how to clear the cache ?
Hello all,,,
In my project iam using eclipse for crystsal report for generating reports.
as youall are familar a .jsp page is required to load the crystal report..
My problem is this....
when i run the report first time i can see my .jsp page and user can submit the parameter and based on the users parameter the report is generated..
but when the user runs the report, its not clearing the old generated report,,i mean i cannot see my .jsp page for the user to submit the
parameter...
i tried using session.invalidate and session.removeAttribute and it was showing me the .jsp page for the user to feed the parameter...
but the problem is when the user clicks on the print icon on the report
its not printing its just showing the parameter or .jsp page...
how can i solve this problem?
thanks in advance
regards
jack
