Unlimited mouse moves/drags

There are lots of situations where you want to use the mouse for something other than controlling the cursor on the screen. For example, 3D object viewers often use the mouse to rotate your viewpoint, or a game might use the mouse to steer a spaceship.
I'm trying to figure out how to implement this in Java. To a first approximation, it's simple. Call Toolkit.createCustomCursor() to create an invisible cursor. Set that as the cursor on your window. Now just listen for mouse moves and drags, and respond to them appropriately.
The problem is that you're still really just moving a cursor on the screen. You stop getting mouse move events as soon as the mouse leaves the window. Mouse drag events keep coming, but the cursor is still limited to the screen dimensions. So you're flying your spaceship, and suddenly hit a wall! No, it isn't a force field in space. :) The cursor has just run into the edge of the screen.
Obviously native applications manage to find a way around this problem. Does anyone know a way to do it from Java?
