OrientDB를 Java 애플릿에서 실행하십시오.

EDIT : 해결책을 찾았습니다. 메이븐 빌드 프로세스 동안 코드를 최소화하는 것이 문제였습니다. Java Applet에서 OrientDB를 실행할 수 있습니다.OrientDB를 Java 애플릿에서 실행하십시오.

자바 애플릿에서 내림차순 OrientDB를 시작하는 데 문제가 있습니다. OrientDB 버전 1.0.1이있는 서명 된 애플릿을 사용합니다. 누군가가 OrientDB를 애플릿에 구현했는지, 이것이 가능한지 또는이 예외로 나를 도울 수 있는지 확인할 수 있습니까?

예외 내가 얻을 :

내 애플릿 코드는 DB를 시작합니다 :

public class Applet extends java.applet.Applet { 

    OrientDbConfigurationLoader configLoader = null; 
    OServer server = null; 
    ODatabaseDocumentTx db = null; 

    @Override 
    public void init() { 
     AccessController.doPrivileged(new 
       PrivilegedAction<OServer>() { 

      public OServer run() { 
       configLoader = new OrientDbConfigurationLoader("db/", "test"); 

       try { 
        server = OServerMain.create(); 
        server.startup(configLoader.loadDefaultConfig()); 
        server.activate(); 
       } catch (InstanceAlreadyExistsException e) { 
        server = OServerMain.server(); 
       } catch (Exception e) { 
        System.out.println("Something went wrong while the server should start"); 
        e.printStackTrace(); 
       } 

       try { 
        db = new ODatabaseDocumentTx("memory:temp"); 
        db = db.open(OrientDbConfigurationLoader.USERNAME, OrientDbConfigurationLoader.PASSWORD); 
       } catch (Exception e) { 
        System.out.println("Can't init the in-memory db."); 
        e.printStackTrace(); 
       } 
       return null; 
      } 
     }); 
    } 
}

문제는 자바 서비스 레지스트리의 사용을 보인다. 난 그냥 SVN 트렁크 (r5909)이 체크 추가 한

ServiceRegistry.lookupProviders(clazz);

OClassLoaderHelper.lookupProviderWithOrientClassLoader()

가 호출 봐 이런 식으로 A의

try { 
      factories.add(ite.next()); 
     } catch (Exception e) { 
      OLogManager.instance().warn(null, "Cannot load OCommandExecutorSQLFactory instance from service registry", e); 
     }

를 덤프 WARN을하지만, 필요한 경우 자신의 공장을 계속 구성 할 수 있습니다.
