Я использую веб-сервис Rest с реализацией JAX-RS в tomcat 9, установленном локально, с Java 12, установленным в моей системе. Я могу вызвать метод, принимающий запрос POST с полезной нагрузкой JSON. Но не удается вызвать тот же метод с XML полезной нагрузкой.
Нужна помощь для решения этой проблемы.
Ниже приведены подробности моего проекта:
Tomcat version : 9.0.31 (Installed locally)
Java version : 12
