<wsdl:service name="KKWSEngIfService">
<wsdl:port binding="impl:KKWebServiceEngSoapBinding" name="KKWebServiceEng">
<wsdlsoap:address location="http://www.konakart.com/konakart/services/KKWebServiceEng"/>

<wsdl:service name="KKWSEngIfService">
<wsdl:port binding="impl:KKWebServiceEngSoapBinding" name="KKWebServiceEng">
<wsdlsoap:address location="http://localhost:8780/konakart/services/KKWebServiceEng"/>
