Hi All,
We've are trying to use Struts2 with Spring2 on Webspher 6.1 and JDK 1.5.
Basically we are trying to use session scoped beans from Spring
applicationContext in to Struts2 using Spring DI. but running in to issue.
Following are my config files:
web.xml
==========================================================================================
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
==================================================================================================
Spring applicationContext.xml
==========================================================================================
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";

<bean id="mVO" class="com.foo.bar.vo.MyVO" scope="session">
<aop:scoped-proxy/>
</bean>
<bean id="myInterceptor" class="com.foo.bar.interceptors.MyInterceptor">
<property name="mvo">
<ref local="mVO" />
</property>
</bean>
..................
=============================================================================================
When I run this configuration, I am getting following error:

======================================================================================================
As per above error message, I changed web.xml to have
org.springframework.web.context.request.RequestContextListener instead of
ContextLoaderListener but that cause Struts2 to fail with following error:
==================================================================================================================================================
[1/19/08 0:54:47:605 EST] 00000032 StrutsSpringO E
org.apache.commons.logging.impl.Jdk14Logger fatal ********** FATAL ERROR
STARTING UP STRUTS-SPRING INTEGRATION **********
Looks like the Spring listener was not configured for your web app!
Nothing will work until WebApplicationContextUtils returns a valid
ApplicationContext.
You might need to add the following to web.xml:
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
===================================================================================================
So, not sure what am I missing here. Is it a case that, Spring wants us to
use RequestContextListener for session scoped beans but Struts2-spring
plugin will not allow us to use other than ContextLoaderListener.
I tried old mailing list archives and did search on google but could not
find any solution to this problem.
So, please help me here.
Thanks in advance..
