넷빈즈/지속성 API 오류

Question

나는이 자습서를 따라하고, 내가 사용 넷빈즈 http://www.netbeans.org/kb/docs/java/gui-db-custom.html

난에 나는 "데이터베이스에서 새 개체 클래스"를 만들 부분에 도착 6.5.1 " 튜토리얼의 "마스터/상세보기 사용자 정의"절을 참조하십시오. 작업 목록에서이 오류가 발생하여 컴파일 할 수 없습니다. 실행하면 런타임 오류가 발생합니다 ... Atleast 나는이 두 가지가 관련 있다고 생각합니다.

 
Error Named queries can be defined only on an Entity or MappedSuperclass class. Countries.java 27 C:/Users/Danny/dev/NetBeansProjects/Test/src/test 

Error Named queries can be defined only on an Entity or MappedSuperclass class. Products.java 28 C:/Users/Danny/dev/NetBeansProjects/Test/src/test 

내가하는 모든 작업은 데이터베이스의 새로운> 엔티티 클래스를 수행하고 튜토리얼에서 말한대로 수행합니다. 튜토리얼 작성자는 응용 프로그램이 "부분적으로 기능적"이어야한다고 말했기 때문에 "대화 상자 추가"제목에서 튜토리얼을 멈추었습니다. 생성 된 코드를 내가 지시 한 바를 편집하지 않았습니다.

내가 잘못 또는 뭔가해야 내 넷빈즈 응용 프로그램을 생각하고, 나 자신

를 같은 문제를 가진 사람을 찾을 수가 없습니다

Answer 1

netbeans에 버그가있는 것으로 보입니다. 새로 설치 했으므로 이제는 작동하는 것 같습니다.

Answer 2

동일한 문제가있었습니다. 다시 설치 - 동일한 문제가 발생합니다. Ran Revo 제거 프로그램이 기본 설정으로되어 있습니다. 다시 설치되었습니다. 이번에는 새 프로젝트 마법사 직후에 바로 제품 테이블을 & 국가에 대해 만들었습니다. 그것이 차이를 만들지 모르겠지만, 이번에는 모두 잘했다.

Answer 3

Netbeans IDE 업데이트가 효과적입니다. 나는 신선한 설치가 필요하지 않았다.

Answer 4

업데이트 :이 오류는 Netbeans 7.4에도 여전히 존재합니다.
엔터프라이즈 응용 프로그램의 -war (Web -) 모듈 내의 Annotated Entities가 여전히 "NamedQueries를 정의 할 수 없습니다 ..."오류를 발생 시키므로
ejb-Module의 동일한 클래스는 그렇지 않습니다.
분명히 엔티티 클래스가 있어야합니다.
JSF - 페이지를 생성하기 위해 웹 모듈로 이동했습니다.하지만이 문제로 인해 페이지가 다시 시작된 후
문제가 발생하여 제대로 작동하지 않았습니다. EJB 모듈에서도 생성 될 수 있습니다.
