This causes a problem, as Seam uses a ServletListener to boot itself, and can try look up EJB3s using JNDI (as described http://docs.jboss.org/ejb3/app-server/tutorial/jndibinding/jndi.html ).

This is reproduced by running

cd jbossas/testsuite
./build.sh _jars-seam
cp output/lib/jboss-seam-dvd* ../build/output/jboss-5.0.0.Beta4/server/default/deploy
cd ../build/output/jboss-5.0.0.Beta4
./bin/run.sh

You should get a NamingException from Seam, as it fails to look up the EJB3.

Note, the deployment order is different if you deploy to the already running app server.
