Hi All,
I am using RAD7.0, JDK 1.5, Struts2 and Spring 2.x. We have been using
Struts1.x and Spring 1.x for a long time now and moving our app to Struts2 +
Spring2
We are trying to have Spring manage all the value objects and action
objects. And so followed steps in Struts document to add struts2-spring
plugin jar and made necessary changes but getting errors when try to create
a bean in session scope. Following are my configuration files:
web.xml
==================================================================================================================================================

With this configuration, server starts up correct without any issues, but
when I try to access my action class, I am getting following error:

So, I tried changing web.xml and replace
org.springframework.web.context.ContextLoaderListener with
org.springframework.web.context.request.RequestContextListener. At that
point, server starts up correctly, but while accessing action class, I am
getting error message saying :
[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>
It looks like, Struts2 only works with ContextLoaderListener, but Spring2
requires to use RequestContextListener if you are using session/request
scoped bean in Servlet 2.4+.
I tried to search on mailing archive but didn't find any solution.
Can somebody please help if they have tried implementing session/request
scoped beans using Spring2 with Struts2?
Thanks a bunch in advance.
