using action in welcome file list

Hi All,

I am trying to user struts2 action in my welcome file list of web.xml here
is the entry

 <filter>
        <filter-name>action2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>

          <filter-name>action2</filter-name>
          <url-pattern>/*</url-pattern>
          <dispatcher>REQUEST</dispatcher>
         <dispatcher>FORWARD</dispatcher>
         <dispatcher>INCLUDE</dispatcher>
         <dispatcher>ERROR</dispatcher>
    </filter-mapping>

 <welcome-file-list>
        <welcome-file>welcome</welcome-file>
      </welcome-file-list>

here is the entry in my struts.xml file

<package name="default" extends="struts-default">
<action name="welcome">
