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... (more)
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 available on fine bookstores and Amazon.
In our previous article - "Rich Internet Components with JavaServer Faces"
(JDJ, Vol. 10, issue 11) - 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
Can a client-side AJAX solution and server-side Faces solution co-exist and
play well together? Or are they each solving a similar problem in a different
and incompatible way? The authors of Pro JSF and Ajax, Jonas Jacobi and
John R. Fallows, will discuss how the JavaServer Faces framework can be used
to embrace AJAX today, while protecting Web applications from radical
re-architecture each time there is a change in direction of client-side
technology. Jonas and John will address the key aspects of Faces component
development, and will introduce innovative techniques to adopt AJ... (more)
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
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)
This is our last article in a series of four that have been introducing the
concepts of creating AJAX-enabled JavaServer Faces (JSF) components. In this
article we are going to summarize and encapsulate the concepts that were
introduced in the three previous JDJ articles starting with the "Rich
Internet Components with JavaServer Faces" (Vol. 10, issue 11), and design a
Google-like JDJ InputSuggest component.
We will show you how to use Mabon to create a simple and powerful input
component with built-in suggest functionality similar to what Google Suggest
provides. To make it ea... (more)
