[wxdqz]

Hi,I'm new to servlet programming. I need the syntax to invoke a servlet fromHTML or ASP page. I'm takingan input on the page like Name. And I want to pass this as a parameter tothe servlet and the servletverifies whether there was some name written or not. Accordingly it saysHello + user name or displays amessage "You did not enter anything"Thanks in advanceManika
