Portlets in the light of OSGi and other technologies
Initially, it was hard, if not quite impossible, to use everyone preferred web framework with portlets because a bridge was needed, and very few bridges were available! Then, portlets have been quite a little bit deprecated due to AJAX appearance, as initial portlets were just like hor...

How To: Visual JPA with Ajax Push
Bilal Ahamed has put together a tutorial on Using Java Persistence API in a Visual Web ICEfaces framework and NetBeans including Ajax Push. An interesting variation would be to try the SessionRenderer in this application (instead of the RenderManager APIs that were used). So in init()

JavaOne 2009 is Dead. Long Live JavaOne.Next: Part 2
After the Java Champions, I stayed only half hour for Java User Group Leader BOF to listen in. Many JUG Leader wanted to get information on how to get more speakers to their events. They asked questions on whether JUGs should hold regularly attendance on fixed dates? (The JAVAWUG does not, be...

Pro JSF and Ajax feedback
It is now over 3 years since John and I published our book - Pro JSF and Ajax - and a lot of things have happened since then. At the time of authoring the book we were both employed by Oracle working in the Oracle Application Server division - an excellent experience with fantastic colleagues! B...
Ajax vs JavaFX
GlassFish now also boots via JavaFX rather than OSGi. Just press the play button, and GlassFish modules from the individual keyframes start up in sequence. EJB and Asynchronous Servlets have new sound effects that can be dynamically loaded from the update center.

On the road to ICEfaces 2.0
Although ICEfaces 1.8 currently runs on JSF 2.0, it doesn't make use of many of the new features (but it is a good demonstration of the backwards-compatibility of JSF). To really take advantage of JSF 2.0, it is necessary for ICEfaces to leave its JSF 1.1/1.2 legacy behind. You can find the beginni...

Ajax Push is Easy
Building Ajax Into the Web Today we implement Ajax in JavaScript, but it is natural to consider incremental page update as an inherent part of the web. Rather than returning a full page response to a form POST, the browser could directly accept an edit list for the current DOM and apply it aut...

Opinion: Looking at Eclipse Plugin Jupiter Again, After a Year with Crucible
In going back to Jupiter, all my problems with it are the user interface, and it does not appear to have changed much. I was thinking this project was dead, but then I went and prodded it and saw that there are actually signs of life: releases, a blog, etc. However, either no one has gotten to the a...

SmartGWT 1.0 Released!
DataSource's can be made to point to local or test XML data for rapid prototyping and later be changed to point to a server and everything will continue work the same way. The XSD DataSource sample illustrates how you can read a DataSource definition for a server using a standard XML Schema.

Why not using JavaScript as a scripting language, but outside browsers !?
The availability of Mozilla JIT compilers gives new opportunities to use JS outside browsers. This raises at least 4 points, for short-term or long-term. 1) Why not packaging and releasing separate JDK and JRE (here, J is for JavaScript), that is, out of Mozilla releases ?

HTTP Proxy Servlet for Ajax Calls with Authentication Support

Snappy Calendar and Table components for ICEfaces
There are many dimensions to Ajax, yielding many different possible approaches. One particularly interesting dimension is the division of labour between client and server. Generally, ICEfaces assigns the most work to the server, treating the browser as a remote display. There are a num...

Opinion: Remember The Milk : One of my fav Ajax applications
For those not familiar with Remember the Milk, it is a to-do task management app. However it's not just another todo app - it is an extremely well written app that truly encapsulates the essence of Web 2.0 and has been one of my favorite Ajax apps from the time they first launched in 2005. They wer...

Ajax Push in Real Time?
Of course, it's not actually necessary that the page updates arrive at each client at exactly the same time, just that they arrive within some short interval. In the past, I have objected to applying the term "real time" to Ajax Push on the web. Real time systems typically are used to control p...

Ajax Pushed at fisl9.0
Here I am, showing WebMC on the iPhone. The trick to giving web-based demos on the iPhone (when the server is on your laptop and a WiFi network may or may not be available) is to enable connection sharing on your Mac (even if you don't have a connection to share). This works much better than creat...

jWebApp is extreme in its ease of use, and is perfect for Agile (Rapid) Development!
If we were to ask ourselves “what are we actually doing with a web application”, the answer would be something like “we are associating application code with a web request”. Putting it another way we are associating application code with a URL and an HTTP method (GET or POST). So, in the end, a...

AJAX with Yahoo UI components and DWR
I've been playing lately with YUI, the Yahoo User Interface library. So far I've used the autocomplete and treeview components, and I have to say they are quite easy to use and very complete. I had used Script.aculo.us autocomplete before, but YUI autocomplete has a lot of configuraiton opti...

Opinion: My "Ajax Experience"
JQuery : JQuery is really slick. Its lightweight, powerful and has a very intuitive API. Unlike Dojo or Ext, JQuery is a library and not a framework and typically targets different use cases. Dojo or Ext are probably not the best choices if you want to sprinkle some Ajax magic on some of your int...

Adding Ajax to a Spring App
I work on a Spring-based web application that is fairly data-intensive. It originated several years ago and had to support some pretty old browsers for the time (back to IE 5.5 and NN 6.something, as I recall). This app has had minor UI facelifts since but nothing too major. There are a couple of a...

Opinion: JSON creator slams Ajax, Web, Why???
This left JavaScript and then XMLHttpRequest for communicating from the browser to the data server. "It was really Microsoft that created all the components that Ajax needed," Crockford said. Crockford then went through a critique of various Web technologies.

Layered Ajax Security
Finally, the nondeterminism of dynamically loaded scripts make the complete Ajax system difficult to analyze from a security perspective (what cannot be analyzed is potentially a security risk). When data is passed to the browser as JSON rather than XML, even the data is dynamically ex...

The language for Ajax with ICEfaces is JSF
One of the central themes of ICEfaces is the language that the developer and designer use to define their Ajax application. The important point is that it has nothing to do with Ajax at all. Ajax should be transparent, with development and design taking place at the right level of abstractio...

Ajax in Spring Web Flow with ICEfaces

Taming AJAX with GWT, by Scott Blum I switched to this presentation at the last minute, and am quite glad I did. GWT is a toolkit to help you write JavaScript and event-driven AJAX. The prime difference between this and others is that you write in Java.

What is AJAX?
The underlying theme of AJAX is for web applications to break out of the form submit/response pattern. They're asynchronous because the user isn't synchronized with the HTTP protocol. They use JavaScript because that's the only way to efficiently control a web browser. They use XMLHttpR...
