Thanks for your reply.
My entity does have the relevent field annotated as unique
| @Column(nullable=false, unique=true)
| public String getUsername() {
| return username;
| }
|
| public void setUsername(String username) {
| this.username = username;
| }
|
and I have a em.flush() in my session bean. As I mentioned before, the
Exception is caught by my session bean.
org.hibernate.exception.ConstraintViolationException
but then I get:
16:37:20,640 ERROR [AssertionFailure] an assertion failure occured (this may
indicate a bug in Hibernate, but is more likely due to unsafe use of the
session)
| org.hibernate.AssertionFailure: null id in
com.sega.kongo.entity.user.KongoUser entry (don't flush the Session after an
exception occurs)
This makes some sense to me...because the creation of the User failed, the 'id'
will indeed be null. I tried to rollback the transaction (in the 'catch' block
of my session bean
em.getTransaction().rollback();
but that failed miserably with the following exception message: Illegal to call
this method from injected, managed EntityManager
Just to make sure that this isn't a potential bug in JBoss, with which version
of JBoss have you successfully applied this strategy? I'm using jboss-4.0.3SP1.
Thanks as always,
Jason
