[jboss-user] [JBoss Seam] - EntityHome.persist - Getting the generated id?

[dustismo]

Hi,

I have an entity home class and I need to get the generated id (database generated) of the persisted object after calling persist (I would have thought this would be automatic?)..  It always comes back as 0.

Here is my entityHome class:


  | @Name("userHome")
  | public class UserHome extends EntityHome<User> {	
  | 	@In
  | 	private EntityManager entityManager;
  | 	
  | 	public void setUserId(Integer id) {
  | 		setId(id);
  | 	}
  | 
  | 	public Integer getUserId() {
  | 		return (Integer) getId();
  | 	}
  | 	
  | 	@Override
  | 	protected User createInstance() {
  | 		User u = new User();
  | 		return u;
  | 	}
  | 	
  | 	@Override
  | 	public String persist() {
  | 		
  | 		String retval = super.persist();
  | 		User u = this.getInstance();
  | 		System.out.println("Persisted user: " + u.getName() + " id: " +
  | 				u.getId() + " this.id: " + this.getId());
  | 		return retval;
  | 	}
  | }

And the entity:


  | @Entity
  | @Name("user")
  | @Scope(SESSION)
  | @Table(name = "User")
  | public class User implements java.io.Serializable {
  | 
  | 	// Fields    
  | 	private int id;
  | 
  | 	private String name;
  | 
  | 	private String password;
  | 
  | 	// Constructors
  | 
  | 	/** default constructor */
  | 	public User() {
  | 	}
  | 
  | 	// Property accessors
  | 	@Id
  | 	@Column(name = "id", unique = true, nullable = false)
  | 	@NotNull
  | 	public int getId() {
  | 		return this.id;
  | 	}
  | 
  | 	public void setId(int id) {
  | 		this.id = id;
  | 	}
  | 
  | 	@Column(name = "name", nullable = false, length = 64)
  | 	@NotNull
  | 	@Length(min = 3, max = 64)
  | 	public String getName() {
  | 		return this.name;
  | 	}
  | 
  | 	public void setName(String name) {
  | 		this.name = name;
  | 	}
  | 
  | 	@Column(name = "password", nullable = false, length = 16)
  | 	@NotNull
  | 	@Length(min = 4, max = 16)
  | 	public String getPassword() {
  | 		return this.password;
  | 	}
  | 
  | 	public void setPassword(String password) {
  | 		this.password = password;
  | 	}
  | }

Many thanks,
Dustin
