Back in consulting I did some small projects using the Pushlets framework. A nice and simple solution to create easily Web eventing applications...

The Pushlet team has created a small demonstration of integration of Pushlet and XMLHttpRequest together...

If you never used Pushlets, take a look to it it is really nice!

The JSR-198:A Standard Extension API for Integrated Development Environment expert group has made the early draft available for review.

I really love this JSR and I am very happy that is now making progress because I played around in the past with Oracle JDeveloper Plugin APIs and I was disappointed that my work could not be used in other IDE...

Oracle JDeveloper 10g (10.1.3) API will be based on the JSR 198. Take a look the Oracle JDeveloper Extension page.

On my side I have to dig out the old extensions that I wrote for 9.0.3 and migrate them to 10.1.3, I will start with the small Lejos extension, if I can find it... It has been so long since I did not play with my legos...

Michael Maheomff has published on AjaxPatterns Web site an article that list existing Ajax frameworks. This AJAXFrameworks article talks about server side solutions (Java, PHP, .Net, Lisp, Ruby, ....) and client side solutions that provided helpers around XMLHttpRequests and HTML programming.

Feel free to let some comments to Michael on its wiki if he has forgotten some... for example nothing about JavaServer Faces...

Today is an important day. We’ve got some great stuff for you today.

Here we go, WWDC 2005 has started, and as usual it is hot! You can have a summary of Steve Jobs' keynote on Macworld Web site.

I think the most breaking news, beside the good numbers is the confirmation of the fact that "Apple drops IBM PowerPC line for Intel chips"... What do you think? I am personally happy; this will stop the 'useless' discussion about the speed of the chip of PC versus Mac... and, I am optimistic on the fact that Macs will be faster ;-) For me the chip is not important since the only code that I write on Mac is Java based, and little bit of AppleScript...

I am impatient to see the new stuff that Apple will put in Leopard...

Once again a rumor of Apple switching to Intel is making some noise on the net....

We won't have to wait for long since the news talks about Steve Job announcing that during his keynote at WWDC. I am currently planning to buy a new powerbook 12" (in addition to the 15" and iMac)... who knows, it may be an "Intel Inside" one ;-)

The other fun part is the deal that IBM is trying to obtain with game platform.. such as Sony and... MSFT...

We'll see tomorrow... Talking about WWDC, Oracle has a booth and some presentations for this event... I will be personally working on the pod presenting Oracle 10g stack on Mac OS X... See you this week !

With all the Java Scripting language around (Groovy, Rhino, Ruby, Jython... and so on) it is always interesting to understand where this come from... but also be able to talk with people about it, especially when they do not understand why scripting is interesting...

Googling around looking for some information on scripting benefits for a presentation I found this very intersting article from John Ousterhout, (he wrote the article in 1998) but I am sure you will still appreciate it...

Scripting: Higher Level Programming for the 21st Century.

One of the most interesting part in this context is the paragraph 4:

A scripting language is not a replacement for a system programming language or vice versa. Each is suited to a different set of tasks. For gluing and system integration, applications can be developed 5-10x faster with a scripting language; system programming languages will require large amounts of boilerplate and conversion code to connect the pieces, whereas this can be done directly with a scripting language. For complex algorithms and data structures, the strong typing of a system programming language makes programs easier to manage. Where execution speed is key, a system programming language can often run 10-20x faster than a scripting language because it makes fewer run-time checks.

Finally the Java specification about Web Service will have a name that makes sense... moving away from JAX-RPC to JAX-WS (JAX Web Services)...

The JAX-RPC name, which stands for Java API for XML-based RPC, is misleading because developers assume it is only about RPC, according to Doug Kohlert, a Sun staff engineer, in his blog this week. “By renaming JAX-RPC to JAX-WS, we can eliminate this confusion,” Kohlert wrote. JAX-WS stands for Java API for XML Web Services.

This infoworld article will give you more details.

I am sure you already heard about AJAX, the "new" way of building Web application where using HTML, Javascript, DOM, and XML you can  build very interactive Web applications, some examples of this interactivity are Google (suggest, local, mail), MSN, Amazon, .....

If the term  Ajax is relatively new, the technologies used are quite old now. And you do not need anything new to be able to leverage this approach in your current development, and since it is mainly a client (browser) based technology this can be used whether you develop your application in Java, PHP, or or even PL/SQL for the Web. In the same time, you do not want to have to develop too much of the client side to handle user interaction, this is where new frameworks that provide support of this technologies, let's say AJAX based, are very interesting. It is now possible to create very interactive Web application without passing 80% of your time in the client side development - that could be generated from your server obviously.

In the same time, before adopting such framework, it is important to understand what is happening. This is why I am creating this quick introduction based on 2 simple use cases:

  • loading message:  you often want to provide some feedback to your user when your browser is processing some data
  • dependent lists: how you can easily create dependent lists, in lot of application you want to drive a selection list from another
