하이버네이트를 실행하기 위해서는 hibernate4.2.3.jar 파일 뿐 아니라 lib 폴더의 각종 jar 파일이
필요하다.
물론 이클립스 하이버네이트 플러그인을 설치해도 된다. 현재 Eclipse INDIGO 까지 나와 있다.

2. 준비
이클립스 ? Spring Project
hibernate4 및 spring 관련 라이브러리 추가
(하이버네이트4 의 경우 스프링 3,1 이상이 필요)
(하이버네이트4 의 경우 스프링 3,1 이상이 필요)
주) 스프링의 Template Project에서 hhibernate Template을 이용하여 하이버네이트 APP 작성가능하나
라이브러리 버전이 맞지 않아 hibernate4 예제와 연동 어려움
예제 테이블 작성

empno number ,
