从Web客户端调用webservice突然失败

Question

我在weblogic中遇到了一个奇怪的问题，我们的web客户端突然无法调用webservice并连续数小时抛出以下异常。在webservice服务器端，未捕获任何异常，但在访问日志中仅找到http 500。重新启动托管webservice的weblogic托管服务器后，问题得到了解决。

web客户端和webservice服务器几个月来一直工作正常，但现在突然出现了问题。我相信这不是应用程序错误，因为问题在重启后得到了解决。

有没有人知道原因或有过类似的经历？

这是一个很老的问题，但是。。。此问题通常与属性反序列化/解析器相关。。。可能您已经编辑了包含错误的行-如下所示：

格式化程序在尝试反序列化消息时引发异常：尝试反序列化参数时出错

当我尝试更新我的类正在调用的WSDL（轴客户端）时，我也会遇到这个错误。

验证是否已将项目库升级到Weblogic版本。
