使用EJB持久化。 如何在其上配置持久性單元？

Question

我一直在學習J2EE技術​​。 現在，我正在嘗試在EJB中開發CRUD，但是當我嘗試部署Web應用程序時，出現了這些問題。 我對此一無所知。 你能給我一些提示嗎？

這是我實際的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>

這是我嘗試部署應用程序時的WildFly錯誤：

感謝大伙們！

RedFIVE，謝謝您的關注！ 我正在和我的老師談話，他記得我關於NETBeans在Hibernate JPA中遇到的問題。 因此，我嘗試更改EclpiseLink提供程序，並在GlassingFish服務器上運行它。 最終完成了！

再次感謝！
