playframework - Scala play Guice injection -

i'm using scala play 2.5 , have following error while trying inject object in 1 of controllers. i'm using default injection framework given play guice.

    provisionexception: unable provision, see following errors:      1) no implementation services.myservice bound.      while locating services.myservice parameter 0 @ controllers.mycontroller.<init>(mycontroller.scala:12)      while locating controllers.mycontroller parameter 3 @ router.routes.<init>(routes.scala:55)      while locating router.routes      while locating play.api.inject.routesprovider while locating play.api.routing.router parameter 0 @ play.api.http.javacompatiblehttprequesthandler.<init>(httprequesthandler.scala:200)      while locating play.api.http.javacompatiblehttprequesthandler      while locating play.api.http.httprequesthandler parameter 4 @ play.api.defaultapplication.<init>(application.scala:221) @ play.api.defaultapplication.class(application.scala:221)  while locating play.api.defaultapplication      while locating play.api.application 

here controller:

package controllers  import services.myservice  class mycontroller @inject()(myservice: myservice, val messagesapi: messagesapi) extends controller i18nsupport {      def somefunctionthatusesmyservice(url: string) = action {} } 

here service inject:

package services  import javax.inject._  trait myservice {     def op(param1: string, param2: string): boolean }  @singleton class basicmyservice extends myservice {     override def op(param1: string, param2: string): boolean = true } 

that how i'm using it:

@singleton class homecontroller @inject() extends controller {    /**    * create action render html page welcome message.    * configuration in `routes` file means method    * called when application receives `get` request    * path of `/`.    */   def index = action {     //ok(views.html.index("your new application ready."))     redirect(routes.mycontroller.somefunctionthatusesmyservice(some(routes.othercontroller.welcomepage().url)))   }  } 

you should add implementedby annotation service trait

package services  import javax.inject._  @implementedby(classof[basicmyservice]) trait myservice {     def op(param1: string, param2: string): boolean }  @singleton class basicmyservice extends myservice {     override def op(param1: string, param2: string): boolean = true }
