* 오류7

프로덕션 환경들에서 최적의 성능을 제공하는, APR 기반 Apache Tomcat Native 라이브러리가, 다음 java.library.path에서 발견되지 않습니다

https://hermeslog.tistory.com/432

헤르메스님 블로그에 따르면 로컬환경에서 톰캣이 떴을 때 나는 오류가 아님,  외부환경과 내 톰캣이 연결될때 사용하는 부분이라 로컬에서 필요치 않으니 무시해도 되는 에러메세지라고 함

거슬리면 xml 에 해당 부분을 주석처리 하여 오류가 안뜨게 할 수 있다고 함

하지만 나는 그냥 냅두기로 함

근데... 왜 고양이 안뜨지....
