Hi Shashwati!
Off late, i came accross the same situation, and give tell u how did i
solve this..
When u come to the page page which adds a record to the table, come with a
parameter from previous page, let's say parameter 'addToken=yes' and add
record only if request.getParameter(("addToken").equals("yes")) and after
successful addition set addToken=no
This prevents addition of duplicate records with key hit F5
Hope this helps u
regards
venkat

Subject: Re-execution of servlet
