[jboss-user] [EJB 3.0] - Re: My collection is not initializing; due to inheritance?

[snau2005]

I put here my example of 3 tables, i hope you asking of such example (in your case 2 tables)



  | @MappedSuperclass
  | public class IdTable implements Serializable {
  | 	@Id @GeneratedValue(strategy=GenerationType.TABLE)
  | 	public Long id;
  | 
  | }
  | 
  | @MappedSuperclass
  | public abstract class BasicPrimaryTable extends IdTable {
  | 			
  | 	@Version public Integer version;
  | }
  | 
  | @Entity
  | public class SomeTable extends BasicPrimaryTable {
  | 
  | }	 
  | 
  | 

if you dont want to extend some calss you need put like this:


  | @Embeddable
  | public class SomeClass {
  | 	@Column(nullable = false, length=255) public String name;
  | }
  | 
  | @Entity
  | public class SomeTable  {
  | @Embedded private SomeClass some;
  | }
  |
