음.... 게시판을 리스트를 불러오는 곳에서 오류로.... 고생하고 있습니다.
일단 에러 로그를 보여드릴게요
Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: 4

음.... String index out of range : 4인거로 바서 분석을 해보면
ex)길이가 2인 배열에 즉 0, 1, 2 이렇게 주소가 있으면 여기를 넘어서 다른 주소를 참조하여 생기는 문제인거 같은데요...
아래는 list를 수행하는 소스입니다... 음.... 사실 에러는 얼추 이해가 되는뎅.... 게시판이 처음이다보니... 어디가 적확하게 문제인지
분석이.... 모자랍니다... 형님들 한수부탁드려요...ㅠㅜ
