我有两个项目“ProjectA.war”和“ProjectB.war”。
在这两个项目中，我都使用 Oracle 11g、JPA2 和 EclipseLink 2.4.2。我正在使用 JBOSS 5.1.0 GA 应用服务器。
两者都有不同的persistence.xml 文件，具有不同的持久性单元名称，不同的数据源文件。在这里，我为两个项目连接相同的 Oracle DB 用户。
我的问题是...首先我在服务器中部署了 ProjectA.war。它工作正常。和数据库操作也可以正常工作。
现在我在 ProjectA.war 之外的服务器中部署 ProjectB.war。因此，当我尝试在 ProjectA.war 上执行数据库操作时，jboss 正在借助 ProjectB 的持久性单元名称在 ProjectB.war 的 persistenece.xml 文件中搜索 POJO 类。但实际上它需要在ProjectA中搜索。
那么，我能做什么？
我的 ProjectA.war 配置如下...

在上面的错误描述中......
"INFO [IportIBEntity] finding IptUsers instance with property: userCode, value: ADMIN"
这里 IportIBEntity 是 ProjectB.war 的持久化单元，但 IptUsers pojo 在 ProjectA.war 中有。因此，它试图在 ProjectB.war 而不是 ProjectA.war 中搜索 pojo
我也闲置了以下链接，但没有进展
请帮我解决问题....
