Karaf 컨테이너에 배포 된 OSGi 응용 프로그램에서 PostgreSQL에 연결

StackOverflow https://stackoverflow.com//questions/23057562

문제

karaf 2.3.4 컨테이너에서 PostgreSQL에 연결하려면 Hibernate를 사용하고 있습니다. 내 번들을 배포 할 때 javax.naming.nameNotFoundException OSGi : Service / javax.sql.dataSource / "(osgi.jndi) .service.name= jdbc / postgresds).

여기에 내 persistance.xml 파일이 있습니다

이 문제를 해결했으며, 나는 M. Cristian으로 파일 목록을 업데이트했지만 다른 이상한 문제는 : KARAF를 다시 시작하고 KARAF 콘솔을 통해 데이터를 삽입하려고 시도한 콘솔 인쇄 : 이는 활성 트랜잭션이 아니므로 EntityManager를 사용하여 다른 방법을 시도했으며 문제는 더 이상 나타나지 않습니다.

도움이 되었습니까?

해결책

지속 장치가 사용되는 동일한 청사진 컨텍스트에 DataSource가 게시 될 때 코드가 작동하지 않습니다.

문제는 청사진이 EnitityManagerFactory 서비스가 주입 될 때까지 기다릴 것입니다.그래서 데이터 소스는 절대로 게시되지 않습니다.ARIES JPA는 번들에 대한 엔터티 ManagerFactory를 만들어야하지만 DataSource를 찾으려고 노력하는 시간 초과는 할 수 있음을 감지합니다.

그래서 DataSource를 스피어레이트 번들에 넣고 작동해야합니다.
