我们正在将应用程序从Weblogic 10迁移到Weblogic 12。由于某些原因，我们无法连接到外部JMS主题，在开发环境中部署EAR后，我们得到的唯一信息是

ClassCastException: weblogic.jms.client.JMSConnection cannot be cast to weblogic.jms.client.JMSXAConnection
在ACC环境中，我们得到了另一个（但有点类似的例外）

两种环境都运行Weblogic 12.1.3.0.0

在从Weblogic 10（和Java6+OpenJPA1）迁移到Weblogic 12（和Java7+OpenJPA2）之前，同样的配置在Weblogic 10上工作得非常好

我们的MDB现在看起来是这样的（没有注释或任何东西，它只是一个空壳，什么都不做，甚至它也不工作）

####经过一个长周末，MDB自动连接到远程主题。我们仍然不知道为什么Weblogic12认为MDB是事务性的，而Weblogic10没有。这可能是因为远程主题被短暂地配置了XA连接工厂，但我们现在将永远不会看到它。weblogic也可能缓存连接，因此总是返回XA连接，即使我们不需要或不想要。清理所有缓存并重新启动两端可能会解决周末问题（否则等待另一个长周末=）。长周末过后，MDB会自动连接到远程主题。我们仍然不知道为什么Weblogic12认为MDB是事务性的，而Weblogic10没有。这可能是因为远程主题被短暂地配置了XA连接工厂，但我们现在将永远不会看到它。weblogic也可能缓存连接，因此总是返回XA连接，即使我们不需要或不想要。清理所有缓存并重新启动两端可能会解决周末问题（否则等待另一个长周末=）
