Currently, Web-based applications are being developed for almost every
industry, providing online services that people can access anytime and
anywhere. Such services range from online tutoring to virtual shopping,
helping people complete their tasks with comfort and ease. Web-based
systems are quite attractive because there are no platform constraints and
installation requirements. With the emergence of Web 2.0, there is a lot of
momentum to build intelligent Web applications that provide more intelligent
services. This article
describes an architecture for intelligent Web-based applications and discusses
each component in the application with implementation details.

Create optimized Dojo builds for your custom Dojo artifacts
Create a custom Dojo build for your custom widgets without
including any modules from the dojo/dojox/dijit packages into your build output.
Custom Dojo builds reduce the number of modules to be downloaded by combining all
the modules into a single file, thereby reducing the number of network calls
required for the individual module files. These techniques were developed with a
real-world project where compact packages were a requirement. This article helps you to create
optimized Dojo builds using the Dojo build tool.

High-performance Web development with Google Web Toolkit and Eclipse
Galileo
By now, you have probably heard of Google Web Toolkit (GWT). You know
that it lets you write your Web applications in the Java programming language that is compiled into
JavaScript to run in Web browsers. This lets you be more productive by taking
advantage of Java's static typing and great tools like Eclipse. You have may
seen some of the useful and stylish widgets built on top of GWT. What
you may not know is that GWT lets you create high-performance Web
applications. In this article, we look at how you can use the Google
Plug-in with Eclipse Galileo to tap into the performance features of GWT, such
as compiler optimizations, deferred binding, and Ajax optimizations. Developer
performance is still an important part of GWT, so along the way, we will also
show you how tweak the Google Plug-in for Eclipse to increase your
productivity.

Automatically update a Web page with dynamic elements
You may know how to hide and display optional JavaServer Faces (JSF)
components by using JavaScript and Cascading Style Sheets (CSS) in
standard JSF components. To do this, you would first need to identify all JSF
components and write them into JSF pages. But, that is impossible to do when you are
developing a Web page that contains dynamic elements that are unknown until
run time. With this article, learn how you can clear old UI components while
automatically updating the dynamic
elements of a Web page, as well as how to use Java
code to add new
elements and put them into their proper spot on a Web page. You'll also learn how to bind
different event handlers to different dynamic elements of a Web page, how to
register a listener listening to changes of server-side data to invoke a page
refresh, and how to use Asynchronous JavaScript and XML (Ajax) techniques to refresh only the dynamic parts of the Web page.

Build a RESTful Web service using Jersey and Apache Tomcat
Representational state transfer (REST) was introduced in early 2000 by Roy Fielding's doctoral dissertation.
However, in the Java community, it was not standardized until JSR 311(JAX-RS) was
finalized in 2008. The first release of its reference implementation is
even later. In this article, I introduce Jersey, which is the reference
implementation of JSR 311, by describing its essential APIs and annotations. I'll
also show you how you can smoothly transfer from servlet-style services to
RESTful services by integrating Jersey into Apache Tomcat.

Implement a real-time server push in Ajax applications using socket-based RIA
technologies
The new range of advanced user interface (UI) applications requires some
aspect of the "server-push" feature so clients can be notified immediately of
any server-side changes. Unfortunately, the HTTP spec does not address the issue of any
server-side initiated communication, so the server-push has traditionally been
implemented through client-side polling. This technique tends to generate a lot
of unnecessary traffic and non-optimized applications. Thankfully, certain Rich
Internet Application (RIA)
technologies do allow the opening of a dedicated socket channel, with the back-end server
providing an opportunity for Asynchronous JavaScript and XML (Ajax) applications to piggyback on their APIs and
implement a server push. This article explores this technique in a variety of
ways, and helps you understand it well enough to begin your own implementation.

ICEfaces and Google Translate
Globalization has had an enormous impact on our lives and cultures. As a
result, translation is becoming an increasingly important tool to enhance
understanding between cultures. Organizations try to use Web technologies with
different languages, scripts, and cultures, and developers search for new
technologies that will help them create efficient applications as quickly as
possible. Fortunately, JavaServer Faces (JSF) simplifies life for application developers, making it
possible for them to focus on the view without needing to know the underlying
markup or scripts. ICEfaces, an integrated Asynchronous JavaScript and XML (Ajax)
application framework, enables Java Platform, Enterprise Edition (Java EE) application developers to easily create and deploy thin-client,
rich Internet applications in pure Java code. This tutorial describes how to develop Web applications using
JSF with the translation option.

