Question

我在tomcat上使用JAX-WS运行Java Document Literal WebService，网络使用HTTPS。 Java＆amp; .Net WS客户端工作正常，而iOS上的MonoTouch客户端在WebService响应期间抛出异常。我已经检查过请求在服务器上被正确命中但是返回到MonoTouch客户端的响应会在随机WebService响应上抛出以下异常（某些响应成功）：

[System.Xml.XmlException: Document element did not appear.  Line 1, position 1.

在iOS客户端，我们正在监控网络流量并通过对等方获得所有响应的连接重置，即使某些响应正在恢复正常。

任何帮助？

看起来您没有收到有效的XML响应。可能是服务不喜欢您的请求并返回（HTML）错误消息（例如500）。

查看正在发生的事情的简单方法是使用WireShark（或类似的工具来嗅探网络流量）并从iOS模拟器运行应用程序。捕获的数据应显示您的请求和服务器的响应。这将告诉您确定它是否是XML响应，或者如果不是，则会告诉您正在返回的错误消息。
