    EntityManager is an interface, and JAXB can't handle interfaces

    Sam W Expert

      Hello,

       

      With Jboss 6.0.0.Final, I tried to deploy a war file to the AS. The application is use Webservices to expose the functionalities of EJB3 entities.

       

      Here is the error with its exceptions:

       

      *** DEPLOYMENTS IN ERROR: Name -> Error

       

       

      vfs:///C:/jboss-6.0.0.Final/server/default/deploy/houseware.war -> org.jboss.deployers.spi.DeploymentException: Error during deploy: vfs:///C:/jboss-6.0.0.Final/server/default/deploy/houseware.war

       

       

      DEPLOYMENTS IN ERROR:

        Deployment "vfs:///C:/jboss-6.0.0.Final/server/default/deploy/houseware.war" is in error due to the following reason(s): com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions

      javax.persistence.EntityManager is an interface, and JAXB can't handle interfaces.

              this problem is related to the following location:

                      at javax.persistence.EntityManager

                      at private javax.persistence.EntityManager au.com.houseware.ws.jaxws_asm.GetEntityManagerResponse._return

                      at au.com.houseware.ws.jaxws_asm.GetEntityManagerResponse

      javax.persistence.EntityManager does not have a no-arg default constructor.

              this problem is related to the following location:

                      at javax.persistence.EntityManager

                      at private javax.persistence.EntityManager au.com.houseware.ws.jaxws_asm.GetEntityManagerResponse._return

                      at au.com.houseware.ws.jaxws_asm.GetEntityManagerResponse

       

       

      Here are a list of java classes that I have created::

      RoleJpaController.java,  RoleWS.java

       

      RoleJpaController.java:


       

      @Stateless

      public class RoleJpaController  {

       

       

          private EntityManagerFactory emf = null;

       

       

          public RoleJpaController() {

              emf = Persistence.createEntityManagerFactory("housewarePU");

          }

       

       

          public EntityManager getEntityManager() {

              return emf.createEntityManager();

          }

      ....

       

       

      RoleWS.java:


      @WebService()

      @Stateless()

      public class rolews {

          @EJB

          private RoleJpaController ejbRef;

       

       

          @WebMethod(operationName = "getEntityManager")

          public EntityManager getEntityManager() {

              return ejbRef.getEntityManager();

          }

       

       

          @WebMethod(operationName = "create")

          public void create(@WebParam(name = "role")

          Role role) throws PreexistingEntityException, Exception {

              ejbRef.create(role);

          }

      ....

       

       

      Have I done anything wrong with the way how I use these java classes?

       

      Very appreciate for any suggestion and help.

          Mark Paluch Master

          Hi Sam,

          you should not expose the EntityManager as Web-Method since it's bad design. A better approach is exposing a method, which returns the data you need.

          The root-problem is javax.persistence.EntityManager does not have a no-arg default constructor and since EntityManager is not Serializable that would be the next Problem.

           

          Best regards,

          Mark

            Hi Mark,

             

            Thank you for the suggestion.

            I made RoleJpaController implements Serializable interface, but it still gave me the same exception. Yes I guess it is not so obvious like that.

            How would you make EntityManager Serializable?

             

            Thanks

              Nicklas Karlsson Master

              Like Mark said, I think the root problem is that JAXB needs to instantiate stuff. And for that, it needs to be a concrete class with a no-args constructor.

                Sam W Expert

                Opps... pardon me, I never though EntityManager is an interface .

                 

                Thank you very much for the hints.

                 

                I will see how it goes after I implemented a concrete class of EntityManager..

                 

                Thanks

                    Sam W Expert

                    I still don't know how to implement this idea.

                     

                    Here is the RoleJpaController class using the EntityManager:

                     

                    @Stateless

                    public class RoleJpaController {

                       

                        private EntityManagerFactory emf;

                     

                     

                        public RoleJpaController() {

                            emf = Persistence.createEntityManagerFactory("housewarePU");

                        }

                     

                     

                        public EntityManager getEntityManager() {

                            return emf.createEntityManager();

                        }

                     

                     

                        public void create(Role role) throws PreexistingEntityException, Exception {

                            if (role.getUserList() == null) {

                                role.setUserList(new ArrayList<User>());

                            }

                            EntityManager em = null;

                            try {

                                em = getEntityManager();

                                em.getTransaction().begin();

                                List<User> attachedUserList = new ArrayList<User>();

                                    userListUserToAttach = em.getReference(userListUserToAttach.getClass(), userListUserToAttach.getUserId());

                                    attachedUserList.add(userListUserToAttach);

                                }

                                role.setUserList(attachedUserList);

                                em.persist(role);

                                for (User userListUser : role.getUserList()) {

                                    Role oldRoleOfUserListUser = userListUser.getRole();

                                    userListUser.setRole(role);

                                    userListUser = em.merge(userListUser);

                                    if (oldRoleOfUserListUser != null) {

                                        oldRoleOfUserListUser.getUserList().remove(userListUser);

                                        oldRoleOfUserListUser = em.merge(oldRoleOfUserListUser);

                                    }

                                }

                                em.getTransaction().commit();

                            } catch (Exception ex) {

                      Read the first reply from Mark again!

                       

                      > you should not expose the EntityManager as Web-Method since it's bad design.

                      > A better approach is exposing a method, which returns the data you need.

                       

                      Do not expose the getEntityManager method (I can't see why you wish to do that)

                       

                      Keep the create method exposed:

                       

                          @WebMethod(operationName = "create")

                          public void create(@WebParam(name = "role")

                       

                      Isn't that what you want to expose?

                        Hi Anders,

                         

                        Thank you for your response.

                        I actually have removed the @WebMethod on the getEntityManager method, but the exception still happened.

                          Hmm.. Is it still saying "javax.persistence.EntityManager is an interface, and JAXB can't handle interfaces." or is someother class that it complains about now?

                           

                          A quick test would be to remove the method completely from rolews

                           

                          <!--

                          public EntityManager getEntityManager() {

                                  return ejbRef.getEntityManager();

                              }

                          -->

                           

                          Can't see why you need it anyway!

                            Thank you for your suggesiton, you are right, it is the problem with the getEntityManager(). I have to removed it.

                            Now another error shown up:

                                  Tip of the day: If you're not sure what you need, take out *all* libs, only package stuff that gives ClassNotFoundException at runtime...

                                    Thank you for the suggestion. I have tried to remove antr and hibernate3, but it caused tons of errors.

                                    As I searched in google for a while, and found the following suggesiton:
