I think at least part of your problem is no layout manager.
Try to get it to work with a layout manager, vs. no layout manager.
The rotation stuff looks okay, but I might call setBounds() vs.
super.setBounds(). Actually, if you were to use a layout manager.... you
wouldn't call those directly, but would setPreferredSize...
Also, you only need to override paintComponent(), not paint(). That way,
you can still have a border around the text field. This would only work if
you size the component properly (vs. calling setBounds() directly).
The JBuilder compiler is less strict than the javac one. For instance, last
time I checked you can have multiple public classes in a .java file if you
want.
