OptimisticLockException confusion.
Hi,
I am having trouble catching the OptimisticLockException that is being
thrown when I have concurrent users trying to update the same entity.
Basically I want to be able to do is to send the one user to another page in
my app when this exception is thrown, but for some reason my attempts to
catch it are not working. I apologize if its something minor, im kinda of
new to java ee. I thought by catching the openjpa OptimisticLockException
and throwing the javax.persistence.OptimisticLockException I could achieve
the desired behaviour in the web app. But it seems I cannot catch the
openjpa Exception.
Thanks for any help.
Entity with @version annotation
@Entity
@Table(name="mt_interns")
@DiscriminatorValue("CI")
public class ChoiceIntern extends Intern implements Serializable {
private static final long serialVersionUID = 1L;
@Column(name="has_position")
private boolean hasPosition;
@OneToMany(cascade = ALL,fetch=EAGER)
@JoinTable(name = "MT_INTERN_CHOICES", joinColumns = { @JoinColumn(name =
"INTERN_ID") }, inverseJoinColumns = { @JoinColumn(name = "CHOICE_ID") })
private List<Choice> choices;
@OneToMany(cascade = ALL,fetch=EAGER)
@JoinTable(name = "MT_INTERN_SKILLS", joinColumns = { @JoinColumn(name =
"INTERN_ID") }, inverseJoinColumns = { @JoinColumn(name = "SKILL_ID") })
private List<InternSkill> skills;
......
Stateless Session Bean
...
Match match = new Match(manager, intern, request, percentage);
intern.setHasPosition(true);
numberOfInterns = numberOfInterns + 1;
request.setNumberOfInternsSelected(numberOfInterns);
emMatchMaker.merge(intern);
emMatchMaker.persist(match);
emMatchMaker.merge(request);
insertedInterns.add(intern);
} catch (OptimisticException oe) {
System.out.println("I caught the inner locking exception!");
throw new javax.persistence.OptimisticLockException(oe);
}
...

Re: OptimisticLockException confusion.
Posted by Rajeev Jha <jh...@gmail.com>.
Hi
If you trying commit directly after persist w/o doing an explicit
flush then OptimisticLocking Exception maybe nested inside
RollBackException. What is the top most error on stack? You can catch
javax.persistence.PersistenceException and try to do this kind of
error translation
public static void getThrowable(javax.persistence.PersistenceException
perex, int code) {
boolean updateError = false ;
boolean deleteError = false ;
KentException kentex = null ;
Throwable th = null ;
if( perex instanceof org.apache.openjpa.persistence.RollbackException) {
th = perex.getCause();
if(th instanceof OptimisticLockException) {
updateError = true ;
}
}
if(perex instanceof OptimisticLockException ){
updateError = true ;
th = perex ;
}
if(perex instanceof org.apache.openjpa.persistence.EntityNotFoundException) {
deleteError = true ;
th = perex ;
}
Thanks
- rajeev.

Re: OptimisticLockException confusion.
Posted by Craig L Russell <Cr...@Sun.COM>.
Hi,
Usually, inserts/updates/deletes are grouped for efficiency when the
transaction is ended.
But for your case, you want to force the update to the database while
you are still in control.
Try EntityManager.flush() and catch the exceptions.
