Ajax for Java Developers: Java Object Serialization for Ajax

If you're doing Java Web development using Asynchronous JavaScript and XML (Ajax), then delivering data from the server to the client is probably your top concern. In this second article in the Ajax for Java developers series, Philip McCarthy walks you through five approaches to Java object serialization and gives you all the information you need to choose the data format and technology best suited to your application.

Ajax Performance Analysis

Asynchronous JavaScript + XML (Ajax) continues to raise user expectations for interactivity and performance, and developers are increasingly treating Ajax as a must-have component of their Web applications. As more code is moved client side and the network model changes, the community is responding by building more tools to address the unique performance challenges of Ajax. Examine toolsets that find and correct performance problems within your Ajax-enriched applications.

All Hail Shale: Shale Isn't Struts

What Shale isn't is a shrink-wrapped, well-documented, well-tested product complete with an automated installer and a polished management interface. Now find out what it is, as Brett McLaughlin unveils this mighty -- and rightful-- heir to the legacy of Struts. In this first of a five-part series, Brett explains what Shale is, how it's different from the Struts framework, and how to install and set it up in your development environment.

Avoid Unnecessary Ajax Traffic with Session State

Where possible, creating Web applications -- including Ajax-based applications -- in a RESTful way avoids a large class of bugs. However, a pitfall of REST (REpresentational State Transfer) is sending duplicate data across similar XMLHttpRequests. This tip shows how the moderate use of session cookies can maintain just enough server-side state to significantly reduce client-server traffic, while still allowing fallback to cookie-free operation.

Cross-Browser Web Application Testing Made Easy

'Test on multiple browsers' has been a mantra ever since there have been multiple browsers to test on. Testing them all--especially these days--is impossible. But you can come a lot closer than you may think. In this article, learn a variety of techniques for cross-browser testing, from the very thorough to the quick and dirty. The choice you make will depend on your resources, but this is an issue you can't ignore.

Curbing JavaScript Dependency

JavaScript can be used as an enhancement, but too often it ends up rendering a page unusable to people who don't run it. There are a number of good reasons why it might not be running in a given browser, and pages should never depend on it. MSG is a 'flavor enhancer,' with one slight problem -- some people are allergic to it. Most people don't seem to care much either way, but a small number of people seems to have bad reactions to it. If you ask people in the industry who sell it, they'll tell you it's quite safe, but there are others who claim that it's potentially lethal to some (very, very few) people.

Debugging JavaScript Using Venkman

Most people who do even a little bit of JavaScript programming, even those who are simply tweaking somebody else’s code, are familiar with the rudimentary JavaScript debugger in the recent versions of Internet Explorer. Click on the yellow warning icon in your browser, and you get a listing of various JavaScript errors in your code. It is simple, and for many people it is enough, but it’s not really the type of fully-fledged debugging environment with features programmers have come to expect in other development languages. If you find yourself doing a lot of JavaScript programming or tweaking and you are concerned with cross-browser support for your scripts, then Venkman is worth checking out.

Enhancing HTML Documents With ActiveX  

ActiveX is definitely a technology buzzword--but what is it, really? How does it work? Is it something that would benefit me as a writer? How can I utilize it? Technical writers are increasingly being called upon to combine new publishing technologies with writing skills. ActiveX technology provides new ways for writers to enhance their HTML documents with little or no actual programming involved. This workshop presents the various technologies associated with ActiveX, along with functional demonstrations. The goal of the workshop is to provide an overview of ActiveX that can serve as a starting point to further research and implement the technology.

Frameworks for Designers

These days, 'framework' is quite a buzzword in web development. With JavaScript frameworks like the Yahoo User Interface library, jQuery, and Prototype getting a lot of attention and web application frameworks like Rails and Django getting even more, it seems like everyone is using some kind of framework to build their sites. But what exactly is a framework? And are they only useful to programmers, or can we web designers benefit from the concept, as well?

Go Forth and API

To most, the virtues of Web 2.0 are rather ephemeral; that’s always been one of its main criticisms. However, I like to think that one of the movement’s key aspects is a sense of community, an ability to create sites and applications that bring people together.

jQuery Crash Course

As developers, we have more and more JavaScript libraries to choose from and, of course, the option not to use any at all. Over time, we each tend to favor one method of coding over another. For those who'd like to learn more about jQuery, one of the more popular libraries, here's a crash course written with code-savvy web designers in mind.

Make the Best Use of Asynchronous Callbacks

It takes some finesse to make the best use of asynchronous callbacks for Ajax data sources in JavaScript applications. This tip discusses why you should use asynchronous callbacks for Ajax data sources and gives examples of coordinating the readiness of mutually dependent application data sources that may become ready at undefined times with asynchronous calls.

Performance Ajax Tools

Wasting server resources can impact the performance of Ajax applications, resulting in excessive HTTP requests, high memory consumption, and the need for an unusual amount of polling to make applications work. Regular developerWorks author Judith Myerson suggests some open source tools and Firefox add-ons you can use to improve or solve problems with your Ajax applications.

Programming Web Services with SOAP

The task of creating and deploying web services is really not all that difficult, nor is it all that different than what developers currently do in more traditional web applications. The tendency on all platforms is to automate more and more of the gory details and tedious work in creating web services. Most programmers don't need to know the exact details of encodings and envelopes; instead, they'll simply use a SOAP toolkit such as those described here.

Set up an Ajax Environment With a Scenario

Ajax (Asynchronous JavaScript + XML) is quickly emerging as a modern way of bringing desktop-quality software features to Web applications running on browsers. Open source software such as Linux-Apache-MySQL-PHP (LAMP) and open standards-based J2EE middleware, such as WebSphere Application Server Community Edition, provide excellent capabilities to develop and deploy Ajax Web applications.

Speed Up Your Ajax Applications While Dodging Web Services Vulnerabilities

Deploying bandwidth-efficient Ajax applications does not guarantee that the service levels in a Service Level Agreement will stay high. No matter how well you change code in the Ajax format to make it more bandwidth efficient, there will be always risks and vulnerabilities you'll need to watch out for and mitigate. Regular developerWorks author Judith Myerson gives a brief Ajax recap, shows what Web services vulnerabilities are and why Service Level Agreements (SLA) are important, and suggests some solutions for speeding up Ajax applications.
