In my endeavor to learn the JSF thing, I've started playing around with Facelets. So far so good. I've integrated into my existing MyFaces project. I did have some initial problems with the Facelets JARs to add to the project. I ended up only using jsf-facelets.jar, el-api.jar, and el-ri.jar. Seems really easy to use and I really like the templating support in Facelets; it's a definite improvement over Tiles.
