[Building Sakai] Is it possible to use JSF 2.0 in new Sakai tools?

[Steve Swinsburg]

Hi Tiago,

If you are looking at doing lots of AJAX and want to develop in a Java based framework, I'd highly recommend Apache Wicket. You can perform AJAX from pure Java using the Wicket framework.

It also seamlessly integrates with Spring and Hibernate, and there are dozens of extensions and components built for it. It has a large community behind it and it actively developed and maintained. You might find the components are built for you already if you check on the Wicket user mailing list.

In the upcoming Sakai release, several tools are Wicket baed (Profile2 and SiteStats) and both are rich AJAX applications - there are more Wicket based tools in the contrib space also.

Info about Wicket: http://wicket.apache.org/
Info about some of the community extensions: http://wicketstuff.org/wicket14/ajax/

Considering this is a new tool, I would advise against JSP and JSF for the reasons outlined previously, but also due to the lack of separation between code and presentation.

cheers,
Steve

That framework offers a markup language called ZUL and alternatively all components in JSF or JSP format. Sakai also offers JSF and JSP support, so in order to provide an uniform approach, we are choosing between JSF and JSP.
