Nusoap- object reference not set to an instance of an object

[Benmcfc]

Hi all,

 

First off, apologies if this is in the wrong section of the forums.

 

I know there's a lot of results in Google for this but I've been unable to fix it.

 

try {
//vars
$userName = "someusername";  
$password = "somepw";

$request = array(
				 'UserName' => $userName,
				 'Password' => $password,
				 'Transaction' => array(
									 'ID' => '001',
									 'TransID' => '000001',
									 'Reference' => 'some_string_0101',
									 'SchemeCode' => 'abc',
									 'ClientReference' => 'some_string',
									 'Branch' => 'some_string',
									 'SchemeBrokerNo' => '42',
									 'SaveState' => 'Pending',
									 ),
				'SaveState' => 'Pending'
				 );

//soap
include 'lib/nusoap.php';
$namespace = "XMLTransferServiceProxy";
$soapACTION = "path/to/action/url"; 
    $URL = "path/to/xmltransferengine.asmx";

$client = new SoapClient($URL);
$client->useHTTPPersistentConnection();
    
    $SaveTransaction = $client -> call("SaveTransaction", $request, $namespace, $soapACTION);

} catch(SoapFault $fault){
echo "SoapFault: ".$fault;
}

print_r($client);

 

This is the soap request:

POST /services/xmltransferengine.asmx HTTP/1.1
Host: host
User-Agent: NuSOAP/0.7.3 (1.114)
Connection: close
Content-Type: text/xml; charset=UTF-8

	</Transaction>
	<SaveState xsi:type="xsd:string">Pending</SaveState>
	</ns8502:SaveTransaction>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

 

This is the soap response from the server:

<detail />      
</soap:Fault>  
</soap:Body> 
</soap:Envelope>

 

As I said, I've visited a number of the results Google brought up for the error code, but have been unable to find the cause of the problem and fix it. Any help would be much appreciated.

Anyone?

I'm seeing this now... did you ever find a solution?

 

Thanks,

The error messages is being gererated by the SOAP server you're connecting to. Either your request is incorrectly formatted / missing bits or there is a fault with the SOAP server you are connecting to.

[bholub]

that's what i was afraid of, i'm trying to work off of just the WSDL file.... in this case that may not be enough.

 

 

thanks

[soak]

The WSDL should be enough to generate a valid request. That's pretty much what it's for, to define a valid request.

 

Might be worth adding every field in the wsdl to your request, seeing if it works then if so, working back from there.

[bholub]

yep, i thought i could leave out fields that had "minOccurs" = 0... but turns out that's not the case. once i add all the fields it works. my b thanks a lot for the help
