部署时出错 - 无法构建EntityManagerFactory

之前有关于此问题的帖子，但这并没有解决问题。

当我部署应用程序战争时，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)

不确定如何解决此问题。

的applicationContext.xml

答案 0 :(得分：1)

你好像混合了Toplink和Hibernate。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。
