Updation on checkboxes in JSP

[Manish Sahni]

hi,

i am making a module in a project which have various checkboxes , and an updation button.

While clicking on update button,the values are updated in my database , and the next time i visit the same module , the values previously checked remains checked.

Now when i uncheck some values and update then also the database is updated .
However while doing it thrice the database value stops updating and i see the previous (on second time visit) checked boxes checked.

Please tell me why the updation is not working on revisiting the page again?

Thanks in advance..

Is it possible to see at least the jsp code used for writing the checkboxes, the code written to check (uncheck) the checkboxes, the servlet code that gets the checkboxes from the request and the query used to perform the update operation?

Thank you
