Question

我正在尝试在jbosss eap 6.3上部署使用eclipse链接配置的应用程序作为jpa提供程序但似乎EclipseLink和jboss之间存在问题，因为我在部署

时遇到堆栈溢出错误

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="classType" id="classType" required>
  <option value="" disabled="true" selected="true">Select Your Class Type</option>
  <option value="Beginner">Beginner</option>
  <option value="Intermediate">Intermediate</option>
  <option value="Advanced">Advanced</option>
</select><br/>

<select name="studentType" id="studentType" required>
  <option value="" disabled="true" selected="true">Select Your Student Type</option>
  <option value="lowerLevel">Lower Level</option>
  <option value="upperLevel">Upper Level</option>
</select><br/>

我是否需要在jboss（standalone.xml）中添加一些配置？

有我的persistence.xml

我的pom.xml（此项目将是另一个项目的依赖项）

        </properties>

    </persistence-unit>
</persistence>

任何建议将不胜感激非常感谢你

感谢 Chris 回答，我设法通过在jboss eap中集成eclipse链接模块来运行jboss eap 6和EclipseLink

我需要创建一个新文件夹：JBOSS_ HOME \ modules \ org \ eclipse \ persistence \ main并在里面复制eclipselink.jar。然后我需要创建关联的module.xml

  <?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.eclipse.persistence">
   <resources>
      <resource-root path="eclipselink.jar" />
   </resources>
   <dependencies>
      <module name="javax.api" />
      <module name="javax.persistence.api" />
      <module name="javax.transaction.api" />
      <module name="javax.validation.api" />
      <module name="javax.xml.bind.api" />
      <module name="org.antlr" />
      <module name="org.apache.commons.collections" />
      <module name="org.dom4j" />
      <module name="org.javassist" />
      <module name="org.jboss.logging" />
   </dependencies>
</module>

完整教程：https://docs.jboss.org/author/display/WFLY8/JPA+Reference+Guide#JPAReferenceGuide-UsingEclipseLink和http://www.eclipse.org/eclipselink/documentation/2.5/solutions/jboss002.htm

此外，despites我的服务器在此之后运行顺利，但在尝试持久保存任何数据后我得到了一个新的错误＆＃34;对象不是已知的实体类型＆＃34;

问题是因为在persistence.xml中我有一行<exclude-unlisted-classes>false</exclude-unlisted-classes>

似乎eclipselink和jboss eap之间存在类加载问题

我需要通过<class>属性

声明明确的实体
