Steven Boscarine has written a nice short tutorial on getting up and running with Weld and JSF on Jetty, using Maven. Note that there's a bit more boilerplate here than there would be in a Java EE environment, since integration of Weld in Jetty requires explicit configuration. Nevertheless, I think Steven does a good job of demonstrating that it's easy to get up and running with this stuff.
Hot on the heels of the renaming of the Weld, I'm pleased to announce the 1.0.0.CR1 release. This is a major milestone; for the project and for Java EE 6, as it represents a feature complete implementation of the JSR-299 Proposed Final Draft 2 specification; the specification, implementation and TCK will be submitted to the JCP for the Final Draft ballot.
