And I've got a message from Marek Schmidt that the seam-booking
was
not tested with Glassfish 3.0 yet. So expect results about this one
next week.
...and here it is!
https://issues.jboss.org/browse/SEAM-41
Summary: It doesn't work on glassfish 3.0.1, there appears to be an
conflict between weld 1.0.1-SP3 in glassfish 3.0.1 and
Seam Servlet CR1, as both contain HttpSession producers.
