Migration: webwork to struts2 help.
Hi Guys,
Can i ask some help regarding migration from webwork to struts2 ?
Here's the error i'm getting after i made some changes for the migration..
INFO org.apache.struts2.spring.StrutsSpringObjectFactory - Initializing Struts-Spring integration...
18192 [WrapperSimpleAppMain] ERROR org.apache.struts2.spring.StrutsSpringObjectFactory - ********** 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>

<!-- config contextLoaderListener to extract spring config params -->
web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Register your objects via the Spring configuration
<!--spring manages com.my.BarClass as id ="bar" -->
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="autodetect">
<bean id="bar" class="com.my.BarClass" singleton="false"/>
...
</beans>
<!-- The singleton attribute is set to false, meaning that Spring will create a new Action class upon each request, as Struts 1 would do. -->
<!-- works well for stateful beans which carry new information for each request-->
<!-- struts.xml maps URI -> action -> Spring bean -->
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-default.xml"/>
<package name="secure" namespace="/secure" extends="default">
<action name="bar" class="bar">
<result>bar.ftl</result>
</action>
</package>
</struts><!--action name="bar" maps class="Bar" to bean id="bar" which is a stateful Bean called BarClass whose params are extracted by spring ContextLoaderListener -->

(replace all refs to Tapestry or JSF with Struts)

If you're using Spring, do you have that?
If you're not, the Struts 2 Spring plugin from your app.
