The idea of JDojo is to bring JavaScript and Dojo to Java. To achieve this, JDojo provides Java stubs for existing Dojo and JavaScript types a compiler participant to the Eclipse Java compiler that emits JavaScript files for each Java file compiled The programmer does not program against the Java JDK classes, but against Dojo and JavaScript stubs that JDojo provides. The compiler participant only allows a subset of the existing JDK classes and also limits the Java language constructs that can be used. To support important features that exist in JavaScript but are not available in Java, JDojo provides Java annotations that the programmer can use to instruct the compiler how to translate code. While the compiler still produces class files, what is of interest is the JavaScript code. Only the generated JavaScript code is executable, the Java code is not. Contrary to Java-JavaScript cross compilers, JDojo does not add anything on top of the JavaScript and Dojo types. JDojo programmers program against the DOM, Dojo widget and other existing Dojo classes the same way as they would do it when programming JavaScript. Therefore, the Java code a JDojo programmer writes looks very similar to the JavaScript code he would have written. However, the programmer now can take advantage of a typed programming environment and benefit from the Eclipse Java Tooling. The translator produces JavaScript that looks as similar as possible to the Java code (without the types), and matches what a JavaScript programmer would have written. This is important when executing and debugging the generated JavaScript; it is still easy to understand the JavaScript code and map a bug back to the Java code. JDojo also fits nicely in the existing Jazz web bundles. JDojo code is placed in a new Java source folder, while the generated JavaScript is inserted in 'resources' folder that also holds existing JavaScript code. To use existing JavaScript code in JDojo, 'Stub' classes can be added, containing only th

"The Seam Framework - Next generation enterprise Java development Seam is a powerful open source development platform for building rich Internet applications in Java. Seam integrates technologies such as Asynchronous JavaScript and XML (AJAX), JavaServer Faces (JSF), Java Persistence (JPA), Enterprise Java Beans (EJB 3.0) and Business Process Management (BPM) into a unified full-stack solution, complete with sophisticated tooling. Seam has been designed from the ground up to eliminate complexity at both architecture and API levels. It enables developers to assemble complex web applications using simple annotated Java classes, a rich set of UI components, and very little XML. Seam's unique support for conversations and declarative state management can introduce a more sophisticated user experience while at the same time eliminating common bugs found in traditional web applications.

Some notes from a Mac OS X perspective: http://www.wuala.com/grahamperrin/public/2009/04/11/wuala.png for a screen shot of Wuala beta (133) on Mac OS X. http://www.wuala.com/grahamperrin/public/2009/04/11/wuala-nfs-finder.png for a Finder view of things; Wuala is presented as a volume. http://www.wuala.com/grahamperrin/public/2009/04/11/wuala-contextual.png shows a contextual menu for a PNG in Wuala. When I realised how well things are integrated, my jaw dropped. I was truly amazed. Uses of Java, NFS etc. seem to be excellent. I could wish for: * Wuala service to support extended attributes * the Wuala application to be more refined * an easier way to share/publish thumbnails of images - but these things are not show-stoppers. Summary: best in class! A winner!
