Hi Sam the approach I'm taking is to completely leave out the details of the GUI implementation. I only indicate a GUI component in the Component Diagram. I believe this is enough as the GUI implementation is beyond the scope of the assignment.
I would like to take the same approach for the Web front-end, therefore only indicate a generic JSP component (which would include all JSPs required as part of the view layer). Unfortunately looking at Cade and going through this forum it looks like it is quite important mentioning (in the Component Diagram) which JSPs are required and when.
