Thread: Web Services Frustration

I am trying to use a web service for the first time via PHP using the Zend_soap_client.

Here is the code I am using:

Code:

    public function talkAction()
    {
        Cds_Log::traceEntry();
        $client = new Zend_Soap_Client("http://serv:10021/web/services/WSV0201?wsdl", array('encoding' => 'UTF-8', 'soap_version' => SOAP_1_1));
        $myFunctions = $client ->getFunctions();

        foreach($myFunctions as $func) {
            Cds_Log::trace("function: " . $func);
        }
        
        $types = $client->getTypes();
        foreach($types as $type) {
            Cds_Log::trace("type: " . $type);
        }
        
        $result = $client->wsv0201(array('param0' => 'prototype')); 
        echo $result->wsv0201Response;
        Cds_Log::traceExit();
    }

I have put some logging into other places of the code and here is what I am seeing:

Code:

I believe I am calling the correct function and passing the parameters correctly but I get the following errors:

Code:

java.lang.RuntimeException: Invocation of program failed.

From what I can tell from the log is the request is not being built correctly. I am not passing the value or prototype for param0. Not sure this should matter though as the param0 is nillable according to the wsdl.

Anybody have any ideas on this?
