Hello,
Of course you can persist relations in one method.
| public void persistParent(Parent p)
| {
| ParentEntityBean pBean = new ParentEntityBean(p);
| em.persist(pBean);
|
| List<Child> children = p.getChildren();
| Child firstChild = children.get(0);
| ChildEntityBean cBean = new ChildEntityBean(firstChild);
| em.persist(cBean);
|
| ParentChildRelationEntityBean pcRelBean = new
ParentChildRelationEntityBean(pBean,cBean);
| em.persist(pcRelBean);
|
| }
|
I think you have problem there :
|
| @Entity
| @Table(name = "kennel_dogs")
| public class KennelDogsEntity implements Serializable
| {
| private KennelEntity kennelD;
| private DogsEntity dogID;
|
| public KennelDogsEntity() {}
|
| public KennelDogsEntity(KennelEntity kennelID, DogsEntity dogID)
| {
| this.kennelID = kennelID;
| this.dogID= dogID;
| }
|
| @Id
| @ManyToOne(optional=false)
| // @JoinColumn(name="dogID")
| @JoinColumn(name="dogID", insertable=false, updatable=false)
| public DogsEntity getDogID()
| {
| return dogID;
| }
|
| @Id
| @ManyToOne(optional=false)
| // @JoinColumn(name="kennelID")
| @JoinColumn(name="kennelID", insertable=false, updatable=false)
| public KennelEntity getKennelID()
| {
| return kennelID;
| }
|
| ... setters ...
| }
|
|
I hope it would be useful.
