I have already got a list of Implementors who satisfy Sun's CTS for JEE 5 (http://java.sun.com/javaee/overview/compatibility.jsp ). I trying to find a comprehensive list of who is currently creating JEE 5 App servers and how much they are compliant. And whether these new versions have gone into production? If so, I would like to know the names of some of the big customers among them. Are there any players who are trying to comply just with EJB3 spec and not the whole JEE 5?
