Ok bfo81 lets see:
My Entity Class:
package org.jboss.seam.example.client;
|
| import javax.persistence.Entity;
|
| import org.hibernate.validator.Length;
| import org.hibernate.validator.NotNull;
|
| @Entity
| public class ClientPerson extends Client {
|
| private static final long serialVersionUID = 7829975195914473729L;
| private String firstname;
| private String lastname;
|
| @NotNull
| @Length(min=2, max=5)
| public String getFirstname() {
| return firstname;
| }
|
| public void setFirstname(String firstname) {
| this.firstname = firstname;
| }
|
| @NotNull
| public String getLastname() {
| return lastname;
| }
|
| public void setLastname(String lastname) {
| this.lastname = lastname;
| }
|
|
|
|
|
| }
|
My Edit Action:
package org.jboss.seam.example.client;
|
| import javax.ejb.Remove;
| import javax.ejb.Stateful;
| import javax.ejb.Stateless;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;

|
| @Stateful
| @Name("clientPersonAction")
| public class ClientPersonEditAction implements ClientPersonEdit{
|
| @PersistenceContext
| private EntityManager em;
|
| @RequestParameter()
| private Long clientPersonId;
|
| @In(required=false)
| @Out(scope=ScopeType.PAGE,required=false)
| private ClientPerson newClientPerson;
|
| @Begin(join=true)
| @Factory("newClientPerson")
| public void createNewClientPerson()
| {
| if(clientPersonId != null)
| {
| ClientPersonDAO clientPersonDAO = new
ClientPersonDAO(em);
| newClientPerson =
clientPersonDAO.getClientPersonById(clientPersonId);
| System.out.println("createNewClientPerson:" +
newClientPerson.getId());
| }
| else
| {
| newClientPerson = new ClientPerson();
| }
| }
|
| @End
| public String saveClientPerson() {
| ClientPersonDAO clientPersonDAO = new ClientPersonDAO(em);
| System.out.println("newClientPerson.getId():" +
newClientPerson.getId());
| clientPersonDAO.merge(newClientPerson);
| return "home";
| }
|
| @Destroy @Remove
| public void detroy()
| {
| }
|
| @End
| public String removeClientPerson() {
| ClientPersonDAO clientPersonDAO = new ClientPersonDAO(em);
| clientPersonDAO.remove(newClientPerson);
| return "home";
| }
|
| }
|
My DAO Class for the Entity:
package org.jboss.seam.example.client;
|
| import java.util.List;
|
| import javax.persistence.EntityManager;
| import javax.persistence.Query;
|
| public class ClientPersonDAO {
|
| private EntityManager entityManager;
|
| public ClientPersonDAO()
| {
|
| }
|
| public ClientPersonDAO(EntityManager entityManager)
| {
| this.entityManager = entityManager;
| }
|
| public EntityManager getEntityManager() {
| return entityManager;
| }
|
| public void setEntityManager(EntityManager entityManager) {
| this.entityManager = entityManager;
| }
|
| public void persist(Object obj)
| {
| getEntityManager().persist(obj);
| }
|
| public void merge(Object obj)
| {
| getEntityManager().merge(obj);
| }
|
| public List<ClientPerson> getAllClientPerson() {
| return getEntityManager().createQuery("select c from
ClientPerson c").getResultList();
| }
|
| public ClientPerson getClientPersonById(long id) {
| Query q = getEntityManager().createQuery("select c from
ClientPerson c where c.id = :id");
| q.setParameter("id", id);
| return (ClientPerson) q.getSingleResult();
| }
|
| public void remove(ClientPerson clientPerson) {
| getEntityManager().remove(clientPerson);
| }
|
| }
