java - Declarative OSGi Services -

-

i have question declarative osgi services. have following interface : 

  public interface printservice {     public void print();   }

and implementation: 

    public class printserviceimpl implements printservice {        @override       public void print() {         system.out.println("hello printserviceimpl!");       }     }

osgi-inf/component.xml :

<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" name="service">    <implementation class="service.printserviceimpl"/>    <service>       <provide interface="print.printservice"/>    </service> </scr:component>

manifest.mf :

service-component: osgi-inf/component.xml

after install service , start nothing happend. how can activate , print "hello printserviceimpl!" console.

why expect print method invoked? part of interface of service, not invoked until can client binds , calls it.

if type services command in console should see bundle publishing print.printservice service; means component working. if don't see may missing scr bundle suggested tom seidel in comments above.
