java调用webservice的问题，求指导

JAVA代码如下： String wsdlUrl ="http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl";           Service service = new Service(); 
    String nameSpace = "http://WebXml.com.cn/";
    String resultFlag = null;
    
try{
      Call call = (Call) service.createCall();        call.setTargetEndpointAddress( new java.net.URL(wsdlUrl));        call.setOperationName(new QName(nameSpace,"qqCheckOnline"));
      call.addParameter("qqCode", org.apache.axis.encoding.XMLType.XSD_STRING, 
       javax.xml.rpc.ParameterMode.IN);
      
      call.setUseSOAPAction(true);
      call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
      call.setSOAPActionURI(nameSpace+"qqCheckOnline");
      
      resultFlag = call.invoke(new Object[]{ "77997004" }).toString();       
}catch(Exception e){

}我写个main方法测试之后 所报异常：
