[jboss-as7-dev] mappedname behavior ?

Hi, I've started trying to use various examples about JEE5/JEE6 which all seem to use mappedname as Glassfish, Weblogic and recently Websphere is using it (as a name that can be used at both declaration and resource lookup time within the same module) I know that mappendname is left unspecified in the spec, but it seems most other JEE vendors have aligned (or at least seem to have aligned). Does there exist any forum threads and documentation (beyond the that outlines the reasons why JBoss EJB3 isn't aligning with what seems to be the consensus across the various servers ? I'm asking since it would make not only users but also tool developers life much easier if one could actually write and generate almost portable code ;) /max http://about.me/maxandersen
