axis调用webservice报错

Question

源代码：
 String endpoint = "http://sdkhttp.eucp.b2m.cn:80/sdk/SDKService";        // 创建 Service实例
        Service service = new Service();
        
        // 通过Service实例创建Call的实例
        Call call = (Call) service.createCall();
        
        // 将Web Service的服务路径加入到call实例之中.
        call.setTargetEndpointAddress(new URL(endpoint));// 为Call设置服务的位置
        
        // 调用Web Service的方法
        call.setOperationName(new QName("sendSMS"));
        call.addParameter("softwareSerialNo", XMLType.XSD_STRING, ParameterMode.IN);
        call.addParameter("key", XMLType.XSD_STRING, ParameterMode.IN);
        call.addParameter("mobiles", XMLType.SOAP_ARRAY, ParameterMode.IN);
        call.addParameter("smsContent", XMLType.XSD_STRING, ParameterMode.IN);
        
        call.setReturnType(XMLType.XSD_STRING);  
        
        // 调用Web Service,传入参数
        String retval = (String) call.invoke(new Object[] { "3SDK-EHF-","4545", new String[]{"13567191020"}, "javaWebserviceTest【erp_jwang】" });
        
        System.out.println(retval);
