From a technical standpoint Ext GWT and SmartGWT are quite equal apart from the fact that Smart has more to offer on the server side. Vaadin with its complete different apprach (not from the programming style but from runtime behavior) needs to be compared in a different fashion. Things like GUI responsiveness and overall performance must be carefully checked. But on the pro side you have a very small js client with vaadin which results in fast startup in the browser. On the other hand, our product is a business product and we are planing to rewrite the AdminConsole. This is something that will be used in intranets in 95% of the time. It doesnt make much of a differnece if you load 100k or 1Mb from inside the LAN.

Special thanks to Piero Sartini who came up with this alternative. It is basically the same as the previous alternative, but it uses the new JEE6 Context and Dependency Injection (CDI) and session scoped beans instead of EJBs. This alternative should have better performance than using EJBs. Instead of annotating the Vaadin application as a stateful session bean, it should be annotated using the @SessionScoped annotation, like so:

In this article, we are going to look at how the Activiti BPM engine can be used together with Vaadin. We are going to do this in the form of a case study of a demo application that is available on GitHub. The code is licensed under Apache License 2.0 and can freely be used as a foundation for your own applications. Before continuing, you might want to check out this screencast of the demo application in action (HD quality is recommended):

Icefaces is an open source Ajax framework for developing RIA for the web. The applications are structured the same way as JSF applications, but with added Ajax features. In this article there will be a short description of the biggest differences between the IT Mill Toolkit 5.2.0 and Icefaces 1.6.2 based development of RIAs.
