first. Sometimes, javascript will still submit the form even though you
return a false in the method. But, in your case, it is kind of strange... | m******t

So:
1. You don't need the onclick. Instead move checkForm() to
the form's onsubmit.
2. You don't need to call form.submit(). Instead either return
true or false depending on whether the input is valid.
Oh, and none of this stuff has anything to do with java, by
the way. 8-)

: I have javascript like:
: function checkForm(form, url) {
: ...
: if ( valid == 1 ) {
: form.action = url;
: form.submit();
: }else {
: alert( 'error message' );
: return;
: }
