Prob while refresh the page in weblogic8.1 workshop

[Bikash Paul]

Hi guys!
How can i do in jsp(actually this is on html) to be submitted only when i click the submit button?Right now, i already submitted the form and then press the refresh button of the browser it is submitted again.i can i prevent this one? I am using weblogic8.1 workshop, Struts Framework .
I have tried with below code in .jpf file

//Method declaration starts
{
saveToken(getRequest()); 
 if (isTokenValid(getRequest())) {
      //doing some operations
      resetToken(getRequest());
    }
 }//Method ends

Always isTokenValid(getRequest()) method is returning false only.
Can anyone pls help me in this regard.
Thanks
Bikash
