We've been through this discussion many times before. See for example
my recent discussion with Thomas Diesler in the webservices forum.

The short answer to your question (on the errors above), 
is that you shouldn't be writing the deployers
in the ejb3 plugin project(s). 

Instead the deployers should be in JBossAS and they should delegate to
a stable spi within EJB3

In fact, that spi (the ejb3 integration api) should be in the jboss-integration project
where you can't change it on a whim. :-)

The deployers themselves should be doing little more than
manipulating metadata which then gets registered as a "service" in the Microcontainer.
Those services should then talk to an "EJB3 Service" from the deploy directory.

Again see recent discussion in Tomcat forum about how the Tomcat
deployers were wrong.
