PeterJ, Thanks for the information. I was unaware the Java EE 5 certification implied compliance the the list of JSR's in the link. That does answer many of the questions. Is there anything that JBoss supports that is not implied with EE 5 certification? For example, I remember seeing documentation regarding single sign on and federated identity(JBoss Federated SSO). SAML support was listed, but not which version. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217088#...
