To get a task to run with the TaskMonitor provided with the netbeans application template, you must create the task by extending org.jdesktop.application. An example task is shown below which just generates random numbers to increment the status bar.

public class OpenTask extends org.jdesktop.application.Task {

OpenTask(org.jdesktop.application.Application app) {
super(app);
}
@Override
public Void doInBackground() {
Random random = new Random();
int progress = 0;
//Initialize progress property.
setMessage(“Opening the file”);
setProgress(0);
while (progress < 100) {

//Sleep for up to one second.
try {
Thread.sleep(random.nextInt(1000));
} catch (InterruptedException ignore) {
}
//Make random progress.
progress += random.nextInt(10);
setProgress(Math.min(progress, 100));

}
return null;
}

The second thing that you need to do is create an action in the appnameView.java file to start the task. The trick to getting the task monitor to work is to start the task through the TaskService as shown below. Using the execute method on the task itself does not register it with the taskmonitor created by netbeans. The fourth line below was my breakthough.

@Action
public void OpenFile() {
OpenTask foo= new OpenTask(MyApp.getApplication());
getApplication().getContext().getTaskService().execute(foo);
}
