Hi

I use JPA with Hibernate3.5 on JBOSS5.1.
I developped a new generator for internal purpose. In JPA there is no way to define new generator so I used a implementation of IdentifierGenerator.

I configure the generator like this on a entity :
@Id
@GeneratedValue(generator = "NUOGenerator")
@GenericGenerator(name = "NUOGenerator", strategy = "jpa.NUOGenerator")
@Column(unique = true, nullable = false)
public long getId() {
return this.id;
}

The problem I have is to get a new transaction from my :
public Serializable generate(SessionImplementor sessionImplementor,
Object object) throws HibernateException;

I can not I have an error that said I cannot attach JTA transaction to the current context.
I use persistence.xml to configure my application :
