Tomcat 7.0 org.apache.catalina.LifecycleException

Question

우선이 첫 번째 게시물은 여기에 내가 뭔가 잘못 pls 경우. 저에게 친절하게 알려주십시오. 또한 자바로 웹 서비스를 개발하는 첫 번째 방법이기도합니다. 검색 기능을 사용하면서 답변을 찾지 못했기 때문에 아이디어를 요청해야합니다.

어제 저는 Eclipse (EE)에서 동적 웹 프로젝트를 실행하고 있었지만 모든 것이 잘 작동했습니다. 그런 다음 새로운 동적 웹 프로젝트를 만들고 일부 클래스 파일, jar 파일을 복사 한 다음 새 web.xml 파일을 만들었습니다. 그 후 나는 새 프로젝트를 실행할 수 없으며 어제 잘 작동했던 프로젝트를 실행할 수 없습니다. 내 콘솔의 출력은 다음과 같습니다.

web.xml 파일에 서블릿을 추가했습니다.이 서블릿 매핑에 알 수없는 서블릿 이름 CW 서비스를 지정하는 것과 같은 오류 메시지가 표시됩니다. web.xml을보고 서블릿과 서블릿 매핑을 올바르게 만들고 서블릿 섹션의 클래스 이름이 클래스 경로에 있는지 확인하십시오.
