문제

웹 앱을 quets 웹 서버에 배포 할 때 다음 예외 추적을 얻고 있습니다. 일부 jar 파일이 누락되어 있습니다. 누구든지 뭐가 잘못 됐는지 말해 줄 수 있니?

HTTP 오류 500

/ protuct / prmcounters/default.jsp 액세스. 이유 : 

javax/faces/model/SelectItem
.

해결책

일반적으로 해당 클래스의 여러 버전이있는 경우 응용 프로그램의 클래스가있는 여러 버전의 JAR이 있거나 응용 프로그램 서버가 하나의 버전과 WebApp를 제공하지 않는지 확인하십시오.다른 버전을 포장하고 있습니다.
