Spring light integration

Hello,

I'm currently working on a web project developped with Wicket and 
Cayenne. Everything worked fine but we are now planing to use Spring too.
I've seen the examples on the wiki, but i found it quite complex , since 
i don't want to go the DAO way.
Indeed, the only Spring/Cayenne interaction i need is for retrieving 
DataContext.
I wrote this in applicationContext.xml:

    <bean id="dataContext" class="org.apache.cayenne.access.DataContext" 
factory-method="getThreadDataContext" />
    <bean id="customPanel" class="eu.kwark.base.CustomPanel">
        <property name="context" ref="dataContext" />
    </bean>

But when i start my webapp, i get a "java.lang.IllegalStateException: 
Current thread has no bound DataContext"

Is there a way to go while keeping it simple and avoiding DAOs ?

Thanks for your help.

That is all you should need to do.

Thanks Malcolm.

I already set my web.xml this way :

    <filter>
        <filter-name>CayenneFilter</filter-name>
        <filter-class>
            org.apache.cayenne.conf.WebApplicationContextFilter
        </filter-class>
    </filter>
   <filter-mapping>
        <filter-name>CayenneFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

Is there something else to declare ?

Thanks for your help.

Hi Landry,

You will need to setup a DataContext servlet filter in your web application
to bind a DataContext to the request thread.
