AJAX in 50 simple lines: Requesting HTML and Producing JSP
First we need a simple JSP as a service. http://localhost:8080/jsp/request.jsp?name=Chris
The JSP simply returns the length of the string. The format is simple text, no XML.
Then we need a HTML page. It shows two text fields. One with an attached onkeyup() listener and one which displays the result, the length of the string in the first text field. The AJAX-request is inside a function called call() by the listener.
