It's tempting to rationalize the differences, but as the one who pretty much created both (I was very active in the EJB 3.1 JSR) I can say they are the same with one tiny difference. A slight variation in classpath scanning. For that slight difference and not wanting to break all the existing users, we left 3.1.x alone. The OpenEJB trunk code (4.0.0) uses the EJBContainer API and not the InitialContext technique. In terms of vendor implementation speed, that's a different story. In GlassFish's defense, the Java EE spec itself can't close until GlassFish is "finished" because it's the RI. So a lot of things that they'd really like to spend time on just have to wait till after the final release. No doubt this was one of them and I'm sure that part will speed up at some point in the future. > Thanks OpenEJB ppl, examples are often worth their weight in gold!
