Jboss 7休眠模块没有找到持久性xml类

我想将我的项目从JSF1.2，Hibernate 3.x，Jboss 4.3迁移到JSF 2.1，Hibernate 4.x和Jboss EAP 6.3。在启动过程中，我得到一个错误，指出 `Jboss 7休眠模块没有找到持久性xml类

我的耳朵结构如下。

MyEAR.ear
MyWAR.war（持久性单元myJPA存在于WEB-INF /类/ META-INF）
MyEJB.jar（持久性单元myJPA存在于META-INF）
LIB/MyJPA.jar（持久性单元myJPA是在META-INF本）
META-INF

我的JBoss部署-structure.xml如下所示。 `

<jboss-deployment-structure> 
    <deployment> 
     <dependencies> 
      <module name="deployment.MyJPA" /> 
     </dependencies> 
     <resources> 
      <resource-root path="MyJPA.jar" /> 
     </resources> 
    </deployment> 
    <sub-deployment name="MyWAR.war"> 
     <dependencies> 
      <module name="deployment.MyEAR.ear.MyEJB.jar" /> 
      <module name="deployment.MyJPA" /> 
     </dependencies> 
    </sub-deployment> 
    <sub-deployment name="MyEJB.jar"> 
     <dependencies> 
      <module name="deployment.MyJPA" /> 
     </dependencies> 
    </sub-deployment> 
    <module name="deployment.MyJPA" > 
     <resources> 
      <resource-root path="lib/MyJPA.jar"/> 
     </resources> 
    </module> 
</jboss-deployment-structure>

` 我是新来的Jboss 7所以请让我知道，如果我的设置不正确。

因此，在深入挖掘并了解迁移之后，事实证明，与jboss捆绑在一起的hibernate无法正确读取我的persistence.xml文件。我的持久性xml有用下面的回车写的类。

<class> 
com.someClass 
</class>

我相信hibernate在类名中包含换行符/回车符，因此没有找到它。它在以前的休眠3中工作正常。虽然我明白我的格式不正确，但我希望hibernate能够修剪和使用类名。无论如何，我的问题已解决，希望有人认为这有帮助。
