톰캣이 자꾸 죽습니다..
원인을 모르겠어요.. 갑자기 어느날 보면

어느 한순간 이러기 시작하니 감이 안 잡히네요..
혹시 원인을 알기 위해 어떤 부분을 더 살펴봐야 할까요?
Forums:
tomcat의 설정 파일나
tomcat의 설정 파일나 tomcat이 실행되는 환경 변수에 classpath가 어떻게 잡혀있는지 확인해보세요.
classpath에 걸려있는 jar나 zip을 찾으려고 하는데, 정작 파일은 없고 디렉토리만 있다든가 하면
이런 에러가 발생할 수 있습닌다.
감사합니다....
답변 감사합니다.. 하지만 이런 일이 발생하는 것이 항상이 아니라 약 몇주간 잘 동작을 하다 발생한다는 것이 문제인데요..
발생시점의 아파치로그를 봐도 중구난방이라.. 특정 jar를 못 찾는다거나 하는 문제로 생각하기 어렵다는 것으로 생각되기는 합니다..
그래도 한번 더 jar의 classpath를 확인해보는게 맞겠네요.. 감사합니다..
혹 다른 힌트가 생각나신다면 조언 부탁드리겠습니다(__)
오호호호호호호홋!!!!
JAR 파일 상태를 체크 해보세요
가끔 JAR 파일이 압축이 안풀려서 발생하는 거 일수도 있습니다. 한번 JAR 파일들 압축을 풀어보세요.
감사합니다.
한가지 궁금한 게 있는데요..
혹시 평소에 잘 풀리다가 어떤 환경적인 요인으로 인해서
원래 풀 수 있던 jar를 갑자기 못 풀게 되는 경우가 있을까요?
오호호호호호호홋!!!!
