Вопрос:

Я пытаюсь создать простое приложение с гибернацией. Я создал hibernate.cfg.xml и файл сопоставления Personne.hbm.xml . Как только я его запускаю, я получаю исключение: org.xml.sax.SAXParseException

Подробнее: ошибка, которую я получаю, заключается в следующем:

Ответ №1:

Пожалуйста, замените properties на property here

 <properties name="nom" column="nom_personne" />

необходимо изменить на

 <property name="nom" column="nom_personne" />

1. я получаю следующую ошибку: javax.naming. Исключение NoInitialContextException: необходимо указать имя класса в свойстве среды или системы..

2. @MarwenBta Пожалуйста, удалите name="java:hibernate/SessionFactory" и ваши ответы-вопросы.
