Via Greg, some interesting adoption data on Spring vs. EJB. Of course Rod Johnson (Springsource CEO and Spring inventor) is anything but unbiased on this. I haven’t seen any corroboration of his data but it is consistent with the zeitgeist. Greg’s take on what it means for standards is interesting too. I think what he says is especially true for standards that target portability (like J2EE and SCA) versus those that target interoperability. Standardization (including de-facto) is a must for a protocol but a “nice to have” for a development framework. But then again, now that even IT management has BarCamps, maybe even boring IT management interoperability protocols could emerge from the bottom up.
