It is important that portals can provide as easy a way of developing rich web applications as application servers do today.

Vaadin, representing rich web application frameworks, brings in an important view to the otherwise Java Server Faces (JSF) page-oriented ecosystem. Both kinds of applications are common in today's business world – one oriented more towards web sites and the other towards web applications, which Vaadin represents.

"Some actions such as changing the portlet mode today require a complete refresh of the page, making it very hard to create rich and interactive web applications in portals," says Henri Sara from Vaadin R&D about the challenges with the current Portlet 2.0 specification.

JSR-362 also concentrates on making sharing of resources, such as javascript, easier between portlets. Another goal is WebSocket support, and later on improving WSRP support. All things that portal developers and many of Vaadin's users are well aware of are challenging issues in portlet development.

"It is important that portals can provide as easy a way of developing rich web applications as application servers do today. We believe that having developed and maintained our own web Ajax framework for over 13 years, we have knowledge on the pitfalls in client-server communication," says VP of Vaadin R&D Artur Signell.

The group is lead by IBM's Martin Scott Nicklus and the work has gained considerable speed in the past few months. The progress of the group can be followed on the Java Community Process website at
