A fast-moving Comet is about to impact the Internet. When it hits, it will wipe away the architecture flaws we have lived with for the past 15 years and allow a new World Wide Web to evolve. This new Web will include applications that are instantly on and always on, applications that are truly multi-user, and applications that go far beyond today’s “click and wait” Web solutions. Brace for Comet Impact Comet (or Reverse AJAX) introduces a significant departure from the stale “click-and-wait” interaction we traditionally associate with Web applications, and resurrects push-style communications – the 1990s technology that was long before its time. Comet introduces a more scalable, agile, and broadly supported approach to mixing push capabilities with the traditional REST-based communications model of the Web, one that also addresses the limitations that made the initia...

Super-Charge JSF AJAX Data Fetch

In our last article - "JSF and AJAX" (JDJ, Vol. 11, issue 1) - we discussed how JavaServer Faces component writers can take advantage of the new Weblets Open Source project (http://weblets.dev.java.net) to serve resources such as JavaScript libraries, icons, and CSS files directly from a Java Archive (JAR) without impacting the application developer. In this article we'll address the need to fetch data using AJAX with JavaServer Faces (JSF) components. The most common use cases for fetching data with AJAX are to populate dropdown lists and add type-ahead functionality in text fi... (more)

Apache Trinidad - A World Cup Skinning Experience?

One of the 2006 Soccer World Cup highlights must surely be the Trinidad and Tobago versus Sweden game. The underdogs Trinidad and Tobago managed to push off the onslaught from the Swedish team. The game ended 0-0, which was for the people of Trinidad and Tobago a divine experience - their teams very first World Cup point! So, you are, of course, asking yourself: What are these guys talking about? The question you should ask yourself is: Is Trinidad and Tobago going to be a success in the Java EE world as well? With the addition of project Trinidad to the Apache MyFaces community... (more)

AjaxWorld Special: Creating AJAX and Rich Internet Components with JSF

This article is based on, and contains excerpts from, the book Pro JSF: Building Rich Internet Components by Jonas Jacobi and John Fallows, published by Apress. Book is now available on fine bookstores and Amazon as of February 25, 2006. JavaServer Faces (JSF) standardizes the server-side component model for Web application development but doesn't standardize the presentation layer at the browser. In a series of articles we are going to look at how JSF can fulfill new presentation requirements without sacrificing application developer productivity building Rich Internet Applicat... (more)

AJAX and Mozilla XUL with JavaServer Faces

In our previous JDJ article - Rich Internet Components with JavaServer Faces - we discussed how JavaServer Faces can fulfill new presentation requirements without sacrificing application developer productivity building Rich Internet Applications (RIA). We discussed how JSF component writers can utilize technologies, such as AJAX and Mozilla XUL, to provide application developers with rich, interactive and reusable components. In order to use AJAX and Mozilla XUL with JSF, component writers have to make sure to provide any resource files need by these technologies, such as images... (more)
