JSP + Jetty 프로젝트의 Jasper 예외

JSP와 Jetty에서 시작하고 있으며, 프로젝트의 인덱스 페이지를 구성하고 시각화하려고합니다. 내 자바 EE Eclipse 프로젝트에서 부두를 구성한 후, 나는 브라우저를 통해 페이지를 엽니 다 시도하고 다음과 같은 예외가 있어요 :JSP + Jetty 프로젝트의 Jasper 예외

내가 프로젝트를 구성하는 동안 뭔가 잘못 한 느낌이 있습니다. 내가 확인해야 할 정보가 있습니까?

추가 정보 :

부두 버전 : 부두 - 유통 - 9.4.2.v20170220
JDK 버전 : jdk1.8.0_121
이클립스 : Neon2 4.6.2

감사합니다.

바람둥이와 부두가 뒤섞여 있습니다. 부두를 사용할 때

이 클래스 ...

org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

는 ... 존재하지 않을 것이다.

또한 수신중인 오류 메시지는 사용자 환경에 여러 JSP 또는 Jasper 구현이 동시에 존재할 가능성이 큽니다.
