How do you declare the action in struts.xml? Because instead full
class name you must use the id from applicationContext.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd";>
<struts>
<package name="secure" namespace="/secure" extends="default">
<action name="user" class="userAction">
<result>success.jsp</result>
</action>
</package>
</struts>
