[jboss-user] [EJB 3.0] - broken column mapping exception on @OneToOne mapping
Hi all,
I got an exception on my entity mappings. The codes are as follows:table test (
| id
| name
| )
|
| table deleted_test (
| test_id
| person_id
| deleted_date
| )
|
| @Embeddable
| class PK {
| int test_id;
| int person_id;
| ...
| }
|
| @Entity
| @Table(name="deleted_test")
| class DeletedTest {
| PK pk;
| Test test;
| Person person;
| ...
| @EmbeddedId
| public PK getPk(){
| return pk;
| }
| ...setPk...
|
| @OneToOne(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
| @JoinColumn(name="Test_ID", nullable = false, insertable = false, updatable
= false)
| public Test getTest() {
| return test;
| }
| public void setTest(Test Test) {
| this.test = test;
| }
|
| @ManyToOne
| @JoinColumn(name="PERSON_ID", nullable=false, insertable = false, updatable
= false)
| public Person getPerson() {
| return person;
| }
|
| public void setPerson(Person person) {
| this.person = person;
| }
| ...
| }
When I run it on JBoss4.0.4GA and EJB3 RC8, I always got the following exceptions:
org.hibernate.MappingException: broken column mapping for: test.id of: DeletedTest

However,if I changed the test mapping to ManyToOne from OneToOne, no exceptions occured. I
want to know the OneToOne mapping here is wrong or not. I appreciate any directions. Thank
you in advance.
