GlassFish has company!
TmaxSoft's JEUS 7 AppServer passed the
Java EE 6
compatibility at the end of December and is
JEUS 7 is currently available only as a Technology Preview, with the final release
planned for the end of 2010.
I expect a fairly rapid adoption of JavaEE 6.
JBoss and Caucho have indicated their intent to release Web Profile
App Servers "soon".
Geronimo 3 will implement the full profile
by the end of 2010
and so will the final JBoss 6.
And, of course, the modular GlassFish v3
already supports Web and full Profile.
