Select "ejb3" profile when using installer. Latest installer drop is 1.2.0BETA1 (http://sourceforge.net/project/showfiles.php?group_id=22866&package_id=193295). It includes AS 4.0.4GA, EJB3 CR8, and jbossws-1.0.1.GA which supports JSR-181.
While looking for a way to get jbossws 1.0.1 installed I was reading your post again. It seems as if jbossws 1.0.1 is not part of the 1.2.0BETA.
However something must have changed because the file now downloadable is bigger than the file I downloaded some days ago. Can you tell me what changed?
