Everyone,

Last night we finally got all the pieces to the dojo.E release finished and it is now online. There is quite a few things new in this release of dojo.E. We are also now making it possible to get the dojo.E code with the IMB, EDS and Nexaweb Server right from the dojo.E site.  This is exciting because you can get started with dojo.E and IMB by download a simple zip file.

I just presented a tutorial on Friday on using Direct Web Remoting, Hibernate and dojo.E.  It’s a very simple demo, but demonstrates the power of these three technologies combined to create simple, dynamic Java applications very quickly. The tutorial is available on SlideShare.

Note that there is a bug that obscures the URL for the SVN project.  The URL is http://source.nexaweb.com/svn/repos/trunk/tutorials/ajax/DWRExample/.

You can check out the project via SVN using this URL.

Also, to copy and paste the code snippets, download the document and open directly in PowerPoint. When copying and pasting, watch out for “smart quotes”. Some of the quotation characters in the PPT have been replaced with “smart quotes”, which are not recognized by XML parsers.

This will get even more exciting with the new features of DWR 3.0, which will add a RESTful layer to DWR’s remoting.  To learn more about DWR 3.0, I recommend Joe Walker’s presentation from The Ajax Experience last week.  He’s the lead developer for DWR.

Google Chrome is only about three weeks old and is already an Internet phenomenon. To sum it up, Google Chrome is all about making web browsing safer, faster, and easier. While some might see a fierce competition between Google Chrome and Mozilla Firefox, I see harmony.

Here is some background to better understand this point of view. There has been a somewhat valid belief stating that the un-typed and interpreted nature of the JavaScript language was a major limitation for building demanding client applications. Consequently, to overcome this challenge, the browser technology providers had the following two options:

1. Re-invent the language by “upgrading” the JavaScript language to a more a traditional typed and object-oriented language, such as Java or C#, allowing the runtime to just focus on running the code.
2. Re-invent the runtime by creating novels ways for the JavaScript virtual machine to parse and interpret the JavaScript code, making the language as robust and reliable as more traditional languages.

Just finished checking in the last of the updates (minus bug fixes) for the new Ajax IMB Client, after a week of straight coding and little else. The new version has been completely rewritten from the ground up. This coincides with Nexaweb’s upcoming release (in a month or so) of an updated version of the Ajax Client. The Ajax Client codebase will be completely updated and run over dojo 1.2. All the coding for these updates follow six principles:

The New Release: dojo.E 0.2.4

Last week the dojo.E team updated the code base of the dojo.E project. Many things in the code changed from the first release. The focus of the 0.2.x release was to create a well defined architecture around the core concept of adding XML to dojo. In this light, we created a flexible and well thought out XML processing engine that can take XML embedded in a script tag or external to the page and process the markup based on configured tag and namespace handlers.

Charting is one of the more advanced components that an application developer has at their disposal. It may not be used in every application but it probably could be and should be. Why? Charting makes the consumption of larges amounts of data easier and quicker than their tabular counterparts. In the Web world there are a couple of ways to bring charting to your Ajax application.

Over the last few months Nexaweb has been working on the dojo.E project and we just released the first version. dojo.E is designed to be a small JavaScript library that developers use in conjunction with the dojo toolkit. Completely open source the library is licensed under the Apache 2.0 license.

On Wednesday Nexaweb and HP came together to give a presentation on how to utilize their two platforms together. Why? Whether you are a back-end service provider or a front-end service consumer; the combination of governance and tools to make it easy to build applications provide an environment for best practice application development.

I attended this same conference exactly one year ago and the difference was pretty obvious: the way people are thinking about Ajax has changed dramatically. It’s something that I’ve been noticing for a while now, since I’m an avid reader of dozens of Ajax and RIA blogs and social news sites. But after talking to hundreds of developers literally 1 year apart, it was even clearer. Ajax is no longer being viewed as the “silver bullet” for the mess of problems that developing a web application creates. The hype and buzz is still there, but the expectations are a lot more realistic.

What is it?

HorizontalBoxContainer and VerticalBoxContainer is a pair of layout managers that allow multiple children components to be laid out either vertically or horizontally. This is similar to BoxLayout from the Java Swing toolkit.
