请问webservice接口的有关问题！各位大侠进来帮忙看看

public String sendCardToGIS(String method,String xmlparam){        String result = "0";        try{            serviceClient = new Service( );            callClient = (Call) serviceClient.createCall( );            //GIS的webservice地址              callClient.setTargetEndpointAddress( new java.net.URL("http://134.224.1.121/JKsite091402/TelAssetWebService.asmx") );            //GIS的webservice方法            callClient.setOperationName(new QName("http://tempuri.org/", method));            callClient.addParameter(new QName("http://tempuri.org/","xmlparam"),org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);               callClient.setUseSOAPAction(true);              callClient.setSOAPActionURI("http://tempuri.org/CardBack");                callClient.setReturnType(org.apache.axis.encoding.XMLType.SOAP_STRING);            String xmlResult  = (String) callClient.invoke(new Object[]{xmlparam});            System.out.println("传的参数为:"+ xmlparam );            System.out.println("返回的结果为：" +xmlResult );                        //解析调用返回的结果XML字符串            TIFResponse tifResponse=IFResponseUtility.buildEntityString( xmlResult );            result=tifResponse.getIfResult( );//这个result是对方返回的xml中的一个节点中的值                        if(!result.equals( "0" ))                {                        result="1";                        if(tifResponse.getIfError( )!=null&&!tifResponse.getIfError( ).equals( "" ))                          logger.error("调用GIS接口时发生错误："+tifResponse.getIfError( ));                        if(tifResponse.getIfErrorStack( )!=null&&!tifResponse.getIfErrorStack( ).equals( "" ))                          logger.error("调用GIS接口时发生错误异常："+tifResponse.getIfErrorStack( ));                                }        }catch ( Exception e ){            System.out.println( "调用失败！" );            e.printStackTrace( );            logger.error( e.getCause( ).getMessage( ));            if( e.getCause( ).getMessage( ).equals("Connection timed out: connect")){                  return "2";            }            return "1";        }            return result;    }
