Struts2 can not find index

Good morning, I'm doing a small project with the new version Struts 2.5.13 and following the guide official I can not get it started. (Error 404, can not find resource).

ACTION An action as simple as possible:

@SuppressWarnings("serial")
public class InitAction extends ActionSupport implements SessionAware{


   @Override
   public String execute()
   {
      String resultado="success";       
      System.out.println("Holaaa resul("+resultado+")");

      return resultado;
   }
}

struts.xml

<constant name="struts.devMode" value="true" />

<package name="default" extends="struts-default">        
    <action name="init" class="com.mncars.commons.actions.InitAction">
        <result name="success">/index.jsp</result>
    </action>
</package>

Web.xml

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

Index.jsp

   HttpSession ses = request.getSession();
   response.sendRedirect("init");
