A year ago, a few of my colleagues and a small team assembled over seas started a github project to wrapper DojoToolkit into standard JSF 2.0 widgets. We actually got pretty far before having to move on to newer projects - like IBM's new Worklight acquisition or in my case into a whole other division of IBM - Smarter Commerce.
If you would like to take a look at the work we did, please check out our github project here: https://github.com/kennas/DojoServerFaces.
The project includes samples and such including a widget gallery so you can quickly see how many widgets we were able to wrap. Here is a great article that was originally written on the WAS Web 2.0 and Mobile blog site: Bring JSF and Dojo Together With DojoServerFaces .
I know it has been a while since there has been any code committed, but if anyone has an interest in helping further its development, please send me a request via github. We can see if there is enough public interest to get this project started again! Dojo has some really nice content, and it would be great if we could keep a JSF widget library up to date with its latest.
