Open Session in View Filter Spring Hibernate Struts

[sebajb]

I am using OpensessionInViewFilter for hibernate 3 "org.springframework.orm.hibernate3.support.OpenSe ssionInViewFilter" and I keep getting the lazy initialization error.

Here is the filter configuration in web.xml:
<filter>
<filter-name>openSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSes sionInViewFilter
</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>openSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


Here is the hibernate properties in the sessionFactory configuration:
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SybaseDialect
</prop>
<prop key="show_sql">true</prop>
<prop key="hibernate.cache.use_second_level_cache">
false
</prop>
</props>
</property>

I am using declared transaction management and am unsure if this should matter or not.

I am also using struts and accessing the spring bean through struts. Note that I am not using spring through the struts plugin, but rather through the org.springframework.web.struts.DelegatingActionPro xy.

I would love some help. It sounds like this should work.
Is there a standard way to configure

Hi,

I'm new to spring but i got my openSessionInViewFilter working.

What i did is adding the following to my web.xml:
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSes sionInViewFilter
</filter-class>

</filter>

<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>

This is a part from my applicationContext.xml file:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSes sionFactoryBean">
<property name="mappingResources">
<list>
<value>rsswebclient/domain/Item.hbm.xml</value>
<value>rsswebclient/domain/Channel.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
<property name="dataSource">
<ref bean="dataSource" />
</property>
</bean>

There must by a sessionFactory bean present in the applicationContext.xml or you will get "No bean named 'sessionFactory'" error.

Hope it helps.

Kind Regards,

Josip

I have done exactly as you said and I believe the configuration is correct. My problem might in the fact that I am using hibernate through annotations instead of the usual .hbm.xml files.

Is there anything special happening with annotations and spring. Do I need to use the @Transaction in the Pojo?

Anyhelp would be appreciated.

I'm not using annotations. Maybe it has something to do with it. Could you post the logging.
