我们正在研究网络服务解决方案。webservice API 为我们提供了几个调用，我们可以使用它们从 Client WebService 实现中检索 SOAP 响应。

该实现基于 AXIS 框架。

所有 API 调用都运行良好，除了在我们收到响应时遇到 SAXParseException 之外。

当我们在 SOAP UI 中尝试时，我们会得到这个特定 API 的有效响应。但是当我们在 Java 项目中尝试时，我们得到了这个 SAXParseException。Java 和 SOAP UI 项目都是使用相同的 WSDL 文件创建的

请查看下面的堆栈跟踪，并分享您的拙见，这里可能出了什么问题。

似乎您没有有效的 xml 响应……类似的东西。

<?xml version="1.0"?>
<node1>
 ... bla, bla
</node1>
<node2>
 ... bla, bla
</node2>
<node_x>
 ... bla, bla
</node_x>

反而 ...

<?xml version="1.0"?>
<node1>
  <node2>
   ... bla, bla
  </node2>
  <node_x>
    ... bla, bla
  </node_x>
</node1>

您应该嗅探网络流量以查看原始格式的内容。如果有人手动构建 xml 代码而不是使用众所周知的工具，我通常会收到此错误。
