急问java调用webService问题

Service service = new Service(); 
     Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL("http://10.35.219.253:8081/SHSD.CS/Carinfo")); 
call.setOperationName(new QName("http://10.35.219.253:8081/SHSD.CS/Carinfo","getCarinfoList"));
call.addParameter(starTime, org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
    call.addParameter(endTime, org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
    call.addParameter(maxRows, 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("http://10.35.219.253:8081/SHSD.CS/Carinfo/getCarinfoList"); 
                Object k = (Object)call.invoke(new Object[]{starTime,endTime,maxRows});     
                   return (List)k;
上面是我调用的代码，返回值类型是List但是老报如下异常
