We use:
1) Struts token to prevent reload (F5) problems,
2) page redirection in a "in process page" for long transactions
(usually with JMS)
3) javascript to prevent user doubleclicking buttons.
We use Xkins and our buttons are images generated by xkins, and have
taglibs to generate this buttons and all is done by these taglibs, but
the javascript concept is as follows:
<script>
var buttonsEnabled = true;
function disableButtons() { buttonsEnabled = false; }
function enableButtons() { buttonsEnabled = true; }
function checkButtonValid() {
if(buttonsEnabled) {disableButtons();return true;} else {return
false;}
}
</script>
<input type="submit" onclick="return checkButtonValid()"/>
Cheers.
Guillermo

EnterInfoAction
----------------------
saveToken(request);
enterInfo.jsp
---------------------
nothing required - the <html:form tag places an <input type="hidden" tag
for
you
ProcessInfoAction
-------------------------
if ( !isTokenValid(request, true) ) {
//incorrect token
}
I'm pretty sure this is how it works, but it's been a while, so I may
have
something mixed up.
