Would be nearly impossible to depict all interactions from
jsp to backend. Based on postings on this forum, I noticed that most people did shortcuts especially on the client/presetation tier side, ranging from representing the whole web GUI as a "subsistem". Others didn't detail the jsp-s, etc. Bottom line is that you want to represent what is esential for understanding your system and explain the rest. If you are like me, you will go through several iterations until you settle with a clean, simplified version.
