我是使用 Web 服务的新手，我正在尝试使用 ws 客户端插件为第 3 方 Web 服务开发客户端。我尝试了文档中的示例，一切正常，但是当我尝试使用上述 Web 服务时，出现以下异常

我环顾四周，发现在某些情况下添加 xalan-2.7.0.jar 可以解决问题。我试过了，还是不行。
有任何想法吗？
编辑：
我正在使用以下代码：
def wsdlURL = "http://ws.webgains.com/aws.php"
def proxy = webService.getClient(wsdlURL)
def result = proxy.getFullUpdatedEarnings(new GregorianCalendar(),new GregorianCalendar(),1,"a","b")
在 webService.getClient(wsdlURL) 中抛出异常
