java.lang.ClassCastException가 바람둥이 로딩 서블릿을 시작할 때

Question

SWT 애플리케이션 내에서 임베디드 Tomcat 웹 응용 프로그램을 시작하려고 할 때, 나는 (아래 스택 트레이스) 오류를 받고 있어요 :

java.lang.ClassCastException가를 : org.apache.struts.action.ActionServlet 및 java.lang.ClassCastException가 : org.apache.jasper.servlet.JspServlet

은 내가 /lib 디렉토리/ 디렉토리에있는 항아리의 모든 통해 검색 한 및 /WEB-INF/lib 디렉토리에 존재하며 Servlet 클래스에 대한 중복 참조를 찾지 못했습니다.

응용 프로그램은 응용 프로그램의 소스 코드를 빌드하고 오류없이 성공적으로 컴파일 톰캣 6.0.36 및 스트럿 1.3.10

몇 가지 연구가 끝나면 클래스 경로에 여러 복사본 또는 스트럿 버전이 있으므로이를 제거하고 하나만 유지하십시오. 네가 말했지 만, 내가 찾은 모든 답은 이것을 가리킨다. 그래서 당신은 아마 가지고 있지만 발견하지는 못할 것이다.

또한 병 파일이 이미 포함되어 있으므로 jar 파일을 제거하십시오.

참조하십시오 struts.jar 파일이 와 같은 공통 영역에 보관하지 않아야

는/lib에 있었다. 각 struts 응용 프로그램의 WEB-INF/lib 폴더에 포함되어야합니다.

당신의 전쟁 lib 폴더에서 또는 글로벌 공유지 lib 디렉토리에서 Struts의 핵심 API 항아리를 제거합니다.같은 장소에 2 개의 병이 있습니다. 은 다른 클래스 로더에 의해로드되고 따라서 캐스팅은 입니다.

스트럿츠가 동일한 작업 서블릿 인스턴스에 여러 서블릿 매핑을 지원하지 않습니다 org.apache.struts.action.ActionServlet 클래스를 포함하는 정확한 항아리에 대한