Accessibility in Web 2.0 technology
Accessibility has become a hot topic as increased awareness and growing
requirements demand that applications take into account the needs of all
potential users. Accessibility covers not only the Web application, but document,
desktop application and hardware, and so on. In the Web application domain,
making static Web pages accessible is relatively easy. But for Web 2.0 technology,
dynamic content and fancy visual effects can make accessibility testing very
difficult. This article introduces the WAI-ARIA standard, which is
designed to make future Asynchronous JavaScript and XML (Ajax) widgets
accessible. The article also covers accessibility
principles in Web 2.0 design and provides several code samples to get you
started.

Build Comet applications using Scala, Lift, and jQuery
Web applications have gotten more and more advanced, and users are always
expecting more out of them. One of the most advanced features is Comet, also
known as reverse Asynchronous JavaScript and XML (Ajax) or server-side push. Comet allows for browser-based instant
messaging, real-time stock quotes, and so on. Advanced Ajax libraries, such as
jQuery, make
it easy to write Comet applications on the client side, but getting them to scale
on the server is still a challenge. That is where the Scala programming language
and the Lift Web application framework can step in and deliver a scalable
back end for your Comet application. In this tutorial, build a
real-time Web auction using these technologies.

Localized client-side validation messaging using Ajax
When building a Web application that caters to users across the globe,
there are two points to consider: internationalized/localized page content and
validation of user inputs and message displays. While you can easily build an
internationalized version of the page using resource bundles (locale-specific
property files) on the server side, it is very difficult to display
internationalized validation messages when the validation is being done at the
client side. Using Asynchronous JavaScript + XML (Ajax) is one option to make
your life easier. This article discusses using Ajax and resource bundles
together to make the process of internationalized/localized client-side validation messaging
a little easier.

Create your own information space with Ajax and del.icio.us
del.icio.us is a social bookmarking Web site that allows users to create and
share browser-independent bookmarks, accessible directly over the Internet, in ways
your browser won't allow. The traditional hierarchical organization of browser bookmarks is overhauled, allowing users to instead associate each and every bookmark with any number of descriptive tags. Imagine a single page where you and your friends can surf the Web and have your del.icio.us tags, links, and functions handy, or a single page where you can save the site you're browsing directly into your del.icio.us account, along with comments and chosen tags. This tutorial shows you how to use Ajax to build just such a page using a PHP script as the server-side proxy.

Create an Ajax mindreader application with E4X and Prototype, Part 1: Build the Twenty Questions infrastructure
XML seems like a natural format for passing Ajax data. However, to work with
XML in JavaScript using the Document Object Model (DOM) is not always the best way to handle this kind of
data. This has given rise to other choices, such as JSON, which provide a more
object-like feel for developers. Now ECMAScript for XML (E4X) combines many of the
best features of the DOM with extremely easy data binding to provide a more
straightforward way to deal with XML in the browser. In this two-part article
series, you'll learn to use both E4X and the Prototype JavaScript library to create
a simple Ajax mindreader application that plays Twenty Questions and learns about new objects as it goes along. Part 1 shows you how to create a system that takes an existing knowledge base and analyzes it to determine what the user may be thinking.

Build a customizable RSS feed aggregator in PHP
RSS (Rich Site Summary, RDF Site Summary, or Really Simple Syndication) has
been around since the mid-1990s. Over the years, several variants of the RSS format
have popped up and several claims have been made about its ownership. Despite these
differences, RSS never ceased to serve its usefulness in distributing Web content
from one Web site to many others. The popularity of RSS gave way to the growth of a
new class of Web software called the feed reader, also known as the feed aggregator.
Although there are several commercially available feed aggregators, it's easy to
develop your own feed aggregator, which you can integrate with your Web
applications. You'll appreciate this article's fully functional PHP code snippets,
demonstrating the use of PHP-based server-side functions to develop a customizable
RSS feed aggregator. In addition, you'll reap instant benefits from using the fully
functional RSS feed aggregator code, which you can download from this article.
