JAX-WS wsimport 无法处理内联命名空间？

问题描述

我正在尝试使用 com.sun.xml.ws:jaxws-maven-plugin 从 WSDL 生成 java 类。

我的 WSDL 文件引用了一个外部命名空间文件：

<wsdl:import namespace="http://www.company.com/"
             location="http://ws.company.com/private"/>

由于此 URL 不公开，我已下载该文件并使用 XML 目录指向它：

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
    <uri name="http://ws.company.com/private"
         uri="file:/ws.company.com.private.xml"/>
</catalog>

问题在于这个命名空间文件包含一个内联命名空间定义：

<wsdl:deFinitions name="Authentication" targetNamespace="http://www.company.com/" ...>
    <wsdl:types>
        <xs:schema elementFormDefault="qualified" targetNamespace="http://www.company.com/"
                   xmlns:xs="http://www.w3.org/2001/XMLSchema">
            <!-- By debugging,I found that this import causes the problem -->
            <xs:import namespace="http://schemas.datacontract.org/2004/07/Tdi.Framework.Entity.ErrorResults"/>

            <!-- (etc...) -->
        </xs:schema>
        <xs:schema elementFormDefault="qualified"
                   targetNamespace="http://schemas.datacontract.org/2004/07/Tdi.Framework.Entity.ErrorResults"
                   xmlns:xs="http://www.w3.org/2001/XMLSchema"
                   xmlns:tns="http://schemas.datacontract.org/2004/07/Tdi.Framework.Entity.ErrorResults">
            <!-- Here's where the deFinition is -->
        </xs:schema>
    </wsdl:types>
</wsdl:deFinitions>

当我运行 wsimport 时，出现以下异常：

据我所知：解析器不喜欢 xs:import 标签没有定义 schemaLocation 的事实。我尝试了各种技巧（甚至将定义复制到外部文件），但似乎没有任何效果。谁能解释一下如何让这个工作？
