我使用Web服务相当新，我正在尝试使用ws客户端插件为第三方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，我得到以下异常

我环顾四周，发现在某些情况下添加xalan-2.7.0.jar解决了这个问题。我试过了，但仍然无法工作。
有什么想法吗？
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")
webService.getClient（wsdlURL）
中抛出异常
