部署时出错 - 无法构建EntityManagerFactory

有关于此问题的上一篇文章，但没有解决问题。部署时出错 - 无法构建EntityManagerFactory

当我部署应用程序的战争，我收到以下错误

Invocation of init method failed; nested exception is javax.persistence. 
PersistenceException: [PersistenceUnit: default] Unable to build EntityManagerFactory 
at oracle.oc4j.admin.internal.DeployerBase.execute(DeployerBase.java:133)

不知道如何解决这个问题。

更新

的persistence.xml

更新2

修改的persistence.xml

你是否按名称'default'定义了任何持久单元？ – Gaurav 2014-12-06 20:46:46

@Gaurav我找不到任何持久单位称为默认。当我部署应用程序时，应用程序服务器要求父应用程序，默认值为下拉选项。这是否会导致任何问题？ – user75ponic 2014-12-07 01:45:06

发布persistence.xml会有点意义不？因为你在那里定义了你的持久化单元，并且人们看不到它（看起来JPA也看不到它） – 2014-12-07 08:07:32

你似乎是混合TopLink和Hibernate的。来自persistent.xml

<properties> 
    <property name="toplink.logging.level" value="FINE"/> 
    <property name="toplink.jdbc.driver" value="oracle.jdbc.OracleDriver"/> 
    <property name="toplink.jdbc.url" value="jdbc:oracle:thin:@serverdb:1521:devp"/> 
    <property name="toplink.jdbc.password" value="scott"/> 
    <property name="toplink.jdbc.user" value="tiger"/> 
</properties>

用hibernate特定属性替换属性。

我在persistent.xml中使用了hibernate属性，但是我仍然收到相同的错误。 – user75ponic 2014-12-07 11:07:18

已修改的persistent.xml作为Update 2添加到我的问题中。谢谢 – user75ponic 2014-12-07 11:09:42

是您使用maven构建的项目吗？如果不是，您可以检查dist/classes文件夹中是否存在persistence.xml。根本原因似乎是persistence.xml不可发现。其他选项是仔细查看生成的日志。这可能会给你一些提示。 – Gaurav 2014-12-07 11:16:14
