Implement a Execution Log in Java

问题

Coming from a WPF world, I am having a hard time implementing some basic stuff in Java. I need to execute a *.JAR file from another java GUI application. This JAR file takes minutes to finish, and I want the GUI not to freeze.

So, my initial solution would be: create a SwingWorker class to call a command line in background.

My main concerns are:

1. I need to get the console output from the *.JAR file and show it in the GUI. Is it possible to update the GUI from a background thread?

2. Is it possible to cancel the thread from a user input?

3. How do I get notified that the thread is finished?

4. Is my solution a good one?
