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.

"Apache Tapestry is an open-source framework for creating dynamic, robust, highly scalable web applications in Java. Tapestry complements and builds upon the standard Java Servlet API, and so it works in any servlet container or application server.
Tapestry divides a web application into a set of pages, each constructed from components. This provides a consistent structure, allowing the Tapestry framework to assume responsibility for key concerns such as URL construction and dispatch, persistent state storage on the client or on the server, user input validation, localization/internationalization, and exception reporting. Developing Tapestry applications involves creating HTML templates using plain HTML, and combining the templates with small amounts of Java code. In Tapestry, you create your application in terms of objects, and the methods and properties of those objects -- and specifically not in terms of URLs and query parameters. Tapestry brings true object oriented development to Java web applications. "

"Stripes is a presentation framework for building web applications using the latest Java technologies. The main driver behind Stripes is that web application development in Java is just too much work! It seems like every existing framework requires gobs of configuration. Struts is pretty feature-light and has some serious architectural issues (see Stripes vs. Struts for details). Others, like WebWork 2 and Spring-MVC are much better, but still require a lot of configuration, and seem to require you to learn a whole new language just to get started."
