使用EJB进行持久化.如何在其上配置持久化单元

Question

我一直在学习J2EE技术。现在我正在尝试在EJB中推出我的CRUD，但是当我尝试部署我的web应用程序时，我遇到了这些问题。这个我一点头绪都没有。你能给我一些建议吗?

这是我实际的persistence.xml:

    <?xml version="1.0" encoding="UTF-8"?>
<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="UsuarioPU" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>LP3</jta-data-source>
        <class>mack.entities.UsuarioImpl</class>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties>       
            <property name="javax.persistence.jdbc.url" value="jdbc:derby://localhost:1527/LP3"/>       
            <property name="javax.persistence.jdbc.user" value="lp3"/>       
            <property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.ClientDriver"/>       
            <property name="javax.persistence.jdbc.password" value="lp3"/>       
            <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>     
        </properties> 
    </persistence-unit>
</persistence>

当我尝试部署我的应用程序时，这是WildFly错误:

谢谢大家!

RedFIVE，感谢关注!我正在和我的老师谈话，他想起了NETBeans在Hibernate JPA中遇到的问题。所以我试着改变eclipse链接提供商，并在GlassingFish服务器上运行它。终于成功了!

再次感谢!
