WSDLException：尝试解析引用的架构时发生错误

Question

我正在尝试使用 windows xp 上的 eclipse Galileo 和 axis 2 1.4 从本地 WSDL 文件生成代理类。我的问题是，由于 WSDL 中导入的架构，我收到错误。令我困扰的行是：

<xsd:import namespace="http://www.w3.org/2005/05/xmlmime" schemaLocation="http://www.w3.org/2005/05/xmlmime"/>

我尝试运行以下命令运行 wsdl2java：

wsdl2java.bat  -uri SOAService.wsdl -o D:\temp p test -d xmlbeans -a -s -ns2p -uw

并且出现以下异常：

Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException

我怀疑这是由于系统代理不允许将 xsd 检索到 wsdl2java 工具。事实上，我可以毫无问题地从浏览器下载文件。

有一个选项可以指定 wsdl2java 的代理，或者有人已经解决了这个问题？ 目前我已经下载了 XSD，将其添加到项目中并更改了 WSDL 以包含相关文件（而不是远程文件），但我宁愿避免这种情况，因为该文件是第三方服务 WSDL 。

预先感谢您的任何提示。

Answer 1

我想我也遇到了同样的问题，下面是我如何使用 java -D 选项解决它，

java -Dhttp.proxySet=true -Dhttp.proxyHost={value} -Dhttp.proxyPort={value} org.apache.axis.wsdl.WSDL2Java {wsdlURL}

看看它是否对您有帮助。问候

Answer 2

根据用户的安装情况，该解决方案可能无法正常工作。解决方案中没有提及 -Dhttp.nonProxyHosts={要排除的主机列表} 选项，如果运行 Web 服务的服务器是本地的，并且引用了托管在您的环境之外的 xml 文件，或者如果您的代理是未设置为响应本地请求。
