javax.persistence.PersistenceException：無效的persistence.xml

我正在使用Eclipse中的Servlet，JPA，EJB和JBoss進行項目工作。正如你可以在我的專題的標題看，我有一個錯誤在我的persistence.xml文件，但我不知道是哪個：javax.persistence.PersistenceException：無效的persistence.xml

<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>

但是當我嘗試運行我的servlet我有這樣的錯誤：

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.

你的班級路徑上有哪些罐子？ –

請點擊此鏈接http://pbrd.co/17Fdq9P你可以在我的課程路徑中看到jars的screeshoot – Franky

除非你沒有複製粘貼完整的文件，結束標誌丟失。在你的persistence.xml

編輯

看來你的數據源的JNDI名稱錯誤追加

</persistence>

。通常它始於： java:/

這是我的錯，我沒有複製粘貼整個文件。在文件結束標記存在 – Franky

此錯誤表示您正在使用的Hibernate版本在persistence.xml中不支持version="2.1"。將版本更改爲2.0（爲了清楚起見，更新了xsi:schemaLocation）。

這對我工作，謝謝。 – Andy

不要設置一個供應商的價值。

刪除

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

和嘗試。
