我正在开发一个Java应用程序，负责从服务中获取请求中的数据。请求采用xml的形式。我的Java类从xml获取值并将它们存储在数据库中。 Java类还负责将数据记录到简单文本（.txt）文件中。我已经使用String Builder实现了这一点。另一个信息是该类以消息的形式接收请求。我已经使用JMS来实现这一点。
好的，就是说，当我在一个简单的独立weblogic服务器上部署它时，我的班级工作正常，但我也有一个集群环境，我想在其中部署我的应用程序。我的集群环境有两台服务器和一台负载均衡器。当我在集群中部署它时，它会成功部署。但是一旦我运行任何服务消息就开始堆积起来。我已经对此进行了研究，每个wensite都说重启服务器，清除缓存，确保你的数据源名称和jar文件名不相同。我已经完成了所有这些。问题依然存在。这是我添加的一段代码，之后消息堆积起来

在我清除缓存和所有内容之前，我收到了此错误
