Hi, Rakesh.
The easiest way to do this is by using javascipt, because it seems to be
harder to pass these values between jsp files after the submission and you
need more bandiwdth. So i recommend you to do something like this:
<form id="foo" action="bla" onSubmit="return foobar()">
<input type=text name=txt1>
<input type=text name=txt2>
<input type=text name=txt3>
</form>
<script language="JavaScript">
function foobar() {
if ( (foo.txt1.value.value.length == 0) ||
(foo.txt2.value.value.length == 0) ||
(foo.txt3.value.value.length == 0) ) {
alert("please fill all of them");
return false;
}
foo.submit();
}
</script>
