Hello!
Just started using EJB 3.0 so bare with me please..
The question is regarding an entity with an auto generated ID
public class Appointment implements Serializable {
...
private int appid;
...
@Id @GeneratedValue
@Column(name="APP_ID")
public int getAppId( ) { return appid; }
public void setAppId(int pk) { appid = pk; }
...
}
When I take an instance of this POJO entity and persist it
entitymanager.persist(appointment);
I would like to know what appId it was given since I need this value for the next step in my process.
I cannot use entitymanager.find(..) since I don't know the PK and performing a query on all the other columns cant be done since they are not unique.
There must be a better way.. Does anyone know?
Thanks a lot!
Scott

Hi,
Suppose,
1 .Module in the entity-is having the getter/setter method
2. After Module entity is persisted, then you can get the Primary key value
entitymanager.persist(module);
By debug mode,check primary key value present/ or not in the module entity attributes after calling the above method.
I think, this will solve your problem.
