Dear Sir, My code is :-

For webService:-

import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebService;

@WebService public class PaymentInfo {

@WebMethod
public String updatePaymentDetails(@WebParam String[] parms)
{
    System.out.println("Length of Array = " + parms.length);
        return "abcd";

}

}

and for client is:-

import javax.xml.namespace.QName; import javax.xml.rpc.Call; import javax.xml.rpc.ParameterMode; import javax.xml.rpc.Service; import javax.xml.rpc.ServiceFactory;

public class PaymentInfoTestClient {

public static void main(String[] args) {
    try {
        String NS_XSD = "http://www.w3.org/2001/XMLSchema";
        ServiceFactory factory = ServiceFactory.newInstance();
        Service service = factory.createService(new QName("http://lhcc.rdmindia.com/", "ATOMService"));

        String ENCODING_STYLE_PROPERTY = "javax.xml.rpc.encodingstyle.namespace.uri";
        String URI_ENCODING = "http://schemas.xmlsoap.org/soap/encoding/";

        Call call = service.createCall(new QName("http://lhcc.rdmindia.com/", "ATOMPort"));

        call.setTargetEndpointAddress("http://localhost:8081/lhcc?wsdl");

        call.setOperationName(new QName("http://lhcc.rdmindia.com/","updatePaymentDetails"));

        QName QNAME_TYPE_STRING = new QName(NS_XSD, "string");
        call.setReturnType(QNAME_TYPE_STRING);

        call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
        call.setProperty(Call.SOAPACTION_URI_PROPERTY, "");
        call.setProperty(ENCODING_STYLE_PROPERTY, URI_ENCODING);

        call.setReturnType(QNAME_TYPE_STRING);          

        call.addParameter("arg0", QNAME_TYPE_STRING,ParameterMode.IN);

        String arg0 = new String("123");
        String arg1 = new String("40502820");
        String arg2 = new String("0715");
        String arg3 = new String("21APR2011");
        String arg4 = new String("PNR123");
        String arg5 = new String("500");
        String arg6 = new String("xyz");

        String[] parms = {arg0, arg1, arg2, arg3, arg4,arg5, arg6};

        String result = (String)call.invoke(parms);
        System.out.println(result);


    } catch (Exception e) {
        e.printStackTrace();
    }

}

}
