java.lang.NoSuchMethodError : org.json.JSONObject.getNames 예외

Question

프로젝트의 빌드 경로에 www.java2s.com/Code/Jar/j/Downloadjavajsonjar.htm에서 다운로드 한 필수 JAR 파일을 포함 시켰습니다.

그러나이 오류를 해결할 수 없습니다. 그 밖의 무엇이 문제를 일으킬 수 있습니까?

Answer 1

당신이 당신의 프로젝트 빌드 경로에 항아리를 추가 한 수 있지만, 당신은 톰캣에 배포 된 전쟁으로 그것을 번들되지 않습니다

내 스택 추적은 다음과 같습니다. 편집 : 이전 버전의 jar 파일을 번들하거나 jar 이전 버전을 애플리케이션 클래스 경로에서 볼 수 있습니다.
