Jax-RS (Jersey)가있는 Tomcat7에서 Jibera 5.x, Jpa 2.1, Java EE7 (javaee-api 7.0)을 실행하는 방법

Question

간단한 응용 프로그램을 Java 응용 프로그램으로 성공적으로 실행했습니다. Hibernate 5.x, Jpa 2.1, Java EE7 (javaee-api 7.0) 응용 프로그램에서 사용 된 프레임 워크. 그리고 Jax-Rs 지원을 Tomcat 7에서 실행하고 싶습니다.

ServletContextListener로 응용 프로그램을 시작할 때 오류가 발생했습니다. persistence.jar WEB_INF/lib 폴더가 보이지만 폴더로 보았습니다. beean이 생성되었습니다.

Tomca t 7은 Java EE 7을 지원하지 않으며 WAR에서 이러한 클래스를로드하지 않습니다. Tomcat이 디버그 로그 출력을 내보내도록 재구성하면 그에 따라 WAR에서로드/스킵되지 않는 JAR 파일에 대한 해당 경고가 표시되어야합니다.

당신은 바람둥이 7을 지원합니까 버전으로 종속성을 다운 그레이드하려고 할 수 있습니다, 또는 당신은 버전 8
