我需要构建一个接受 .wsdl 文件作为输入的实用程序。验证文件并在天气文件有效时提供输出（就语义而言）。如果可能的话，我还想在文件中显示错误（如果有的话）。

我知道网上有可用的实用程序，但我无法通过互联网上传传入的 .wsdl 文件（出于安全目的）。因此，我想使用 Java 以编程方式执行此操作。

如果在java中有任何可用的API，请建议我？

另一种方法是使用 SOAPUI 工具 API。请参考以下链接。尝试导入 WSDL 并捕获任何异常以了解 WSDL 是否正确。

WsdlInterface iface = WsdlInterfaceFactory.importWsdl( "WSDl_LOCATION", true )[0];

与 SoapUI 集成
