SOAP Problems (witout using WSDL) Help Desperately Needed!

[FollowTheCode]

I am doing a project at the minute, requiring me to communicate with a (poorly documented) custom designed server (with 1000's of lines of code in it).  It doesn't make use of WSDL  - however I believe the structure of the SOAP XML Data to be as follows:

 

<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope'>
<SOAP-ENV:Header>
<amsh:username xmlns:amsh='http://ams/header' SOAP-ENV:actor='http://ams/server'>
alex
</amsh:username>
<amsh:password xmlns:amsh='http://ams/header' SOAP-ENV:actor='http://ams/server'>
WIDhBCudeHOI5h0xj8h+J+AVEw0=
</amsh:password>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<EncryptedData>

</EncryptedData>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

 

I am having difficulty constructing a script that creates the above packet.  Forgive me if there any obvious errors, but I am new to PHP, new to SOAP, new to XML, stuck with a server with no documentation and feeling pretty much dumped in at the deep end.

 

I have chosen to use PHP's SOAP extension to do this with, and so far have the following code:

 

<?php 

$server = "http://localhost:8084/AMS-WebModule/AccessServlet";

$SOAPClient = new SoapClient(NULL, array(	"location" 	=> $server,
										"uri"		=> "xmlns:amsh",
										"style"		=> SOAP_RPC,
										"use"		=> SOAP_ENCODED
									));

$auth["username"]="alex";
$auth["hashedpassword"]="WIDhBCudeHOI5h0xj8h+J+AVEw0=";

$SOAPHeader=new SoapHeader('http://ams/header','amsh',$auth); 
$SOAPClient->__setSoapHeaders(array($SOAPHeader)); 

var_dump($SOAPClient);

$XMLPacket ="<EncryptedData>
DiIvrc32LaAYfv9IyG2GuC8/kMq/QTOneS373G4Ubow5g8dlSWcnz0GV5M2
nR3zmKLsl0AFmn2Vy+0DOIEoMLyuaQoi9hOuiBayvxhQaD9NU+35Y15gKjK
yu7IvWyNoyJIxgp69PciMvuAnCAeDnMsol4L/fMyoxBLTTc32VoZ1veKrgm
gj5ew==
</EncryptedData>";

$ReturnedSOAPXMLPacket = $SOAPClient->doRequest($XMLPacket, $server, "", "1.0");

var_dump($ReturnedSOAPXMLPacket);
?>

 

However this results in the following error:

 

Fatal error: Uncaught SoapFault exception: [sOAP-ENV:Client] No Header in C:\WebServer\WebRoot\Projects\ams\index.php:28 Stack trace: #0 [internal function]: SoapClient->__call('doRequest', Array) #1 C:\WebServer\WebRoot\Projects\ams\index.php(28): SoapClient->doRequest('<EncryptedData>...', 'http://localhos...', '', '1.0') #2 {main} thrown in C:\WebServer\WebRoot\Projects\ams\index.php on line 28

 

Any fixes or alternatives are desperately sought in addition anyone who can answer the following q's will be the recipient of much gratitude - I am getting desperate.

Where the XML Namespace is designated as "xmlns:amsh='http://ams/header'" (where ams is the server name) should I be able to view anything at that address (because I can't)?

 

Should there be a Namespace for the <EncryptedData> Tag?

Many Thanks in Advance
