The missing class appears top be part of the Sun portal implementation. It would appears that when you use Sun's Studio Creator2 tool that it builds Sun-portal specific portlets. I am not familiar with that tool so I do not know if there is a way to build standard portlets with it. You could try working your way through the JBoss Portal documentation, it has a pretty good getting started section for building your first portlet. And all it requires is a text editor.
