struts2 result The requested resource is not available

I have a login page and a login action. When user logins action return "success" result. and it must go to another action. But I get the following error:

HTTP Status 404 - /ESA/protected/admin/list
description The requested resource is not available.

this is my struts.xml file : 

    <action name="login" class="ir.imrasta.esa.ui.action.UserAction" method="login">
        <result name="success">protected/admin/list</result>
        <result name="failed">/login.jsp?login=failed</result>
    </action>

    <action name="/protected/admin/list" class="ir.imrasta.esa.ui.action.ManagerAction" method="list">
        <result name="success">/protected/admin/list.jsp</result>
    </action>

see <result name="success">/protected/admin/list</result> in above code. if i change it with a jsp page it work fine.

In order to redirect to another action you need to use redirectAction result type.

<action name="login" class="ir.imrasta.esa.ui.action.UserAction" method="login">
    <result name="success" type="redirectAction">protected/admin/list</result>
    <result name="failed">/login.jsp?login=failed</result>
</action>

And slashes in action names are not allowed by default. To allow slashes in action names you need to set struts.enable.SlashesInActionNames constant to true in struts.xml file.

<constant name="struts.enable.SlashesInActionNames" value="true" />

See even the action class which you are referring too also needed to be mapped in struts.xml, the reason you are getting 404 is that the action class which you are finding is not having any mapping found in struts
