We need to work with the AS team (Patrick M/Fnasser) to get access to the JBoss EWS they want us to certify against. Ultimately good if we can get EWS QA involved to participate verifying they work well.
As EWS is a Tomcat (and apache, but that is not relevant for us, beyound possible using project archives) don't expect to Seam work out of box on it, but being able to deploy plain War, some JSF apps etc. is expected to work.
