Sure, you can. My experience as code (a simple example): ACTION: | @Name("userAction") | @Scope(ScopeType.CONVERSATION) | public class UserAction { | | @In(required = false) | @Out(required = false) | private User user; | | @In(create = true) | protected UserService userService; | | @End | public String create() { | try { | | userService.create(user); | addCreatedMessage(); | return Outcome.SUCCESS; | } catch (EntryDuplicatedException e) { | addDuplicatedMessage(); | return null; | } | } | } | SERVICE: | | @Stateful | @Name("userService") | @Scope(CONVERSATION) | public class UserServiceBean implements UserService { | | | @In(value="#{entityManager}") | private EntityManager em; | | | public void create(User entity) throws EntryDuplicatedException { | try { | em.persist(entity); | em.flush(); | } catch (EntityExistsException e) { | throw new EntryDuplicatedException(); | } | } | | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4086078#4086078 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4086078 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
