If you are developing Ajax-enabled applications, you also have the
benefit of using the same scripting language on the client and the
server if you use JavaScript technology on the server side.

He has written extensively about relational database technology,

Pros Page authors do not need to know JavaScript technology, CSS, and
DOM.

Once you learn to master one of these frameworks, you'll find it helps a
lot with developing Ajax-aware applications and resolving
incompatibility issues and the other common Ajax pitfalls.

What's more is that the modularity of the components makes them more
toolable. In addition, you have server-related choices regarding Ajax.

the do-it-yourself approach when you need fine-grained control your web

technology that is key to Ajax is XMLHttpRequest, an object that is used
to exchange data between the web client and web server.
You'll notice that a major part of that code is client-side JavaScript
technology code. The first part of that URL, faces, is mapped to a
FacesServlet servlet.
You can see that by examining any of the Ajax-enabled JavaServer Faces
components in the Blueprints Catalog. Using a phase listener is only one
of several ways to handle JavaServer Faces technology requests.

This requires the server to do a full refresh of the page. Creating and

Pros Hides low-level Ajax "plumbing". In this way, page authors can make
use of all of the Ajax capabilities, while at the same time the
complexity of the components' JavaScript is hidden from them.
