Я создал новое простое веб-приложение, спроектированное с сервером hibernate 5, Tomcat9. при запуске проекта показывается следующая ошибка.
Exception
javax.servlet.ServletException: Servlet execution threw an exception
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53)
Root Cause
java.lang.NoSuchMethodError:
