Hello!
Submit is a type of parameter and when you try to get it from request it
returns null;
try this
HTML:
<input type="Submit" name="action" value="OK" >
<input type="Submit" name="action" value="Cancel">
servlet:
String action = request.getParameter("action");
(In jdk >= 1.2.2 use request.getParameterValues("action")[0])
