Some people are discussing the future of the JCP currently. But the builders of Java EE Application Servers are still using its outcome bravely, currently working more than a year on those products, that will be compliant and certified towards Java EE 6, a standard that is with us since 12/10/2009.
Since December 28, 2010 JBoss 6 is out there, although the newstickers were not as loud as in good old Marc Fleury times when for instance some 6 years ago the J2EE 1.4 release was announced and they used to be the first (open source) one. And reading carefully, JBoss 6 is currently not “Java EE 6 certified” but “a fully certified implementation” of the Java EE 6 Web Profile specification, and this is quite a difference. A comment from Bill Burke might be read like: OK, there will be a Java EE 6 certified JBoss EAP 6 (JBoss 7 in it) by the end of 2011, as long as you pay for that.
Not only will JBoss no longer be the first certified open sourced one,
but there will be no more certified JBoss "free as in beer server" at all.
Another speculation about the status and speed of the rest of the pack like Resin 4, WebLogic Server 11g R2 (from Oracle), WebSphere 8 (from IBM) or Geronimo 3 can be found here.
