Jboss 7休眠模块没有找到持久性xml类

Question

我正在尝试将我的项目从 JSF1.2、Hibernate 3.x、Jboss 4.3 迁移到 JSF 2.1、Hibernate 4.x 和 Jboss EAP 6.3。在启动期间，我收到一条错误消息 `

`

我的EAR结构如下。

• MyEAR.ear
• MyWAR.war（持久化单元 myJPA 存在于 web-inf/classes/meta-inf 中）
• MyEJB.jar（持久性单元 myJPA 存在于 META-INF 中）
• lib/MyJPA.jar（持久性单元 myJPA 存在于 META-INF 中）
• 元信息

我的 jboss-deployment-structure.xml 如下。 `

<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 Jboss 7 的新手，所以如果我的设置不正确，请告诉我。

因此，经过大量挖掘和阅读迁移后，事实证明与 jboss 捆绑在一起的 hibernate 无法正确读取我的 persistence.xml。我的持久性 xml 有用回车编写的类，如下所示。

<class>
com.someClass
</class>

我相信休眠在类名中包含换行符/回车符，因此找不到它。它在以前的hibernate 3中运行良好。 虽然我知道我的格式不正确，但我希望 hibernate 修剪并使用类名。无论如何，我的问题已经解决，希望有人觉得这很有帮助。
