2004-05-07 TSSS: EJB 3.0 Work in progress (from Jason Carreira's weblog) EJB このレポートが一番詳しいかな。要するにIoCベースになってコンテナが「消える」ということ? CMP will be simpler, with a POJO approach. It will even support new() for creation. They're going to support inheritance and polymorphism and object-relational mappings. ほほぉ。CMPはだいぶ改善されそうですね。
