我想用治註冊表API來註冊服務，寫下這樣的代碼：如何使用治理API將服務註冊到WSO2治理註冊表？
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();
它的工作原理和服務可以在Web的用戶界面上找到。
的話，我想用org.wso2.carbon.discovery.client.DiscoveryClient類探測這種服務，像這樣：
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);
}
但有例外：

我錯過什麼？提前致謝！
