我正在尝试使用SAAJ手动处理Web Service请求，但仍然根据Web服务的WSDL架构验证收到的请求。这个特定的WSDL包含多个元素，我使用wsdl4j提取，当我到达尝试创建新的Validator时，我收到一条关于Validator无法解析一个模式内的引用的错误消息另一个中定义的元素：
org.xml.sax.SAXParseException; src-resolve: Cannot resolve the name 'ns0:CustomerNumber' to a(n) 'element declaration' component.
我已经将实际的WSDL和代码编写成了一些小的东西来创建可重现的东西。 “simple.wsdl”也在Soap-UI中正确加载。这是在Windows 7上使用jdk1.7.0_51。
请注意，我注意到此问题的原始WSDL是由TIBCO BusinessWorks生成的，因此我不认为这是无效WSDL的问题。
我在SO上看到过与此类似的其他问题，但提供的解决方案似乎并不完全符合我的情况，所以我想我会再问一次。
有没有人知道发生了什么以及如何让它发挥作用？

答案 0 :(得分：1)
我必须既使用LSResourceResolver，又将名称空间声明从wsdl文档复制到架构元素，以完成此工作。这是代码：
\b这里也回答相同： Java, Validate XML against an embedded schema in WSDL
答案 1 :(得分：0)
我认为SchemaFactory对于如何导致进口感到“愚蠢”。我相信如果你以相反的顺序（最低级别到最高级别）提供模式，那应该有效。在您有更复杂的依赖项（或同一名称空间的多个模式）的情况下，您可能需要实现自定义LSResourceResolver并将其设置在SchemaFactory上。
