javax.persistence.PersistenceException: Invalid persistence.xml

Question

Я работаю над проектом с помощью Servlet, JPA, EJB и JBoss в eclipse. Как вы можете видеть в названии моей темы у меня есть ошибка в моем файле persistence.xml, но я не знаю, какие:

<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> 
    <persistence-unit name="TrainingAppEJB-PU"> 
     <provider>org.hibernate.ejb.HibernatePersistence</provider> 
     <jta-data-source>java:jboss/datasources/MysqlDS</jta-data-source> 
     <class>fr.entity.Client</class> 
     <class>fr.entity.Course</class> 
     <class>fr.entity.CourseSession</class> 
     <class>fr.entity.Location</class> 

     <properties> 
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/> 
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/gestion_formation"/> 
      <property name="hibernate.default_schema" value="gestion_formation"/> 
      <property name="hibernate.connection.username" value="root"/> 
      <property name="hibernate.connection.password" value="********"/> 
      <property name="hibernate.hbm2ddl.auto" value="update" /> 
      <property name="show_sql" value="true"/> 
     </properties> 
    </persistence-unit> 
</persistence> 

Но когда я пытаюсь запустить мой сервлет У меня есть эта ошибка:

16:59:44,498 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/TrainingAppWeb].[Home]] (http--127.0.0.1-8080-2) "Servlet.service()" pour la servlet Home a généré une exception: javax.ejb.EJBException: javax.persistence.PersistenceException: Invalid persistence.xml.

Как я могу решить эту проблему

Answer 1

Если вы не не копировать-вставить файл полностью закрывающий тег отсутствует. Append

</persistence> 

в вашем persistence.xml

EDIT

кажется, что имя JNDI вашего источника данных неправильно. Обычно он начинается с: java:/

Answer 2

Эта ошибка означает версию Hibernate, который вы используете, не поддерживает version="2.1" в persistence.xml. Измените версию на 2.0 (и уточните для xsi:schemaLocation).

Answer 3

переключатель в

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> 

Answer 4

Не устанавливайте значение поставщика.

удалить

<provider>org.hibernate.ejb.HibernatePersistence</provider> 

и попробовать.
