我正在尝试使用 Apache Axis2 1.4.1 创建合同优先的 Web 服务。由于 Eclipse 有一个看起来相当完整的 wsdl 编辑器，我开始使用 Eclipse 的编辑器自动处理我的 wsdl。一切都很好，我可以使用 wsdl2java 生成 Java 类，并且 Web 服务在部署时工作。但是，将异常或故障添加到 Web 服务会导致异常指出元素 QName 对于故障为空。有谁知道这可能是什么原因？检查 wsdl 也没有给我任何直接的答案。似乎故障/异常的定义就像其他元素一样。

这是命令和堆栈跟踪：

我想我现在已经自己解决了这个问题。似乎由于某种原因，eclipse WSDL 编辑器没有将错误添加到 WSDL 的绑定部分。

所以当我添加时：

<wsdl:fault name="fault">
  <soap:fault use="literal" name="fault" />
</wsdl:fault>

到绑定，它编译得很好。

完整的 wsdl 现在是：

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/JavaIntegrationModule/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="JavaIntegrationModule" targetNamespace="http://www.example.org/JavaIntegrationModule/">

我也是！您的解决方案节省了我环顾四周的时间:)

顺便说一句，在 Eclipse 中，当您单击 WSDL 查找的设计选项卡并选择绑定元素时，您可以从属性视图中自动“生成绑定内容”。通过这种方式，您不必手动修改 WSDL 源代码。
