Hello!
I'm having a strange problem with my EJBs. I have created a base-class for my
entity-ejbs that contains the primary-key-field and some other fields:
| ...
| @MappedSuperclass
| public class JbsObject {
|
| private long id;
|
| @Id
| public long getId() {
| return id;
| }
|
| public void setId(long id) {
| this.id = id;
| }
|
| ...
| }
|
Now I have an entity-ejb named "Address" that defines some more fields like
"name", ...
| @Entity
| public class Address extends JbsObject implements Serializable {
| ...
| }
|
The tables are created correctly and I can add new entities without any
problems.
Now I want to fetch a list of addresses with a simple query in my stateless
session-bean "AddressesBean":
| @Stateless
| public class AddressesBean implements Addresses {
|
| @PersistenceContext(unitName="testapp")
| private EntityManager manager;
|
| public List getAllAddresses() {
| Query q = manager.createQuery("from Address");
| return q.getResultList();
| }
| ...
| }
|
When I invoke this method from my client-application I can retrieve all
addresses with their data except their id. The id of every instance is 0. I
have printed out the ids within the getAllAddresses-function - all is ok there.
Only on the client I have no ids.
What am I doing wrong?
I'm using JBoss 4.04GA with Linux.
