Hi,

I have a problem and can't resolve it.
My application configuration: web tier(Spring MVC) -> business tier(Session EJB + Hibernate) -> database.
Everything is deployed on JBoss. I deployed hibernate mapping classes nad configuration files using 'har' file.
I try to use optimistic locking with version checking.
My hibernate mapping file:


Code:
<class name="persistent.Produkt" optimistic-lock="version" table="produkt" schema="dbo" catalog="j2ee">
        <id name="id" type="integer">
            <column name="id" />
            <generator class="identity" />
        </id>
        <version
         column="version"
         name="version"
         type="integer"
      />
        <property name="opis" type="string">
            <column name="opis" length="200" not-null="true" />
        </property>
        <property name="cena" type="big_decimal">
            <column name="cena" precision="10" not-null="true" />
        </property>
        <set name="szczZams" inverse="true">
            <key>
                <column name="id_prod" not-null="true" />
            </key>
            <one-to-many class="persistent.SzczZam" />
        </set>
    </class>


Method in my HibernateDAO, which I use to attach detached object:
Code:
public void attachDirty(Produkt instance) throws VersionException {
        log.debug("attaching dirty Produkt instance");
        try {
            sessionFactory.getCurrentSession().saveOrUpdate(instance);
            log.debug("attach successful");
        }
        catch (org.hibernate.StaleObjectStateException soe) {
           throw new VersionException("Element was changed. ",soe);
        }

    }


I try to update Produkt instance using Session EJB method, which uses HibernateDAO attachDirty(Produkt instance) method. When, in another session, someone else changed the product, I should be able to catch StaleObjectStateException and do some action. But I can't do anything, because JBoss take control of exception: rollback transaction, remove Session EJB instance and throw exceptions to the web tier:

I need your help. I need to control the version checking process, to show application users some information.
