거버넌스 API를 사용하여 WSO2 거버넌스 레지스트리에 서비스를 등록하는 방법은 무엇입니까?

Question

나는, 지배 레지스트리 API를 사용하여 서비스를 등록 할이 같은 코드 작성 :

ServiceManager serviceManager = new ServiceManager(registry); 
    Service newService = serviceManager.newService(new QName("http://services.talend.org/ReservationService", "ReservationServiceProvider")); 
    newService.addAttribute("endpoint", "http://localhost:8040/services/ReservationServiceProvider"); 
    newService.addAttribute("metadataVersion",String.valueOf(1)); 

    String scope = "http://com.talend/Reservation"; 
    URI[] scopes = new URI[] { URI.create(scope) }; 
    newService.setAttributes("scopes", Util.toStringArray(scopes)); 

    String address1 = "http://localhost:8040/services/ReservationServiceProvider"; 
    String address2 = "https://localhost:9001/services/ReservationServiceProvider"; 
    URI[] xAddresses = new URI[] { URI.create(address1), URI.create(address2) }; 
    newService.setAttributes("xAddresses", Util.toStringArray(xAddresses)); 

    serviceManager.addService(newService); 
    //newService.activate(); 

그것은 작동 및 서비스는 웹 UI에서 찾을 수 있습니다.

public String[] lookupEndpoints(String scope) throws DiscoveryException{ 
    URI[] scopes = new URI[] { URI.create(scope) }; 
    TargetService[] services = client.probe(null, scopes); 
    if (services != null && services.length > 0) { 
     URI[] endpoints = services[0].getXAddresses(); 

     if (endpoints != null && endpoints.length > 0) { 
      String[] returnEps = new String[endpoints.length]; 
      for (int i =0; i< endpoints.length; i ++){ 
       returnEps[i] = endpoints[i].toString(); 
      } 
      return returnEps; 
     } 
    } 
    throw new DiscoveryException("Unable to locate a service for the scope: " + scope); 
} 

하지만 예외 가지고 :

다음,이 같은 org.wso2.carbon.discovery.client.DiscoveryClient 클래스를 사용하여이 서비스를 조사 할 내가

를 놓친 건가 어떤 것? 미리 감사드립니다!

이러한 서비스는 실제 서비스 끝점 (예 : 응용 프로그램 서버에서 호스팅 됨)이 아닙니다. 거버넌스 레지스트리에서 실제 서비스의 계약 세부 정보 (wsdl, 정책, 스키마, 끝점 ... 등)를 저장합니다.
