I'm not sure what you mean by "clear the request object" but I assume that you are talking about the problem where an action will occur again if refresh is clicked.

Please read through this article paying special attention to the P-R-G (Post-Redirect-Get) pattern.

In my jsp i am having textbox and button, when i entered values in the textbox and click the button it goes to struts action class and
check for the validation for the textbox values, after that the status is set in request attribute and alert message is poulated in jsp.
This process is working fine but if i click the refresh button after completion of the process again the alert message is coming.
