持续范围失败？

Question

我也照做按规格搜索8.2.2持久单元的范围， 之一，但它引发异常像

15:08:09,956 WARNING [FileZippedJarVisitor] Unable to find file (ignored): file:entities1.jar 
java.io.FileNotFoundException: entities1.jar (The system cannot find the file specified) 
...similarly other one too 

这里失败的原因是耳朵的结构：

|-ear-- 
      |-lib--|... some libs ... 
      |  |--my-persistence-xml.jar 
       |--entities1.jar 
       |--entities2.jar 

      |-ejb-1.jar 
      |-web-1.war 

这里是持久性：

<persistence-unit name="pu" transaction-type="JTA"> 
     <provider>org.hibernate.ejb.HibernatePersistence</provider> 
     <jta-data-source>java:/mypu</jta-data-source> 
     <jar-file>entities1.jar</jar-file> 
     <jar-file>entities2.jar</jar-file> 
     <properties> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/> 
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/> 
      <property name="hibernate.show_sql" value="true"/> 
      <property name="hibernate.format_sql" value="true" /> 
     </properties> 
    </persistence-unit> 

Answer 1

persistence.xml应放置在您的0 META-INF文件夹模块。在这种情况下，您可以使用persistence.xml而不使用<jar-file>。所有实体将自动注册。

如果你想使用<jar-file>那么路径应该是

<jar-file>../../entities1.jar</jar-file> 
<jar-file>../../entities2.jar</jar-file> 

拿什么my-persistence-xml.jar。它是jar或xml？
