Ajaxian: AjaxAnywhere: Ajaxian JSP Components

AjaxAnywhere is designed to turn any set of existing JSP components into AJAX-aware components without complex JavaScript coding. In contrast to other solutions, AjaxAnywhere is not component-oriented. You will not find here yet another AutoComplete component. Simply separate your web page into multiple zones, and use AjaxAnywhere to refresh only those zones that needs to be updated.

Mark 'reload-capable' zones of a web page with AjaxAnywhere custom tags.
Instead of submitting a form in traditional way, do it by AjaxAnywhere javascript API.
During request processing on the server-side, determine the zones to refresh. (You can implement this logic either on the client-side via JavaScript or on the server-side, via AjaxAnywhere API.)
On the server-side AjaxAnywhere will generate an XML containing only the 'updated' HTML.
On the client-side AjaxAnywhere javascript will receive the XML, parse it and update the selected zones. "
