GlassFish 3.1.1을 사용하고 있습니다. 및 NetBeans 6.9.1. NetBeans에서 웹 응용 프로그램을 만들고 엔티티 클래스를 생성했습니다. 내가 추가 한 것은 @GeneratedValue 주석뿐입니다. 다음은 코드입니다.알 수없는 bean 엔티티 클래스 - Glassfish 및 NetBeans의 오류

그런 다음 Entity 클래스 용 JPAController 클래스를 생성했습니다.

다 될 때까지 괜찮 여기에 코드입니다 내 JSF에서이 방법을 사용하려고하면 지금, 그러나 콩 관리 :

cfg.setBackuppath("foo");
CdrConfigJpaController cjc = new CdrConfigJpaController();
cjc.create(cfg);
Record rec = new Record();
RecordJpaController rjc = new RecordJpaController();
rjc.create(rec);
RecordColumn col = new RecordColumn();
col.setColumnname("foo1");
col.setRecord(rec);
RecordColumnJpaController rcjc = new RecordColumnJpaController();
rcjc.create(col);
} catch (Exception ex) {
Logger.getLogger(FileWorkerBackup.class.getName()).log(Level.SEVERE, null, ex);
}
}
나는 오류 다음 얻을 :

구글에서 "모듈에 모든 엔티티 클래스 포함"체크를하는 것이 도움이되는 경우가 있습니다. 그런 다음 테이블 간 크로스 db 참조에 대한 오류가 발생합니다. 나는 이것을하려고하지 않고있다). 글래스 피쉬를 다시 시작하는 것이 (폐쇄 세션으로 인해 풀리지 않음) Google에서 발견되었지만 도움이되지 않습니다. 제발, 올바른 방향을 가르쳐주세요.
