I currently use the Job API to perform long-running task. But a task can also throw some kind Exception. What is the best way to display the error to the user(in the progressDialog i presume, but how?)

this is an example of what i currently do. but this does not display the error...

final Job job = new Job("Export Program") {
@Override
protected IStatus run(final IProgressMonitor monitor) {
monitor.beginTask("Some nice progress message here ...", 100);
try {
//Do long running task
}
catch (final Exception e) {
monitor.subTask("error");
monitor.done();
return Status.CANCEL_STATUS;
}
monitor.done();
return Status.OK_STATUS;
}
}

If its an error, then create an error status with necessary details and
return it.
