you need to change your architecture a bit to use AJAX.
you will have 2 jsp programs:
1. resultset.jsp that does the database access, and outputs the result set either as a formatted table of results, XML, or JSON.
2. main.jsp that is used to send javascript to the client. The javascript then initiates an AJAX call to resultset.jsp, in a loop, so the data is refreshed.
