par�metros introducidos en el ejecutable lame
      Process p = Runtime.getRuntime().exec("lame.exe  -b 32 -f -m j file.wav file.mp3");
          p.getOutputStream().close();
          p.getInputStream().close();
          p.getErrorStream().close();
          p.waitFor();
    }catch(Exception ex){
       MostrarError("ERROR al convertir el archivo de audio");}
}But the applet shows never the message with the text SAVING, WAITING PLEASE... I�m doing something wrong, but where? can anybody tell me something?
Thanks in advance!!

Answer 1

The problem is that I cannot print into the label. It doesn�t deppend if I print the label after or before I throw the runtime process.
I have the same result if i make:
jLTextoInfo.setText("SAVING WAIT PLEASE..........");
throw the runtime processor
throw the runtime process
jLTextoInfo.setText("SAVING WAIT PLEASE..........");I haven�t any problem with the runtime process. The only problem is when i wanna write the label. It makes nothing!!
Thanks in advance!
