java - struts2 conventions plugin not working properly -

i trying run application convention plugin struts2. application fine struts.xml configured this:

<struts>      <package name="struts2demo" extends="struts-default">     <action name="hey" class="action.countryaction" method="get">        <result name="success">/index.jsp</result>     </action>     <action name="add" class="action.countryaction" method="add">        <result type="redirect" name="success">hey</result>     </action>     <!-- add actions here -->     </package>  </struts> 

now removed struts.xml , added annotations this:

@namespace("/") @resultpath(value="/") public class countryaction extends actionsupport implements modeldriven<country>{     private list<country> worldcountry;     private country country = new country();        public country getcountry() {             return country;         }      public void setcountry(country country) {             this.country = country;         }   //   httpservletrequest request; @action(value="/hey",results={@result(name="success",location="/index.jsp")})     public string get() throws sqlexception     {         countryservice cs = new countryservice();         setworldcountry(cs.getcountry());       //  system.out.println(getworldcountry());         return success;     }       public list<country> getworldcountry() {         return worldcountry;     }      public void setworldcountry(list<country> worldcountry) {         this.worldcountry = worldcountry;     }      @override     public country getmodel() {         return country;     } } 

but when trying run application getting following error:

messages:

there no action mapped namespace [/] , action name [hey] associated context path [/juststruts2]. 

my web.xml this:

<filter>         <filter-name>struts2</filter-name>         <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class>         <init-param>          <param-name>struts.devmode</param-name>          <param-value>true</param-value>       </init-param>     </filter>      <filter-mapping>         <filter-name>struts2</filter-name>         <url-pattern>/*</url-pattern>     </filter-mapping> 

where doing wrong, appreciated.
regards.

according message struts inform [hey] not found in action configuration. in struts.xml defined without slash. same in annotation. don't map index.jsp handled container not struts2. name "success" used default, it's not necessary.

@action(value="hey", results = { @result(location="/page.jsp") }) 

note @resultpath not necessary.
