problem when creating proxyobject using getProxy() with nusoap

when i am trying to use getProxy() method to create a proxy object as given ,

$objClient= new soapclient2($wsdl,'wsdl');
$proxy  = $objClient->getProxy();

the page result is showing the following warning and error.


Warning:  SoapClient::__construct() [function.--construct]: I/O warning : failed to load external entity "" in /home/arun/public_html/globees_webservice/lib/nusoap.php(7006) : eval()'d code
 on line 1

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR:
