Sequence Diagram (UML)

Here are the first four sequence diagrams of my project. I had difficulty getting the first three done. This was because I was not sure of how to implement my system. I did some research online and decided to go with a Model View Controller (MVC) approach to the architecture (Sometimes called a model 2 approach).

In the diagrams I use one the second lifeline represents the GUI. This is made up of many different JSP pages though. So to simplify it I just represent it as one lifeline.
