I have a read number of posts that indicates it is possible to have the following architecture listed below, however, putting @Name on the abstract class throws an IllegalArgumentException. If I remove @Name annotation from the abstract class, then my entityManager is null; it does not get injected. @Name("genericdao"); | public abstract MyBase <T, ID extends Serializable> implements mybaseInterface <T, ID> { | | @In | protected EntityManager entityManager; | } | | | @Stateless | @TransactionAttribute (TransactionAttributeType.REQUIRED) | @Name ("bean1") | public class Bean1 extends MyBase <Entity, ID> implements Bean1Interface { | | //do some dao acess here | } | | @Stateful | @Name ("bean2") | public class Bean2 implements Bean2Interface { | | //I have commented this in and out, does not make a difference. | @In private EntityManager entityManager; | | @In | Bean1 bean1 | | //use bean1 to do dao stuff, persist, remove, refresh, etc. | | } component.xml has the following: <persistence:managed-persistence-context name="entityManager" auto-create="true" | persistence-unit-jndi-name="java:/myEntityManagerFactory"/> persistence.xml has the following: .... | <persistence-unit name="myDatabase"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/DefaultDS</jta-data-source> | <jar-file>../my-common.jar</jar-file> | <jar-file>../my-party.jar</jar-file> | <jar-file>../my-security.jar</jar-file> | ...... | <properties> | ..... | <property name="jboss.entity.manager.factory.jndi.name" value="java:/myEntityManagerFactory"/> | .... | </persistence-unit> | .... I am trying to re-work my EJB style extended persistence context to use SMPC. Where I had @PersistenceContext to inject entityManager and @EJB to inject the beans. However swithching to @In to inject entityManager and my beans does not work. Please help, I have being reading old posts all knight long, and unable to get this to work. I am sure I am missing something obvious. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092277#...
