[PHP+SOAP] Chiamata webservice aspx

[il pupo]

Ciao a tutti,
ho un grosso problema con un webservice (creato in aspx con DB Oracle)
praticamente quando faccio la chiamata (PHP utilizzando la classe nusoap) ottengo come risposta questo errore:
ORA-01008: not all variables bound

posto sia il codice PHP che il WSDL
chiamata PHP
<?
require_once('class/soap.php');
$client = new soapclient('http://XXXXXXXXXX/server.asmx');

$err = $client->getError();
if ($err) {
echo '<p><b>Constructor error: ' . $err . '</b></p>';
}
if ($client->fault) {
echo '<p><b>Fault: ';
print_r($result);
echo '</b></p>';
} else {
$err = $client->getError();
if ($err) {
echo '<p><b>Error: ' . $err . '</b></p>';
} else {

$param = array("dati" => "00000000000");
$result = $client->call(
'setDati',
array("setDati"=>$param),
'uri:setDati',
'http://tempuri.org/setDati'
);

echo "<pre>RESULT: ";
print_r($result);
echo "</pre>";
}
}

?>

Cosa diavolo sbaglio?
Grazie per l'aiuto

l'errore che hai postato è di pl/sql, non sembra relativo all'invocazione tramite php (tranne se non sono stati inseriti correttamente i parametri, ma dal codice che vedo sembra sia ok)

il mio consiglio è quello di testare il webservice con un progetto .net windows forms semplicissimo e controllare che funzioni a dovere.
