I'm seeing this problem in both the installer ejb3 profile, and the current 4.0 branch build of the jboss-4.0.4.GA-ejb3 dist. Is there a configuration of the ejb3 container that has to be updated for the use of javassist? 00:08:22,272 INFO [JmxKernelAbstraction] jboss.jca:name=bookingDatasource ,service=ManagedConnectionFactory 00:08:22,319 INFO [Version] Hibernate EntityManager 3.2.0.CR1 00:08:22,334 INFO [Version] Hibernate Annotations 3.2.0.CR1 00:08:22,350 INFO [Environment] Hibernate 3.2 cr2 00:08:22,365 INFO [Environment] hibernate.properties not found 00:08:22,365 INFO [Environment] Bytecode provider name : cglib 00:08:22,381 WARN [ServiceController] Problem starting service persistence.units:ear=jboss-seam-booking.ear,jar=jboss-seam-booking.jar, unitName=bookingDatabase java.lang.RuntimeException: java.lang.NoClassDefFoundError: net/sf/cglib/transform/ClassFilter at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWrappe r.java:105) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupp ort.java:289) at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBean Support.java:245) at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) I'm seeing similar problems running the ejb3 tests: [EMAIL PROTECTED] ejb3]$ ant -buildfile build-test.xml no-start-jboss-ejb-tests 00:35:08,865 INFO [JmxKernelAbstraction] jboss.jca:name=DefaultDS,service =ManagedConnectionFactory 00:35:08,897 INFO [Version] Hibernate EntityManager 3.2.0.CR1 00:35:08,928 INFO [Version] Hibernate Annotations 3.2.0.CR1 00:35:08,944 INFO [Environment] Hibernate 3.2 cr2 00:35:08,959 INFO [Environment] hibernate.properties not found 00:35:08,959 INFO [Environment] Bytecode provider name : cglib 00:35:52,178 WARN [ServiceController] Problem starting service persistence.units:jar=salesforce-7123.jar,unitName=tempdb java.lang.RuntimeException: java.lang.NoClassDefFoundError: net/sf/cglib/transform/ClassFilter at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWra pper.java:105)
