Description of workflow required on existing Java application

I have a running Java management application complete with a HSQL database and source files. I require a description of about 8 pages of how the application works, workflow, what classes does it use, the relation with the database, etc. The project is here [login to view URL] so you can take a look at it. After you have provided me this there will be a separate job if you want of disabling a few menus. Rather simple I think after you have understood how the app works.
