PHP - create and call SOAP web service - error

Every time i try to make a call to my webservice, through the wsdl, i get the error message shown here. I think its probably an issue within the the WSDL defintion, because I am not really sure what i am doing within the WSDL definition to begin with:

 [22-Sep-2011 18:54:46] PHP Fatal error:  Uncaught SoapFault exception:
 [HTTP] Not Found in /www/zendserver/htdocs/dev/csc/request.php:4
 Stack trace:
 #0 [internal function]: SoapClient->__doRequest('<?xml version="...',
 'http://192.168....', 'http://www.exam...', 1, 0)
 #1 [internal function]: SoapClient->__call('EchoText', Array)
 #2 /www/zendserver/htdocs/dev/csc/request.php(4):
 SoapClient->EchoText('test')
 #3 {main}   thrown in /www/zendserver/htdocs/dev/csc/request.php on
 line 4

I have a very simple web service, located at: http://192.168.1.2:10088/csc/csc.php

<?php

function EchoText($text){
    return "ECHO: ".$text;
}

$server = new SoapServer(null,
                         array('uri' => "http://192.168.1.2:10088/csc/csc.php"));
$server->addFunction('EchoText');
$server->handle();

?>

I have an interfacing page, which is what i access and then get the error shown above, located at: http://192.168.1.2:10088/csc/request.php

<?php
$client = new SoapClient("http://192.168.1.2:10088/csc/NewWSDLFile.wsdl");

$result = $client->EchoText("test");
echo $result;
>?

I have my WSDL, located at: http://192.168.1.2:10088/csc/NewWSDLFile.wsdl

UPDATE..
