Class AjaxServlet

java.lang.Object
  HttpServlet
      com.raritantechnologies.quickstart.taglibrary.ajax.AjaxServlet

public class AjaxServlet

extends HttpServlet

Handles state updates and monitoring of AJAX pages. Servlet is called by refresh code in pages with AJAX custom tags, for example as generated by the AjaxDisplayForm.

Depending on the current status of the background process, the AjaxServlet will either send a page with new data or a page that will call the AjaxServlet back after some delay time. For intermediate states, data will be sent back and requests will continue until some final state is reached. When the final page is sent, no further requests will be made to the AjaxServlet.
