After an intensive month of work i’m back to my blog to give you what i learn. My actual project concerns embedded systems with tablet PC. Then i had to use Bluetooth in Java. After i read a few articles, using this technology is easy. The problem is to find the an implementation. The JSR 82 is recent and there’s not a lot of open source implementations. I choose 2 which worked great and use the Windows Bluetooth API : BlueCove and BlueSock.

oct
Hello All,
I’m glad to announce the release of Rialto-GWT
RialtoGWT is a wrapping of the Rialto javascript library to use with GWT.
We decide to start this wrapping cause we see here a mutual interest:
For the Rialto Community which can use the GWT development framework
to easily write and deploy Rialto application
For the GWT Community which can use the rich widgets and behaviors
offered by the Rialto Framework.
You can find the project home page here
The source can be download here
You can find some tutorials here

JFXBuilder

Based on the great report designer tool : ReportMill, JFXBuilder is the first Java rich interface designer. A « preview JFX » button transform the ReportMill shapes in the JavaFXPad with the corresponding JavaFX Script. It’s just a first version with bugs but the concept is interesting and the based tool have already prove his reliability.
Java on the RIA road

The JavaFX news have burned feed readers, Sun take place on the RIA market against Microsoft and Adobe and it’s a good thing. F3 (i talkin’ about before) which is the base of JavaFX Script is a very great technology, and make easier the Swing productivity in terms of design. But don’t forget Java have always been a RIA plateform with Applet to create RWA applications. Apple understand this and migrated NeXT UI library since WebObjects 5.0. Java Web Start was arrive after making easier, like Web application, the deployment of RDA applications. Sun was in advance in this domain but Applet don’t find success and it’s the asset of Silverlight and Flex because they have GUI design tool (Expression Web, Flex Builder). Bob Brewin Sun CTO, tell us that this tool is a priority [Ed Burnette interview Q6] : JavaFX Designer.
I’m not agree with Simon Brocklehurst, I think that this tool and the designer/developer collaboration are essential, i’m not saying developers aren’t good designer, i think application conception with clean code is an art but design and development are different jobs.
The other difficulty is the JRE size, ~13 Mo where the others turns around 5 Mo, but it will be better.
Finally don’t forget mobile objectives (JavaFX Mobile), Java is really present in this domain and could make the difference.
Chris Oliver don’t choose XML for JavaFX Script unlike Microsoft with XAML. It’s true that JavaFX Script syntax is more intuitive and have advantages but we loose XML extension advantages (XInclude, XPath, XSLT). I was thinking Sun make more interest on JAXX, an XML UI language for Swing. But it’s a reality that JavaFX Script is an easier syntax for UI design.
What about SWT ? Bob Brewin say JavaFX Script could be extended for SWT [Ed Burnette interview Q5], and SWT is going to be compatible with WPF, could we have SWT UI generated with XAML ?
Don’t forget SWT is an UI library for RDA not RWA. The Silverlight, Flex and JavaFX Script objectives aren’t the same than Eclipse RCP, NetBeans RCP, Apollo and WPF. I notice that Silverlight use only 30% of WPF [5mn avec Kevin Gallo, Product Manager Silverlight par Didier Girard] where JavaFX Script can use all Java libraries.
What’s interesting thing is Eclipse is everywhere :
- Flex Builder is based on Eclipse
- Plugin JavaFX Script
- Eclipse on WPF
- Eclipse on Swing
When you choose Eclipse you’re sure make the good choice 
.
To compare JavaFX Script and XAML the pad tool are interesting :

After thre great WPF demo, it’s the Java moment to do it : turn pages of book. It show the Sun and Swing team effort to not get left behind Microsoft on UI.
Sun Java Tech Days Paris / JavaDB

Nothing new than the Prague‘s session in november. I went a new time to see James Gosling, we can’t see him very often in france. His presentation wasn’t really wonderful but its interesting to have his viewpoint of actually java technology. I took the opportunity to see the session i missed last time in particular JavaDB after i have seen the François Orsini‘s demo. The use of JavaDB is very interesting, the demo was on a web application and i hope i can migrate my desktop application with this techno to have now a real rich client application which integrate a disconnected mode. So, to be continued …

Robert Cooper and Josh Marinacci just reveal their AB5k project. A « widget container », like we can see now on Vista and had already on MacOSX, to integrate on our desktop a calendar, the weather of the day, last news of the world … In Java 6 and cross-platform.
OSGi demo

Neil Bartlett and Alex Blewitt gave a demonstration to JSig on the benefits of the OSGi platform for dynamic Java applications. It show us the basics of this spécification whith a few demos. OSGi is a great new technology. Eclipse choose it yet (Equinox), and the Spring OSGi framework give us the possibility to integrate this correctly in our applications.

Cayenne in the Apache incubator

Cayenne is now an Apache top level project. This ORM framework inspired of Apple EOF is a serious Hibernate concurrent and is best approach for desktop application. EOF architecture which is in Cayenne is robust, if the community grow this project could be the first Hibernate concurrent. The 3.0 implement the JPA specification.
