웹프로그래밍을 하면서 오류 내용 중에 classpath 혹은 ojdbc 이라는 용어가 나온다면 JDBC 연결이 안되서 생기는 경우를 생각해봅시다.
밑에 사진같은 경우에는 spring / mybatis / tomcat / oracle 환경에서 오류가 난 것입니다.
해결방법
1. DBMS에 따른 jdbc 드라이버를 jdk에 복사 해둔다.
탐색기 - C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib
- 주소에서 두개의 파일 중 ojdbc14 복사하기
2. jdk 설치된 곳으로 감
두군데에 붙여 놓기 해야함
C:\Program Files\Java\jdk1.8.0_73\jre\lib\ext
- 주소에 붙여놓기
C:\Program Files\Java\jre1.8.0_73\lib\ext
- 주소에 붙여놓기
오류내용 - 두가지
