According to the JNDI naming convention at http://docs.jboss.org/arquillian/reference/1.0.0.Alpha1/en-US/html/enrichment.html no-interface session beans cannot be tested directly. Their JNDI suffix is .../no-interface instead of .../local or .../remote.

To use no-interface session beans with JBossAS 6.0.0.M2 it is recommended to use jboss-ejb3-nointerface-impl-1.0.0-alpha-5.jar from http://repository.jboss.com/maven2/org/jboss/ejb3/nointerface/jboss-ejb3-nointerface-impl
