JSP normally uses HTTP or HTTPS at the application layer. UDP is a transport layer protocol, so I dont see how or why you could specify its use. What you are asking, is like asking how to use token-ring for jsp. JSP is a presentation technology, not a networking API. James
You could certainly have a helper class (possibly a JavaBean style) that did the UDP, but as James says, JSP is for presentation. People keep trying to cram all sorts of computation into their actual JSP page code - I just can't understand why they try it. Bill
