So, line number 1 populates the category object.
In line number 2 categoryId(say categoryId of 'Networking') will determine which books (i.e 1) Network Fundamentals 2) Networking Concepts 3) Network Guide) to fetch from the database and populate the books object.

categoryNo is not the hyperlink.

still not able to figure out your problem... what are you displaying on this jsp is list of categories or directly list of books ? abd if books then of which category? and if category then why do you need to fire action class at line 2? you can give a submit button and then trigger action.
