I am checking feasibility of EJB3 based web services.
So, I created a tiny session bean and successfully built EJB module.
However when I am trying to deploy it to JBOSS 4.2.1 I am getting this:

15:59:03,811 INFO [Server] JBoss (MX MicroKernel) [4.2.1.GA (build: SVNTag=JBoss_4_2_1_GA date=200707131605)] Started in 18s:749ms

Installation page says that JBoss AS 4.2.x versions include support for EJB3, by default.
Can someone tells me what I am missing and how to fix the problem.
Thanks a lot.
