Eduard,
I am still getting a ClassNotFound error on OpenSessionInViewFilter at startup.
I have found two jar files that contain the class, spring.jar and
spring-hibernate3.jar, and it fails with both of them.
I have configured applicationContext.xml like this:
<bean name="openSessionInViewInterceptor"
class="org.springframework.orm.hibernate3.support.OpenSessionInViewFilter">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
<property name="flushModeName">
<value>FLUSH_AUTO</value>
</property>
</bean>
is there anything else I have neglected to do? Some other configuration,
perhaps?
--Dennis

Hm,
interesting. I checked against my configurations. I have in my WEB-INF/lib
spring.jar, all necessary hibernate archives and the configuration of filters
is done as described in the link I already posted.
Best
