Hi every one,

Iam using struts in my application,
whenever I clicked on the refresh button of the browser the form is getting submitted twice.
I tried to use saveToken() and isTokenVaild() methods but still, the form is getting submitted when I click on the Refresh button.
please see my code below.

please let me know what is wrong with my code.

Thanks,
Madhu.

public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {

String forward = Constants.FWD_SUCCESS;
String action = mapping.getPath();

HttpSession session = request.getSession();

if(action.equals("/EdisTrees")){


EdisTreesHelper treeHelper = new EdisTreesHelper();

if(!isTokenValid(request)){
treeHelper.processTreesDeatils(mapping, form, request, response);
resetToken(request);
}else{
//do nothing;
}
}
saveToken(request);
return mapping.findForward(forward);

}

Are you calling saveToken in the action that initially displays the page? Does your page have an html:form tag? If you look at the generated html source (view source) you should see a hidden field that contains the token id.
