我能够使用XSD 1.1作为独立的Java应用程序进行验证。 但是，当我尝试将其与Jersey一起使用并部署为战争
时，我收到错误03-Oct-2016 11:01:19.018 SEVERE [http-nio-8080-exec-4] com.sun.jersey.spi.container.ContainerResponse.mapMappableContainerException The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container
