What Java EE 6 preview technologies are available?
The following table lists Java EE 6 preview technologies that are available for use with GlassFish v3 Prelude:
EJB Container 3.1
JSF 2.0 Preliminary
Weld is only in the latest GF V3 build 70, it is neither in Prelude nor in Preview.
Technically, GlassFish V3 (and Prelude) are previews of an EE6 app server, neither of them have passed the full EE6 testsuite.
