JPA 지원을 사용하여 OSGI 번들에 액세스 할 때 java.lang.NoClassDefFoundError : javax/naming/NamingException이 발생 함

Question

OpenJPA를 JPA 공급자로 사용하고 있습니다. JPA2.0을 지원하는 작은 OSGI 번들 프로젝트를 만들었습니다. 이 번들은 클라이언트에 지속성 기능을 제공합니다.

위의 지속성 서비스를 사용하기 위해 다른 클라이언트 번들을 만들었습니다. 나는 울부 짖는 오류를 얻고있다 펠릭스 프레임 워크를 사용하여 클라이언트 번들 서비스,

java.lang.NoClassDefFoundError가 시작할 때 : javax의/이름을/NamingException를

나는 OSGI 번들 발전에 아주 새로운 오전. 이 문제를 해결하도록 도와주세요.

Answer 1

클라이언트 번들은 javax.naming 패키지를 가져와야합니다. Import-Package으로 표시된 가져온 패키지 목록에 추가하십시오.

그러나 javax.naming을 사용하여 문제를 해결 한 후에 추가 종속성이 누락 될 수 있습니다. 오류가 발생하기 쉽고 중복 된 정보가 포함되어 있으므로 MANIFEST.MF를 직접 작성해서는 안됩니다. bnd 또는 Bndtools과 같은 도구를 사용해야합니다.

업데이트 : 스택 트레이스의 아래 부분에 도시 된 바와 같이는 실제로는 OpenJPA 자체 패키지 javax.naming를 가져올 실패 "javax.naming.NamingException org.apache.openjpa가 [109]에서 찾을 수 없습니다."

따라서 OpenJPA가 손상되었습니다.

Answer 2

종속성으로 javax.api를 추가하려고합니다.

<dependencies> 
    <module name="javax.api"/> 
</dependencies>
