You could use JGoodies Binding to bind the progress bar to your model. But your (view-)model must fire property change events for this to work. http://www.jgoodies.com/downloads/libraries.html I can post an example code on monday.

Example:

In your ViewModel:

private final PropertyChangeSupport changeSupport = new PropertyChangeSupport(this);

private int progress;

public void addPropertyChangeListener(PropertyChangeListener listener)
{
    changeSupport.addPropertyChangeListener(listener);
}

public void removePropertyChangeListener(PropertyChangeListener listener)
{
    changeSupport.removePropertyChangeListener(listener);
}

public int getProgress()
{
    return progress;
}

public static final String PROPERTY_PROGRESS = "progress";

public void setProgress(int progress)
{
    int old = this.progress;
    this.progress = progress;
    changeSupport.firePropertyChange(PROPERTY_PROGRESS, old, progress);
}

In your View:

BeanAdapter<ViewModel> beanAdapter = new BeanAdapter<ViewModel>(viewModel, true);
Bindings.bind(progressBar, "value", beanAdapter.getValueModel(ViewModel.PROPERTY_PROGRESS));
