Maven 지원을 사용하여 웹 프로젝트를 실행하는 방법

Question

MyEclipse를 사용하여 maven을 지원하는 웹 프로젝트를 만들었습니다. jsp 파일 index.jsp가있어서 프로젝트를 실행하고 싶습니다.이 경우 MyEclipse tomcat 서버를 시작하고이 프로젝트를 실행중인 서버에 배치했습니다.

나는 그것이 나에게 다음과 같은 오류

SEVERE: Servlet.service() for servlet jsp threw exception 
java.lang.NullPointerException

이 내가 받는다는 프로젝트를 만드는 오전과 나는 또한 내 프로젝트에 받는다는을 사용하려면 처음을 제공하는 실행합니다. 모든 종류의 도움이 상당 할 것입니다.

Answer 1

이 나에게 몇 번 일어난

입니다, 제가 생각하는 것은 내 치어이 사건은 MyEclipse에서 이미 웹 컨테이너에 존재하는 일부 라이브러리를 [포함 된 것이 었습니다 Tomcat Server]와 충돌합니다.

이 트릭을 수행하는 방법은 이러한 종속성을 제거하거나 [제공됨]으로 pom에서 표시하는 것입니다. 그러나 그 사실을 정확히 기억하지는 않지만 javax으로 시작하는 거의 모든 것을 기억하고 있습니다.
