Hi, although it's not related to JSP :-) this is how I would do it:
* either have two frames , one very thin (hidden).
The frameset (top) will act as container.
1. add onSubmit() event handler to the form.
When the user submits, set a flag in the top frame (which
will persist after page change)
return false from it to abort submission
0. :-) on page load, generate dinamically the submit button
i.e.
<script>
if (top.flag == false) {
document.writeln ("<input type='submit' value='Upload'>")
}
</script>
So the user will see no submit button (although the submit
still works ).
* set a cookie with your state, take actions according to it
But, all this are in vain if s/he has disabled JS.
