Webservice 'Failed to load external entity'

mr.burns

Hi,

I have a Windows 7 Professional 32 Bit, IIS 7.5, PHP 5.3.13, Zend Framework 1.11 and Nav 2009 R2 RTC.
To start learning webservices and Navison I wanted to read the Nav companies using the standard webservice called SystemService.
The WSDL I can acces through a browser (http://navsrv:7049/myNavDB/WS/SystemService).

Then I have follwing PHP code isnide a SoapController.php to read the companies:

public function clientAction() {
			$client = new Zend_Soap_Client('http://navsrv:7049/myNavDB/WS/SystemService');
			
			$result =  $client->Companies();
						
			$companies = $result->return_value;
			echo "Companies:<br>";
			
			if (is_array($companies))
			{
			  foreach($companies as $company)
			  {
				echo "$company<br>";
			  }
			  $cur = $companies[0];
			}
			else
			{
			  echo "$companies<br>";
			  $cur = $companies;
			} 						
		}

But if I start the client-Action in a browser I get following error:

An error occurred
Application error
Exception information:
Message: SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://navsrv:7049/myNavDB/WS/SystemService' : failed to load external entity "http://navsrv:7049/myNavDB/WS/SystemService"

I tried with google, but no success, any Idea what 'failed to load external entity' means and how to solve?

Thanks a lot!

Hi Rahsed,

thanks for reply. I didn't follow this block since Nav 2009 R2 RTC does not have any problem with NTLM Authentication.
As I understand I can use 'normal' php classes from Zend framework to access NAV webservices.
(correct me if I am wrong).

I tested the return value of Zend_SOAP_Client against null, it returned something different from null, that means calling

$client = new Zend_Soap_Client('http://navsrv:7049/myNavDB/WS/SystemService');

seems to work correctly. The problem occurs in following line:

$result =  $client->Companies();

Does anybody know what I am doing wrongly?
Thanks again for help!
