Your set-up must not be right. Perhaps you're missing the jface plug-in
somehow (it is included in RCP). You should follow-up on the platform
newsgroup if the problem persists.
BTW, once you get it working you might still not see the label, because it
might not get laid out. The layer to which it gets added might not have a
layout manager. Even if it does, you'd have to most likely provide a layout
constraint.
