Struts2 를 실행하려고 준비 하다 보면 여러가지 에러를 피하지 못하는 경우가 많다. 어찌 보면 튜토리얼을 보고 제대로 시작을 한다면 모르지만 아마도 나와 같은 사람들이 많다는 생각을 해보면서 여기저기에 샘플들을 모아서 새로운 것을 만들다 보니 놓치게 된것이 바로 Jar 파일의 유무와 버전에 대한 문제가 있다는 것을 간과 했다.
아래의 에러에 대한 해결책은 버전과 필수 파일을 맞추는데서 부터 시작 한다.
위의 경우는 Struts2 2.3.16 버전에서 기본 Lib 파일을 다운로드 받은 후 기본적으로 필요한 것만 받은 것이다. 이 중엥서 log4j-1.2.16.jar, ojdbc6.jar 파일은 나의 사황에 맞추 추가된 내용이므로 받드시 필요 한것은 아니다.
