How to stop a thread within a thread.

Question

I have two threads. A progress Bar thread and it starts yet another thread.
In the exception handler of the second thread how do I stop both the threads. thread.interrupt() seems to have to effect.
Thanks,
Veena

jdevel doesn't let me debug;
public class ProgressBarModel extends BoundedRangeModel {
BooleanValueWrapper stopFlag = new BooleanValueWrapper(false);
BooleanValueWrapper stopFlag2 = new BooleanValueWrapper(false);
IntValueWrapper value = new IntValueWrapper(0);
Thread newProgress = null;
Thread newProcessFile = null;
public void start(ActionEvent e) {
value.setValue(0);
stopFlag.setValue(false);
ProgressSimulator progressSimulator = new ProgressSimulator();
newProgress = new Thread(progressSumulator);
newProgress.start();
ProcessFileThreadMe processFileThreadMe = new ProcessFileThreadMe();
newProcessFile = new Thread(processFileThreadMe);
newProcessFile.start();
class ProgressUpdater implements Runnable
public void run(){
try
System.out.println(" ProgressUpdater is running");
//stop fag is true if it is set to true or if value is equals or greater
//than maximum
try { 
stopFlag.setValue(stopFlag.getValue() == true? true : (value.getValue() < maximum? false:true));
//run in loop until stop condition is met. Make sure system doesn't
//fail if values are initially set to the same value
while (!stopFlag.getValue() && value.getValue() != maximum) {
newProgress.interrupt();
newProgress = null;
} catch(Exception e) {
stopFlag.setValue(true);
stopFlag2.setValue(true);
class ProcessFileThreadMe implements Runnable
public void run(){
System.out.println(" ProcessFileThreadMe is running");
try
if(stopFlag2.getValue() == true) {
// interrupt this thread
// set it to null
return;
bean.persisit(value, stopFlag);
newProcessFile.interrupt();
newProcessFile = null;
catch (Exception exc)
stopFlag.setValue(true);
stopFlag2.setValue(true);
exc.printStackTrace();
In the bean the v alue is incremented
