<strong>AJAX</strong>

The Ajax technique accomplishes this by using the following technologies:

JavaScript that allows for interaction with the browser and responding to events
The DOM for accessing and manipulating the structure of the HTML of the page
XML, which represents the data passed between the server and client.
An XMLHttpRequest object for asynchronously exchanging the XML data between the client and the server.
The following graphic shows how these technologies work together to update a piece of a page with new data from the server.

Figure 1: General Sequence of Ajax Request

Figure 1 illustrates the following steps in a generalized Ajax request:

The user generates an event, such as by clicking a button. This results in a JavaScript call.
An XMLHttpRequest object is created and configured with a request parameter that includes the ID of the component that generated the event and any value that the user might have entered.
The XMLHttpRequest object makes an asynchronous request to the web server. An object (such as a servlet or listener) receives the request, processes it, and stores any data in the request to the data store. In the case of Ajax-aware JavaServer Faces components, the object that processes the request is a PhaseListener object. We'll cover that more later in the document.
The object that processed the request returns an XML document containing any updates that need to go to the client.
The XMLHttpRequest object receives the XML data, processes it, and updates the HTML DOM representing the page with the new data.

In the below Example

Run ->Call.jsp it invokes db.jsp through Ajax
