我们最近开始遇到与创建基于CXF的SOAP服务相关的错误。有问题的代码部署在临时和生产环境中，每个环境上的2个节点上。在每个环境中，节点是负载平衡的，并且彼此完全独立。该问题仅在登台环境中有效。在上周五问题首次出现前10天进行了升级 生产环境运行相同的代码并正常工作。
以下是产生错误的代码。正如您所看到的，在设置端点或进行调用之前，尝试读取同一战争中打包的WSDL时会出现问题。系统的其余部分，包括其他基于CXF的Web服务，都可以正常工作。
URL wsdl = getClass().getResource("/wsdl/globalplatform/v2.0.0/wsdl/SELifeCycleNotification.wsdl");
SELifeCycleNotificationService service = new SELifeCycleNotificationService(wsdl, new QName("http://globalplatform.org/selifecyclenotification", "SELifeCycleNotificationService"));
堆栈跟踪如下。我们使用带有jboss 5.0.1和JDK 1.6的CXF 2.2.9版。出于显而易见的原因，升级cxf，jboss或jdk不是一种选择。在全局级别更改超时设置似乎也不是一个好选择，因为它可能会影响所有的一切，我不喜欢它。
有人可以指出可能导致此问题的原因吗？由于问题表现在同一环境的booth节点上，很可能是由两个受影响的节点共同的东西引起的，比如网络设置。但是，wsdl读取操作应该是本地的，两台机器都有足够的可用磁盘空间和为JVM分配的RAM，并且系统的其余部分工作正常。
非常感谢任何帮助。
