Sitting now in an interesting talk about new features of Glassfish v3 session. The speaker (Ludovic Champenois) mentioned that since today (18.03.2009) Glassfish v3 is able to swap the OSGI implementation and run e.g. on Equinox. So far it seems to be the first server, which is able to do this.
NEW: Online Workhop Effective WebApps without Frameworks is also coming to: MUC Airport.
