I have a problem with the "long-lived" transaction in my ejb3 project, which
built in JBossAS4.0.4RC1 with install-component "all".
I found the file "persistence.properties" under "ejb3.deployer\META-INF" is
configurated by default like this:
hibernate.transaction.flush_before_completion=true
I think it supports not the "long-lived" transaction, because if i change this
"flush_before_completion" value to "false", it runs without problem with
"PersistenceContextType.EXTENDED"
(@PersistenceContext(unitName="...",type=PersistenceContextType.EXTENDED))
My problem is, in my "old" ejb3 project in JBossAS4.0.3SP1, i try to load the
"lazy fetch" Object in EntityBeans with the function like this:
| @ManyToOne(cascade={}, fetch=FetchType.LAZY)
| @JoinColumn(name="mandant_id", unique=false, nullable=true,
insertable=true, updatable=true)
| public InfondsMandant getMandant() {
| Hibernate.initialize(this.mandant);
| return this.mandant;
| }
|
and by default i dont need to configurate the file "persistence.properites" to
support the "long-lived" transaction.
But now if i want to load the "lazy fetch" Object with the funktion
"Hibernate.initialize()" under the configuration
"flush_before_completion=false("long-lived" support)", it throws the exception
"org.hibernate.LazyInitializationException: could not initialize proxy - no
Session".
And if i set the value of "flush_before_completion" back to "true", the
function "Hibernate.initialize(lazy)" runs but fine.
So now i cannt use the "long-lived transaction" and Hibernate.initialize(lazy)
together.
Someone knows that, how should i do, so that JBoss supports them both?
thanks alot for your helpers!
