An exploded EAR deploys and runs fine with JBossAS 4.2.2. Adapting some DTD declarations and package names I tried the deployment with for 5.0.0CR1 and failed. The stacktrace is below. The problem: - KundenverwaltungBean is a SLSB and references the SLSB BestellverwaltungBean via its interface Bestellverwaltung - The reference is declared with @PersistenceContext and @IgnoreDependency because BestellverwaltungBean also has a reference back to KundenverwaltungBean via its interface Kundenverwaltung - BestellverwaltungBean has a field "em" of type EntityManager being annotated with @PersistenceContext(name="hskaPersistence") - hskaPersistence is the name of <persistence-unit> inside META-INF/persistence.xml Here is the stacktrace. Any hint is appreciated! Is this a bug in the hot deployment scanner? 2008-07-04 06:00:55,388 INFO [org.apache.coyote.ajp.AjpAprProtocol] (main) Starting Coyote AJP/1.3 on ajp-localhost%2F127.0.0.1-8009 | 2008-07-04
