Hi everybody,
I finally decided to switch to Tapestry/Spring/Hibernate and the first
step for me was to try to get Howard's tapestry-spring jar to work.
Besides an error message I don't understand (please see below, any
tips are very welcome!) I've also found a reference to a
"OpenSessionInViewFilter" in the Tapestry wiki
->
http://wiki.apache.org/jakarta-tapestry/FrequentlyAskedQuestions/SpringHibernate
My first question is: Do I need that even if I use the tapestry-spring jar?! :)
My second question is: At the moment my servlet is managed by
org.apache.tapestry.ApplicationServlet (defined in web.xml).
Do I have to change that to a Spring class?
The last question is related to the error message I mentioned above:

The (as to my opinion) relevant applicationContext.xml part looks like:
<!-- SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop
key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.generate_statistics">false</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
</props>
</property>
</bean>
Whats going wrong here? Please request if you need more information concerning
the rest of my setup.
Thanks in advance,
Andreas
