"appengine"유형의 사용 가능한 StoreManager가 없습니다. 관련 DataNucleus 저장소 플러그인을 CLASSPATH에 넣었는지 확인하고 JNDI 또는 DataSource를 통해 연결을 정의하는 경우 지속성 속성 "datanucleus.storeManagerType"도 제공해야합니다."appengine"유형의 사용 가능한 StoreManager가 없습니다.

시도 할 때 위 오류가 나타납니다. 객체를 지속시킨다. 누구든지 어떤 제안이 있습니까?

내 POM 및 jdoconfig은 다음과 같습니다 : 유형 "에서 appengine"의 사용 가능한 StoreManager가 없습니다

따라서 GAE/Datastore에서 지속하려면 CLASSPATH에 "datanucleus-appengine"항아리를 넣지 마십시오. 메시지가 분명합니다.

. 관련 DataNucleus 스토어 플러그인을 CLASSPATH에 넣었는지 확인하고 JNDI 또는 DataSource를 통해 연결을 정의하는 경우 지속성 속성 "datanucleus.storeManagerType"을 제공해야합니다.
