A cross-browser DHTML table
The HTML table tag allows users to organize content in a Web page efficiently and in an easily readable form. However, this tag has limitations if you want to do something more than just display the data. You can use Java applets, but they take forever to load and are cumbersome. In this article, Shelley describes how users can create a cross-browser table with DHTML and JavaScript, which does most of the things that a table component written in Java might do.

A multi-tier architecture for building RESTful Web services
RESTful Web services have emerged as a promising alternative to SOAP-based
services due to their simplicity, lightweight nature, and the ability to transmit
data directly over HTTP. In this article, get an overview of the concept of REST and
RESTful Web services, and compare them to RPC-style/SOAP-based Web
services. You'll also learn about Java frameworks for building RESTful Web
services as well as a shared multi-tier architecture for building both
RESTful Web
services and dynamic Web applications.

Access unusable log data with SQL
Application output logs create a very real dilemma. The logs can have too much output and be unmanageable, or too little output and be useless for tracing real problems. Developer Sam Mefford demonstrates that logging to an RDBMS can eliminate this problem, turning unusable output into informative reports. This article illustrates that by using SQL as a mining tool, data worth is greatly enhanced by revealing details of application usage, highlighting code fragments and queries that need optimization, and pinpointing the conditions that create hard-to-reproduce bugs.

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.

Adaptive user interfaces for health care
applications
Adaptive user interfaces assist users in accomplishing tasks in an
application and construct a model of the user's preferences so as to serve them
better in the future. Examples include systems that filter news stories, recommend
products, and so on. This approach to personalized services is relatively new but has
great potential for improving the effectiveness of human-computer interfaces.
Health care is a significant area where adaptive user interfaces can be of
great use. Health care users range from having little computer knowledge (for
example, some
nurses or doctors) to having expert computer knowledge (for example, system administrators).
And, there can be many other distinguishing factors when it comes to patients.
Therefore, adapting a computer application's interface to different types of users is important to
improve the usability of such applications. Two major techniques used for
adaptation are adaptive presentation and adaptive navigation. Adaptive
presentation involves personalizing the contents presented to the user.
Adaptive navigation involves customizing ways by which users complete their
tasks in the application. These techniques can be used to enhance the
usability of health care applications, thereby contributing to their
success.

Ajax and REST, Part 1
The more that server-side Web applications become immersive by following rich-application models and delivering personalized content, the more their architectures violate Representational State Transfer (REST), the Web's architectural style. These violations can decrease application scalability and increase system complexity. By achieving harmony with REST, Ajax architecture lets immersive Web applications eliminate these negative effects and enjoy REST's desirable properties.

XML Matters: Ajax tradeoffs: The many flavors of XML
Ajax has become a familiar acronym for many Web developers these days, but it combines several very different techniques. One is the in-page manipulation of the DOM tree that was formerly known as Dynamic HTML. Another is the passing of data back and forth between the client and the server behind the scenes, without re-loading the page. The combination of these can make powerful Web applications which have many of the desirable features of desktop applications. The focus for now will be on just one group of related aspects: what format should the data exchange take?

Java theory and practice: Are all stateful Web applications broken?
The session state management mechanism provided by the Servlets framework, HttpSession, makes it easy to
create stateful applications, but it is also quite easy to
misuse. Many Web applications that use HttpSession
for mutable data (such as JavaBeans classes) do so with
insufficient coordination, exposing themselves to a host of
potential concurrency hazards.

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.

Real Web 2.0: Bookmarks? Tagging? Delicious!
In this article, you'll learn how to work with del.icio.us, one of the classic Web 2.0 sites, using Web XML feeds and JSON, in Python and ECMAScript. When you think of Web 2.0 technology, you might think of the latest Ajax tricks, but that is just a small part of the picture. More fundamental concerns are open data, simple APIs, and features that encourage users to form social networks. These are also what make Web 2.0 a compelling problem for Web architects. This column will look more than skin deep at important real-world Web 2.0 sites and demonstrate how Web architects can incorporate the best from the Web into their own Web sites.

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.
