Rod Johnson's interview on TSS
RJはEJBを批判しつつも良いアイディアは認め、それをAOPで実現しようという考えです。彼は「EJBはAOPフレームワークへ至る過渡的な解だ」と前から言っています。
I think that EJB is a transitional solution to AOP middleware. I think AOP generalizes a lot of the ideas that we successfully applied in EJB, and makes them both more powerful, but eliminates a lot of the downsides of EJB.
