Loosing PK on query

[hilwi]

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.

I forgot to post my client-code to retrieve the addresses:

 protected void GetAddresses() {
 try {
 Context context = ClientTools.getInitialContext();
 Object ref = context.lookup("AddressesBean/remote");
 Addresses addresses = (Addresses)PortableRemoteObject.narrow(ref,Addresses.class);
 setLstAddresses(addresses.getAllAddresses());

 for (int i=0; i<lstAddresses.size(); i++) {
 System.out.println(((Address)lstAddresses.get(i)).getName1()+String.valueOf(((Address)lstAddresses.get(i)).getId()));
 }

 } catch (Exception e) {
 e.printStackTrace();
 }
 }

As I manetioned in my previous post, the function getName1() returns the currect names of the addresses but the getId() always returns 0.

try:

...
@MappedSuperclass
public class JbsObject implements Serializable {

private long id;

...

This works!! Thank you!
