An alternative is to use client-side javascript to set the form's action
property (URL) when the button is clicked and then submit the form. The
O'Reilly DHTML book says the action property is read-write in IE4+ and NN2+.
Instead of type=submit for the button, use type=button and the onclick
handler. Here is an example:
<html>
<head>
<script>
function mySubmit(myForm, submitURL) {
myForm.action = submitURL;
myForm.submit();
}
</script>
</head>
</body>
<form action="default.jsp">
<input type="button" value="one" onclick="mySubmit(this.form, 'one.jsp')" />
<input type="button" value="two" onclick="mySubmit(this.form, 'two.jsp')" />
</form>
</body>
</html>
