休眠为JavaEE应用程序中的JPA Provider

如何解决休眠为JavaEE应用程序中的JPA Provider

| 我正在使用Netbeans 7，Glassfish 3.1开发JavaEE6应用程序。 该应用程序运行良好，已在GlassFish上进行了部署。但是问题是，当我在persistence.xml中将Hibernate设置为提供程序时，出现以下异常：

INFO: Instantiated an instance of org.hibernate.validator.engine.resolver.JPATraversableResolver.

这是我的persistence.xml文件：

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<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\">
  <persistence-unit name=\"EntAppEJB-ejbPU\" transaction-type=\"JTA\">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>schema</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
     <properties>
      <property name=\"hibernate.search.default.indexBase\" value=\"/tmp\"/>
    </properties>
  </persistence-unit>
</persistence>

这些是我包含在项目中的jar文件：

hibernate3.jar
hibernate-jpa-2.0-api-1.0.0.Final.jar
antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
slf4j-api-1.6.1
slf4j-simple-1.6.1
hibernate-search-3.4.0.Final.jar
commons-lang-2.4
hibernate-commons-annotations-3.2.0.Final.jar
hibernate-core-3.6.3.Final.jar
lucene-core-3.1.0.jar

我在这里想念什么？任何建议都是最欢迎的。     

解决方法

        您在CLASSPATH中没有DOM4J JAR。检查您部署的软件包，以查看其是否在WAR文件的WEB-INF / lib中。
