What exactly is your doubt?
Probably you used a iterator (c:foreach maybe?) to build the table. You can use the same structure to put the hyperlink and call the
Servlet. Into that hyperlink, send a parameter (maybe an ID) to servlet distinguish which row the user has selected.
Try to post some code to people help you.
