RE: Help me how to exposing service and consume it

Looks like the Javadoc of the service(ServiceManager) method of the component that uses the services is wrong. Here you are a service method that works 

  /**
   * Servicing of the component by the container during 
   * which service dependencies declared under the component
   * can be resolved using the supplied service manager.
   *
   * @param serviceManager the service manager
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.random.RandomGenerator:1.0"  key="random"
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.identity.Identifiable"  key="simple"
   */
  public void service(ServiceManager serviceManager) throws ServiceException {
    getLogger().debug("[service start]");
    
    serviceManager.lookup("random");
    serviceManager.lookup("simple");
    
    getLogger().debug("[service end]");
  }

And this is a service method that fails

  /**
   * Servicing of the component by the container during 
   * which service dependencies declared under the component
   * can be resolved using the supplied service manager.
   *
   * @param serviceManager the service manager
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.random.RandomGenerator:1.0"  key="random"
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.identity.Identifiable" NOTE HOW I FORGET THE KEY
   */
  public void service(ServiceManager serviceManager) throws ServiceException {
    getLogger().debug("[service start]");
    
    serviceManager.lookup("random");
    serviceManager.lookup("simple");//THIS WILL FAIL AT RUNTIME
    
    getLogger().debug("[service end]");
  }


To make the previous method work you need to lookup by interface name, not by key

  /**
   * Servicing of the component by the container during 
   * which service dependencies declared under the component
   * can be resolved using the supplied service manager.
   *
   * @param serviceManager the service manager
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.random.RandomGenerator:1.0"  key="random"
   * @avalon.dependency type="avalon.merlin.service.manual.interfaces.identity.Identifiable"
   */
  public void service(ServiceManager serviceManager) throws ServiceException {
    getLogger().debug("[service start]");
    
    serviceManager.lookup("random");
    serviceManager.lookup(Identifiable.class.getName());
    
    getLogger().debug("[service end]");
  }
