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.
I am starting to move all Drools5 integration code to the Seam 3 drools module and will update the previous posts with correct links as soon as they are available. There will be no further development against the Seam 2.2.Drools5 branch.
