GlassFish Day is part of CommunityOne on May 7th. The website is now showing more details and specifically the agenda.
Tim O’Reilly will be the keynote speaker.
Note also the list of partners. All will be present showing demos.
Update 1: if you are already registered for javaOne, you are offered several (not so user-friendly choices) to provide your registration ID and add CommunityOne to your JavaOne schedule (the same badge will work for both events).
Update 2: if you are not going to JavaOne, CommunityOne is your chance to get into JavaOne’s Day 1 for the general session, the welcome reception, the exhibition and 2 sessions or BOFs of your choice. You only need to be an SDN member (which is free).
