Well, I know way that will almost certainly work and a way that might work. Focus management has been buggy in Java from the start. You would think this wouldn't be that hard to get right.
First the easy way that I think works. When a window opens, the system is trying to set the focus on the first focusable component you have added to the window. So make sure you add the Cancel button first thing. The reason this might not work is that the other rule it might be using is the focusing on the top-left focusable component. For the life of me I can't remember which rule Java uses. Now for the slightly harder one. You need to delay your requestFocus() until the system has already tried to focus on what it thinks should be focused. What I generally do is implement a WindowListener and in the windowActivated (or windowOpened), do the requestFocus(). But wait! That still doesn't work. You need to delay it even further. In the windowActivated method you need to create a Runnable class that does the requestFocus in the run() method. Then (again in the windowActivated) you do a SwingUtilities.performLater(myRunnable). This always delays the call enough so no one else overrules you. Good luck.
