Spring webflow can't access mvc beans

Question

I'm trying to use some @Service annotated classes (yes, using the mvc:annotation-driven) within the following Web flow :

manage-flow.xml

<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/webflow
    http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd" start-state="start" >



<view-state id="start" view="Userview.jsp" >

<on-render>

    <set name="flowScope.users"
        value="UserService.getUsers()">
    </set>
</on-render>
</view-state>
<bean-import resource="Manage-Beans.xml"/>
</flow>

Manage-Beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean class="com.dproductions.test.Service.SiteService" id="SiteService" />
<bean class="com.dproductions.test.Service.CustomerService" id="CustomerService" />
<bean class="com.dproductions.test.Service.UserService" id="UserService" />

 </beans>

When attempting to reach the flow I get the following stacktrace : http: //pastebin.com/QmCXe45Y

Which comes down to the Webflow not being able to access the specified package(s). But it doesn't give a 'ClassNotFoundException' , which is sort of puzzling to me.

Any suggestion is welcome.

Besides, my servlet-context is found here : Servlet-context

I've been fighting this for over a week now.

Edit

I want to be able to use my beans the way they are used at This Example , at the action states, the beans being picked up/managed directly by Spring MVC . Do the beans have to be declared (and serializable?) in the applicationcontext ? Using xml-notation ?

If I change the

<set>

towards an

<evaluate expression>

and have the beans defined in the file Manage-Beans.xml , it works.

But that way I have to define the same bean twice, as it is once picked up by the pkg-search annotation, and then in the web-flow it is again. I'd like to have the beans which are already made.

Spring web flow DOES re-create/instantiate the bean again. You can reference properties, autowire them with beans in the web-flow beans import file, but it's like a new context, unaware of existing beans. (Using events goes to both flow and normal-context files.)
