Struts를 사용하지 않지만 Google에서는 [상당히 많은 히트 수]를 제공합니다 (http://www.google.com/search?q=%22java.lang.NullPointerException+at+org.apache.struts.action. ActionServlet.parseModuleConfigFile % 22)에 대한 예외입니다. 그들 중 일부는 도움이 될 수 있습니다. – BalusC
설정 파일에있을 가능성이 높습니다. 우리는 볼 수 없습니다. 그것을 보면서 명백하지 않은 경우, 일반적으로 구성 오류가있는 곳을 격리하려고 큰 덩어리를 주석으로 시작합니다. –
최근 새 모듈을 추가하는 동안이 문제가 발생했습니다. 우리가 찾은 것처럼 web.xml에는 새로운 모듈 struts config 매핑이 포함되어 있지만 실제 파일은 해당 위치에 없습니다.
