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。在启动过程中，我得到一个错误说 `

`

我的EAR结构如下。

MyEAR.ear
MyWAR.war（持久单元myJPA出现在web-inf / classes / meta-inf中）
MyEJB.jar（持久性单位myJPA出现在META-INF中）
lib / MyJPA.jar（持久性单元myJPA出现在META-INF中）
META-INF

我的jboss-deployment-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。

因此经过大量的挖掘并阅读有关迁移的内容后，发现与jboss捆绑在一起的hibernate无法正确读取我的persistence.xml。我的持久性xml使用如下的回车写入类。

f.write(randomDate)

我认为hibernate在类名中包含换行符/回车符，因此找不到它。它在之前的hibernate 3中运行良好。虽然我知道我的格式不正确，但我希望hibernate可以修剪并使用类名。无论如何，我的问题已经解决，希望有人发现这有用。

Jboss 7 hibernate模块没有找到持久性xml类
