Long running process, show progress in UI

I want to trigger a long running background process (coded as a service) from the ui. But I also want to show some progress of that task to the user.

How can I achieve this? (I want to not infringe on decoupling). Is there a best practice to solve it (combining design-patterns, eg. observer and command)?

Here is another example of a SwingWorker to do the heavy work, and to update a JProgressBar which is contained in the UI to show the progress to the user

Here is an example on how to use just the observer pattern to show progress in the UI. With JAVA sample code provided:

Have look a JProgressBar and changes for progress could be invoked from Runnable#Thread or SwingWorker
