Hello All,
Ran into a strange problem (not really sure what is wrong) when I tried to
extend a working Entity Bean. The extended Entity Bean complains about a
collection in its parent class.
Here is the error message:
| org.hibernate.AnnotationException: Collection of elements must not have
mappedBy or association reference an unmapped entity: TrackedItem.userData
Here is TrackedItem:
@Entity
| @Inheritance(strategy=InheritanceType.JOINED)
| @DiscriminatorValue(value = "I")
| public class TrackedItem implements Serializable
| {
| ....
| @OneToMany(mappedBy="item", cascade = {CascadeType.ALL})
| @MapKey(name="key")
| private Map<String, UserDatum> userData;
| }
Here is UserDatum:
@Entity
| public class UserDatum implements Serializable {
| ...
| private String key;
| @ManyToOne
| private TrackedItem item;
| }
|
Here is Fail which extends TrackedItem:
@Entity
| @DiscriminatorValue(value = "S")
| public class Fail extends TrackedItem {
| ....
| }
Fail doesn't contain any collections or references to userData or UserDatum.
When I deploy TrackedItem and UserDatum everything deploys cleanly, works fine
and my unit tests pass. When deploy Fail, I get the error message above as the
reason the deployment failed.
Any help is appreciated!
Sincerely,
Stephen
