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.

Over the weekend the dojo.E team spent some time at the Dojo Foundation’s Boston Dojo Developer Day and then at The Ajax Experience with some cool swag in tow. For those who missed these events, we’re giving away free stickers along with a limited number of t-shirts at the dojo.E website. Hurry up, though, as supplies are limited.

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:

One of the goals of the dojo.E project has been to bring some of the standards created by the W3C and others to developers for building their Ajax applications. A couple of weeks ago, I saw on Ajaxian.com that Firefox and Webkit are going to support XBL. Simply defined, the XML Binding Language or XBL is a way to create reusable components.

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.
