To pass a parameter to an other JSP file, you can use the queryString (as long it doesn`t exceed 255 caracters, URL included, then use a POST maybe with input type=hidden to store the info but again, only text in both ways) or stock it in the server side (session, DB,ServletContext) and get it back in you other file. In this case, maybe use a value as a key to fetch a collection of information, it depends.
Can you give more detail on what you want to do ? There`s a lot of possibilities...
