J2EE is our bread and butter. We will still be improving our J2EE implementation and strictly following the J2EE specifications.

Or are there plans to That's your perogative. We want to be leaders for once and not followers. I think our approach is going to be revolutionary and we will become our own standard. We're in this for the long haul and not just for the lifespan of these clunky specifications that are designed by committee. I saw CORBA stagnate because of the political OMG committees. IMHO, J2EE is now suffering from this as well. DCE, CORBA, J2EE were all fine iterations the Nirvana of distributed computing. Its time to innovate and iterate again. > make this, for example, JDO-like? > I'm not sure what the persistence layer will look like. We're hoping that the AOP framework and the new persistence engine design will allow us to look like anything, but those are high naive hopes. There's also been talk about being JDO-like, but you'll have to go on the persistence development forums to find out what's going on. > Will it also be possible to use a POJO as a session bean which > has the same > capabilities?

You'll see soon. The whole industry will be moving in this direction of AOP and AOP services.

I just posted some crappy AOP framework docs. The AOP framework generally works, but our AOP services are basically whiteboard right now. Whitepapers will be coming out once we get some AOP services working and the AOP framework more finalized.
