任务： 我正在使用 WAS 运行时在企业环境中开发 J2EE 应用程序。我必须使用组织已经开发的 JAX-WS Web 服务，并且我只提供了一个 wsdl 来继续。所以为了测试我创建了一个项目的服务；将 wsdl 复制到其中，然后生成客户端。然后我的项目中填充了一堆 java 类。我成功地测试了服务，编写了一个主类并调用了服务端点。
问题： 现在，当我尝试通过将可从 Ivy 存储库中获得的 webservice jar 包含到类路径中来在我已经存在的 web 项目中调用此 web 服务时，我无法运行相同的服务，而是得到一个例外：
javax.xml.ws.WebServiceException: javax.wsdl.WSDLException: WSDLException
(at /definitions/message[1]/part): faultCode=UNBOUND_PREFIX: Unable to
determine namespace of 'tns:getUserResponse'
调试后，我发现错误发生在我使用 URL 和 QName 创建服务实例的位置：
Service#create(URL wsdlDocumentLocation, QName serviceName)
它被捕获到 WebServiceException 类中。
研究：
我曾尝试搜索类似的错误消息，但只找到了我不完全理解的评论：
This problem occurs when the thrown exception is in a different package from the service interface, and the exception is not in java.lang.* or in javax.*. When all of these apply, the WSDL generated by Axis2 1.2 refers to an undefined namespace prefix.
我正在寻找“去过那里”那种有经验的人的回复。我知道这个问题可能过于本地化。
PS： wsdl没有错；组织中的其他应用程序正在使用它。
全栈跟踪：
