my code is as follows
String URI ="http://tempuri.org/";
String SOACT="http://tempuri.org/hello";
QName qname=new QName(URI,"AddNumbers");
ServiceFactory serviceFactory= ServiceFactory.newInstance();
Service svc=serviceFactory.createService( qname );
Call call=svc.createCall();
call.setTargetEndpointAddress("http://samrat/service/addservice.asmx" );
call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
call.setProperty(Call.SOAPACTION_URI_PROPERTY, SOACT);
String ENCODING_STYLE_PROPERTY = "javax.xml.rpc.encodingstyle.namespace.uri";
call.setProperty(ENCODING_STYLE_PROPERTY ,"");
call.setOperationName( new QName(URI , "hello"));
TypeMappingRegistry dt=(TypeMappingRegistry)svc.getTypeMappingRegistry();
Object inParams [] = new String [] {"win"} ;
Object res = (String)call.invoke(inParams) ; <--here i am getting error
