我正在为Wildfly 9开发Java Web应用程序。
我写了这个persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence 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"
version="2.1">
<persistence-unit name="Win-Data-PU" transaction-type="JTA">
<properties>
<property name = "hibernate.show_sql" value = "true" />
<property name="jboss.as.jpa.managed" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
<property name="hibernate.connection.provider_class" value="com.klopotek.core.connection.MyHibernateConnectionProvider" />
<property name="jboss.entity.manager.factory.jndi.name" value="java:comp/persistence/Api" />
</properties>
</persistence-unit>
<persistence-unit name="Dynamic-PU" transaction-type="RESOURCE_LOCAL">
<properties>
<property name="hibernate.show_sql" value = "true" />
<property name="jboss.as.jpa.managed" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
<property name="hibernate.connection.provider_class" value="com.klopotek.win.core.connection.DynamicConnectionProvider" />
</properties>
</persistence-unit>
</persistence>
如您所见，我为两个持久性单元定义了一个新的Hibernate连接提供程序。
现在我正在尝试为第二个PU实例化一个新的EntityManagerFactory：
EntityManagerFactory emf = Persistence.createEntityManagerFactory("Dynamic-PU");
但是我得到了这个例外

似乎在EMF创建的内部过程中，Java发现this类不会扩展this
但是，如果您在声明中看到，SchemaDVFactoryImpl实现了SchemaDVFactory。

您认为您认为发生了什么？
答案 0 :(得分：0)
JBoss / Wildfly包含自己的 Xerces / Xalan 版本，然后您必须从部署中排除或使用jboss-deployment-structure.xml排除Wildfly模块。
