The only (normal) reason a title bar will not appear is if you are using a Window or JWindow as the top level component, or if you call setUndecorated( true ) on your Frame or JFrame. Either of these circumstances should be easy to fix. If neither of these are the case, then maybe you have a bad install or a bug. Try uninstanlling and reinstalling the JDK, and if that doesn't work try posting it on Sun's Bug Database.
