Well the only workaround I have founded is to put all the build files in ONE director (eg. target/classes) and not target/classes for EJB and target/test-classes for test configurations (embedded-ejb,.class, configurations) finally I have 2 questions: Why BookingTest works and notBookingUnitTest ? Is there a way to say to the PersistenceManager to look at in another directory (eg. target/classes)? Thanks in advance Regards, Alexandre View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3991741#...
