NuSoap 1.94与PHP 5.2.17进行Soap客户端调用时发生致命错误

Question

I'm getting an error message when making a call to an xBase++ based web server that is acting as a web service (not using WSDL) when trying to make a soapclient call to it using NuSoap 1.94 with PHP 5.2.17. This exact same code works with NuSOAP 1.94 on PHP 4. Any ideas or help would be appreciated!

Note (I had to remove the https:// part of the addresses from the error message below - I was getting an error posting saying I needed 10 reputation to post 2 links or more)

Thanks,

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'xxx.xxx.com:55055' : failed to load external entity "xxx.xxx.com:55055" in /hsphere/local/home/xxx/xxx.com/phpinvent/inc/functions/xmsg.php:34 Stack trace: #0 /hsphere/local/home/xxx/xxx.com/phpinvent/inc/functions/xmsg.php(34): SoapClient->SoapClient(' https://xxx.xxx ...') #1 /hsphere/local/home/xxx/xxx.com/phpinvent/xmsgtest.php(15): XMsg('LOGIN', Array) #2 {main} thrown in /hsphere/local/home/xxx/xxx.com/phpinvent/inc/functions/xmsg.php on line 34

Here's the code of my test page, and the xmsg function:

<?php
ini_set('display_errors', 'On');

error_reporting(E_ERROR | E_WARNING | E_PARSE);

// include configuration
require_once('inc/config.php');
require_once('inc/nusoap/nusoap.php'); // include the NuSOAP classes

$xmsg_param[0][0] = "userid";
$xmsg_param[0][1] = "TEST";
$xmsg_param[1][0] = "password";
$xmsg_param[1][1] = "TEST";

$result = XMsg("LOGIN", $xmsg_param);
echo("<br>resulttxt: ".$result['xmsg_resulttxt']);
echo("<br>Sessionid: ".$result['sessionid']);

?>

This is quite simple. Your web server can't see the location the WSDL is hosted at. Can you hit the location if you copy the WSDL url and paste it into your browser? You should check that the URL you are using is correct, and whether your web server can even see that location. If not you will need to remedy that before it will work.
