axis2 客户端调用，如何去掉自动产生的namespace部分

Question

axis2 调用.net 的webservice 服务端 ，产生的soap 消息如下  
<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><axis2ns1:Import xmlns:axis2ns1="http://my.test.com/"><userName>huayancs</userName><pwd>123456</pwd><businessType>forLease</businessType><xmlContent>asdf</xmlContent></axis2ns1:Import></soapenv:Body></soapenv:Envelope>希望得到的是   
<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><Import xmlns:="http://my.test.com/"><userName>huayancs</userName><pwd>123456</pwd><businessType>forLease</businessType><xmlContent>asdf</xmlContent></Import></soapenv:Body></soapenv:Envelope>如何处理 ？
客户端代码如下:
EndpointReference targetRef = new EndpointReference(url);
OMElement payload = _import("huayancs"); //方法
Options options = new Options();options.setTo(targetRef);
  options.setAction("http://my.test.com");
  options.setSoapVersionURI("1.1");
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setProperty(HTTPConstants.CHUNKED, false);
ServiceClient sender = new ServiceClient();
    
sender.setOptions(options);
OMElement result = sender.sendReceive(payload);String response = result.getFirstElement().getText();
请问该如何做？求解
