Axis2 SocketTimeoutException:读取超时

Question

我正在尝试构建SOAP客户端来访问国家气象局NDFD SOAP服务。我使用的是使用wsdl2java生成的代码的Axis2 1.6.2。

每次我尝试检索数据时，都会收到一个AxisFault，告诉我Read timed out。我尝试将超时时间增加到500秒，但这只会使它等待更长时间，然后才会给出相同的错误。

错误似乎与这里的错误相同：Exception in thread "main" org.apache.axis2.AxisFault: Read timed out。然而，我不太理解对这个问题的任何回答。

最后一点注意事项。为了避免出现"411错误:需要长度“，我不得不关闭分块选项。我不确定这是否相关。

有没有人知道问题出在哪里？

我在一个项目中遇到了这个错误，根本原因是代理服务器设置。我不得不修改代理，以允许与我试图访问的服务进行通信。我的代码是作为使用自己的代理的自定义应用程序的一部分运行的。因此，这也可能是值得尝试的东西。
