Spring Portlet MVC and bean scopes

[em@garp.se]

Background:
Developing a spring portlet using Spring Portlet MVC to be used in liferay.
Using Liferay version 5.1.1.
Spring version 2.5.3 in portlet web-inf/lib
To make a clear and reproducible example i restarted with petportal sample portlet from spring.

Problem:
Trying to add session or globalSession scoped beans to petsites-portlet controller (PetSitesRedirectController). In this case (example) I would like to add a favourite petsite bean backed by spring:

from petsites-portlet.xml

  <bean id="fav" class="org.springframework.samples.petportal.domain.PetSite" scope="session">
  	<aop:scoped-proxy/>
  </bean>
  <bean class="org.springframework.samples.petportal.portlet.PetSitesRedirectController">
    <property name="petSites" ref="petSites"/>
    <property name="favourite" ref="fav"/>
  </bean>

In the PetSitesRedirectController I only added getter and setter for favourite property.

In web.xml i have tried the following things in separatley and in combination:

1. add a listener:

 	<listener>
		<listener-class>
			org.springframework.web.context.request.RequestContextListener
		</listener-class>
	</listener>

2. add a filter:

<filter> 
    <filter-name>requestContextFilter</filter-name> 
    <filter-class>org.springframework.web.filter.RequestContextFilter</filter-class>
  </filter> 
  <filter-mapping> 
    <filter-name>requestContextFilter</filter-name> 
    <url-pattern>/*</url-pattern>
  </filter-mapping>

3. Filter with diffrent mapping

	<filter>
		<filter-name>requestContextFilter</filter-name>
		<filter-class>
			org.springframework.web.filter.RequestContextFilter
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>requestContextFilter</filter-name>
		<servlet-name>petsites</servlet-name>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>INCLUDE</dispatcher>
		<dispatcher>FORWARD</dispatcher>
	</filter-mapping>

In all above cases I get the following error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.portlet.mvc.annotation.DefaultAnnotati
onHandlerMapping#0' defined in PortletContext resource [/WEB-INF/context/petsites-portlet.xml]: Initialization of bean failed; nested exception is org

What am I missing?

Well, I've nearly the same problem with my globalSession in WebSphere Portal. Did anyone find a solution?

Have you found the solution for this?
