The only problem occurs when they fail to have network access. This is when an offline feature is necessary. Apache Derby is a great option for enabling offline access to Ajax-powered applications. Learn how to use Apache Derby as a local data store that can be used to take your Ajax application offline. http://tc.eserver.org/32553.html http://tc.eserver.org/32553.html I will go through how to make a full-blown widget that uses AJAX technology. It fetches news from a newsfeed source, presents them nicely to you, includes some eyecandy and of course lets you customize the amount of news items, refresh time and which category of news you want to be shown. http://tc.eserver.org/32006.html http://tc.eserver.org/32006.html Slicken up your web apps with these tips and tricks using the Yahoo! User Interface library. http://tc.eserver.org/32003.html http://tc.eserver.org/32003.html 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. http://tc.eserver.org/31637.html http://tc.eserver.org/31637.html 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. http://tc.eserver.org/31638.html http://tc.eserver.org/31638.html 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. http://tc.eserver.org/30661.html http://tc.eserver.org/30661.html 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. http://tc.eserver.org/30658.html http://tc.eserver.org/30658.html 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. http://tc.eserver.org/30669.html http://tc.eserver.org/30669.html 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. http://tc.eserver.org/27053.html http://tc.eserver.org/27053.html 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. http://tc.eserver.org/27054.html http://tc.eserver.org/27054.html Implement a Web browser-based SOAP Web services client using the Asynchronous JavaScript and XML (Ajax) design pattern.
