This brings the number of Web Profile implementations to no less than seven and the total number of certified platforms on the official Java EE compatibility page to eighteen.
GlassFish, WebLogic, Websphere, JBoss AS, and others provide full Java EE 6 platform compliance. Other Java EE 6 Web Profile-only platforms include Resin and Apache TomEE.
