Question

我们正在开发Web服务解决方案。 webservice API为我们提供了几个调用，使用它们可以从Client WebService实现中检索SOAP响应。

实施基于AXIS框架。

当我们收到响应时，除了我们面临SAXParseException之外，所有API调用都能正常工作。

当我们尝试使用SOAP UI时，我们会获得针对此特定API的有效响应。但是当我们尝试Java项目时，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

似乎你没有响应的有效xml ......就像那样。

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

而不是......

<?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。如果有人手工构建xml代码而不是使用众所周知的工具，我通常会遇到此错误。

使用AXIS Webservice Framework进行SAXParseException
