    <package name="hello" namespace="/" extends="struts-default">
        <action name="hello">
            <result>/Hello.jsp</result>
        </action>
    </package>

    <package name="resultTypes" namespace="/r" extends="struts-default">
        <action name="r1">
            <result type="dispatcher">/r1.jsp</result>
        </action>

        <action name="r3">
            <result type="chain">r1</result>
        </action>

        <action name="r4">
            <result type="chain">
                <param name="actionName">hello</param>
                <param name="namespace">/</param>
            </result>
