Urrrgs found the problem ... literal error in the interceptor definition :P

> <interceptor name="transactionInterceptor"
>
> class="org.gartenshop.interceptors.HibernateTransactionInterseptor"/>
> </interceptors>

> <action name="LoadArticleInformation"
> class="example.actions.LoadArticleInformation">
> <interceptor-ref name="transactionInterceptor"/>
> <!-- we don't define a result here because the action is

> </action>
> ...
> </package>

> When I try to load an object from my database this way, I always get

> *"load is not valid without active transaction".*
> In my opinion there is an active transaction bound to the Session

> I use DAOUtil.getSessionFactory().getCurrentSession() to get the
> Session object opened by the Interceptor.
