PHP IDE :: NuSphere Forums :: View topic - Trouble on helloWorld web service using WSDL

Posted: Wed Dec 30, 2009 8:11 am

hello everyone!

i d like to begin with a helloWorld web service using nuSOAP 1.85 library WSDL and php 5.1.4.
i also use the SWSAPI class (webservice.php) as a wrapper class.

When i run the client i get the following message:
Fatal error: Call to a member function on a non-object in C:\Program Files\Computer Solutions\InnoController\www\WebServices\ch5\soap\nusoap\helloWorld_client_wsdl.php on line 11

i wonder if the problem concerns nusoap library and php version.
But i tried with PHP 4 too and i get the same message.
When i debug nusoap.php file, i get a warning like this:
"Assigning the return value of new by reference is deprecated"

Could anyone please help me to find the error?
Thank you!

This is the wrapper class

Code:

<?php
//webservice.php - Wrapper Class

error_reporting(E_ALL ^ E_NOTICE);
define('SOAP_IMP', 'NuSOAP');
if (SOAP_IMP=='NuSOAP'){

require_once('http://localhost:85/WebServices/ch5/soap/nusoap/lib/nusoap.php');
require_once('lib/nusoap.php');
}
else if (SOAP_IMP=='PEAR:SOAP'){
   require_once("SOAP/Client.php");
}
else {
   die ('Constant SOAP_IMP not defined or not recognized');
}

class WebService {
//Service Proxy parses the wsdl and returns a new instance of class
//for that wsdl.

function &ServiceProxy($wsdl_fname)
{
   if (SOAP_IMP=='NuSOAP'){
      $soapclient=new [b]nusoapclient[/b]($wsdl_fname,'wsdl');
      $soap_proxy=$soapclient->getProxy();
      return($soap_proxy);
   }else{
      if (extension_loaded('overload')){
         return new SOAP_Client($wsdl_fname,1);
      }else {
         $wsdl=new SOAP_WSDL($wsdl_fname);
         if ($wsdl->fault){
            echo $wsdl->fault->toString();
            return NULL;
         }
         $class =$wsdl->generateProxyCode();
         eval($class);
         return new $wsdl->service;
      }
   }
}
}
?>

This is the Server impl (nusoap_hello_server.php)

Code:

<?php
require_once('lib/nusoap.php');
$server=new soap_server();
$server->register('helloWorld');
function helloWorld($message)
{
if ($message=='')
{ return new soap_fault('12345', 'client', 'You must supply a valid string');}
else {return "hello $message!";}
}
$server->service($HTTP_RAW_POST_DATA);
exit();
?>

This is the client impl(helloWorld_client_wsdl.php)

Code:

<?php
//include the SWSAPI
require_once('webservice.php');

//Instantiate an object from HelloWorld.wsdl
$HelloService=WebService::ServiceProxy("http://localhost:85/WebServices/ch5/soap/nusoap/HelloWorld.wsdl");

//perform the helloworld operation
$result=$HelloService->helloWorld('World');

print $result;
?>

and the WSDL file..(HelloWorld.wsdl)

Code:

<? xml version="1.0" encoding="UTF-8"?>
<definitions name="HelloWorld"

targetNamespace="http://localhost:85/WebServices/ch5/soap/nusoap/"

<message name="HelloRequest">
<part name="message" type="xsd:string"/>
</message>

<message name="HelloResponse">
<part name="noname" type="xsd:string"/>
</message>

<portType name="HelloWorldPortType">
<operation name="helloWorld">
<input message="typens:HelloRequest"/>
<output message="typens:HelloResponse"/>
</operation>
</portType>

<binding name="HelloWorldBinding" type="typens:HelloWorldPortType">
<soap:binding style="rpc"
transport ="http://schemas.xmlsoap.org/soap/http"/>
<operation name="helloWorld">

<input>
<soap:body

use="encoded"/>
</input>

<output>
<soap:body
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

use="encoded"/>
</output>
</operation>
</binding>

<service name="HelloWorldService">
<documentation>A hello Service</documentation>
<port binding="typens:HelloWorldBinding" name="HelloWorldPort">
<soap:address location="http://localhost:85/WebServices/ch5/soap/nusoap/nusoap_hello_server.php"/>
</port>
</service>
</definitions>
