php - Creating nusoap object inside Magento Event Listener throws exception -

in magento 1.7.0.2, have created event listener triggers every time application checks final price of product (the final code not trigger on event, testing convenience, trying here).

the event triggers fine , changes price accordingly, when try create nusoap object make non-wsdl calls external webservice, raises warning , not create client object.

the code is:

    $endpoint = 'http://[ip]:155/[client_name]/[client_name].soap2';      try {         $client = new nusoap_client($endpoint);     } catch (exception $e) {         echo $e->getmessage();     } 

and warning raised:

warning: include(nusoap/client.php)  [<a href="function.include">function.include</a>]:  failed open stream: no such file or directory  in  /var/www/clients/client3/magento/lib/varien/autoload.php on line 93 

the same code works fine if executed on magento root directory, able call correct webservice , parse response.

i have included nusoap libraries (v. 0.9.5) in magento root lib directory, , have not required them specifically.

you've identified problem

when attempt instantiate object using nusoap_client class, php can't find class. per standard behavior, calls magento autoloader method, converts class nusoap_client file path nusoap/client.php, , attempts include file. php, per standard include behavior, looks files at

app/code/local/nusoap/client.php app/code/community/nusoap/client.php app/code/core/nusoap/client.php lib/nusoap/client.php path/of/the/calling/script/nusoap/client.php 

you don't have file @ of these locations, php raises warning. manually require nusoap object, placed loader objects @ 1 of above paths, or add custom autoloader handles library location.
