서버 셋팅을 마치고 재대로 돌아가던 서버가 코드를 수정하고 서버를 돌리니 다음과 같은 메세지를 웹상에서 내뱉었다.

root cause

http 에러코드가 500 인걸로 봐서 내부 서버 오류라고 하는데 도대체 어떤점이 잘못됬는지 모르겠다.

500 :Internal server error (내부 서버 오류)

해결

SQL쪽에 문제가 있는 것 같아 datasource 쪽을 보니 아이디 비밀번호를 입력하는 칸이 있었다.

결론부터 말하자면 아이디를 잘 못 적었던 것이다. 

            

패스워드는 동일 하게 적었으나, 오라클이다보니 아이디를 system, sys 로 적었던 것이 문제 였다.

datasource.xml 에 적은 username과 오라클의 접속 ID가 같아야했던 것이었다.
