Java 使用动态url的可移植JAXWS客户端web服务出错，仍在搜索本地wsdl

在阅读了这篇文章和其他许多文章之后 我有客户机wsdl，从中我生成了如下java存根：

wsimport.bat   -Xnocompile -keep -Xendorsed  Client_aaa.wsdl

现在，在客户端中，我希望能够设置动态端点URL，在阅读了这里的几篇文章后，我是这样做的：

responseUrl = "...each thread get different endpoint url ...."

    ApiService ApiService = new ApiService();        
    Api port = ApiService.getApiPort();
    int ws_request_timeout = 3000
    int ws_connect_timeout = 3000;
    try{
        ((BindingProvider)port).getRequestContext().put("com.sun.xml.internal.ws.request.timeout",ws_request_timeout);
        ((BindingProvider)port).getRequestContext().put("com.sun.xml.internal.ws.connect.timeout",ws_connect_timeout);
        ((BindingProvider)port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,responseUrl);
    }
    catch(ClassCastException cco)
    {

        cco.printStackTrace();
    }
    catch(UnsupportedOperationException uso)
    {

        uso.printStackTrace();
    }
    catch(Exception e)
    {

        e.printStackTrace();
    }
    PACK PACK = port.sendAPI(MESSAGE);

但当涉及到客户端的实际调用时，我得到了一个例外：

Exception in thread "pool-1-thread-20" javax.xml.ws.WebServiceException: Failed to access th
e WSDL at: file:/D:/Java_2/libs/JAXWS2.2.5-20110729/jaxws-ri/bin/Client_aaa.wsdl.
 It failed with:

如何将其移除？或者更好的方法是，当我尝试使用动态endpoit调用时忽略它

@WebServiceClient(name = "ApiService", targetNamespace = "http://www.endpointurl/NP/2.0/", wsdlLocation = "file:/D:/Java_2/libs/JAXWS2.2.5-20110729/jaxws-ri/bin/Client_aaa.wsdl")
