我在 Struts2.0.14、Spring 3.0.0M1、Spring Security 3.0.0M2、Eclipselink 1.1.2 中有我的应用程序的工作副本，

现在我正在尝试将其升级到最新版本的框架，所以我放置了 Struts 2.3.4、Spring 3.1.2、Spring security 3.1.1、Eclipselink 2.4.0 jar 文件。

现在，当我运行程序时，它给出了，

java.lang.ClassCastException: org.eclipse.persistence.platform.database.oracle.Oracle11Platform cannot be cast to org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

这是 session.mxl 文件
