modify java programs

We need a good Java programmer to make some changes on our jsp files and maybe java program files. A new button will need to be added in asp page and link to jsp page every time it is clicked. Cause number & document type from asp page will fill in to jsp page automatically and jsp programs use these values to search and display list of [login to view URL] now, asp pages and jsp programs are working fine but they work separately way. User needs to manually choose type, categories and type cause number in the field for jsp programs to display documents. We want it to be automatically. We want it automatically receive values from asp page when the button is clicked and display the documents without need users to login or manually select or key in the [login to view URL] is simple project (only 5 jsp files ) with a small budget. I need it to be done in 3 days.
