프로젝트 서버 배포시 에러

안녕하세요 그동안 강의 너무 잘 들었습니다.

다름이 아니라 제가 이 강의를 통해 들은 프로젝트를 서버를 통해 올려 보려고 하는데, 에러가 계속 발생하여 도제히 모르겠어서 질문드립니다.

현재 aws를 활용하여 rds,mysql을 활용하여 db연동시킨후,ec2를 이용해 배포를 하려했습니다.

계속 진행되지 않아 일단, 우분투 서버에서의 jdk및 환경변수설정 등 여러가지를 완료하였으나 계속 에러가 발생합니다.

그래서 또 제 다른컴퓨터에 자바ide만깔려있는 곳에서도 실행했는데 여긴 구동되고 이 서버에서만 에러가 발생하여 여러밤을 꼬박 새었습니다.ㅜㅜ

(죄송합니다 사진이 역순으로 된거 같아요!)
