Hibernate Validator 4.0.1 is now available and can be downloaded from here. This release addresses issues discovered by the JCP integration efforts for JSR-303. Of course we used this opportunity to also fix some bugs identified by the community. Thanks for all the feedback.
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.
