Zend_Soap_AutoDiscover doesn't generate wsdl file

Question

I have a problem to generate WSDL file from Zend_Soap_AutoDiscover class.
Could someone explain what I'm doing wrong?

In bootstrap.php I have a method:

public function _initWsdl()
{
    require_once("http://localhost:8080/zf_mta/backend.php");
    $autoDiscover = new Zend_Soap_AutoDiscover('Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex');
    $autoDiscover->setClass('Backend');
    $autoDiscover->setUri('http://localhost:8080/zf_mta/backend.php');
    $autoDiscover->handle();

    return $autoDiscover;
}

And here is backend.php class

class Order {

    /** @var string */
    public $productid;
    /** @var string */
    public $customerid;
    /** @var int */
    public $productcnt;

    public function __construct($productid,$customerid,$productcnt) {
        $this->productid  = $productid;
        $this->customerid = $customerid;
        $this->productcnt = $productcnt;
    }
}

class Orders {

    /** @var Order[] */
    public $orders;

}

class Backend {

    /**
     * @param Orders $orders
     * @return string
     */
    public function placeOrders($orders) {
        return print_r($orders,1);
    }


}

I'm getting error:

Check you error log to get the real PHP error and paste it here. — Florent, Sep 07 '12 at 12:38
@Florent If you mean error from SoapFault class, then it doesn't show anything. — user1409508, Sep 07 '12 at 13:32
That's why I told you to look at PHP error log (or apache's one). — Florent, Sep 07 '12 at 13:36
@Florent I looked to PHP error_log. I added errors to my first post — user1409508, Sep 07 '12 at 13:43
Why did you require `http://localhost:8080/zf_mta/backend.php`? — Florent, Sep 07 '12 at 13:45
@Florent I guess I need that to set class for SOAP? backend.php file is not connected with zf_mta. Its just in same folder, so I need to include it somehow. In book was similar example and worked. — user1409508, Sep 07 '12 at 13:59
**Don't include a remote file**. You should specify its path. — Florent, Sep 07 '12 at 14:01
@Florent wow, thanks a lot, it displays xml code, but shouldn't it create wsdl file? I can't find it anywhere. — user1409508, Sep 07 '12 at 14:36

Florent's comment solves the first problem: your PHP configuration is prohibiting the inclusion of files using HTTP. So you'll need to change the require statement to refer to the file's name in the file system.

However, I see several other problems with your code:

You are setting the URI of the generated WSDL to be the URI of the Backend class. This is not going to work, as that file does not contain the necessary code to act as either a SOAP client or a SOAP server.
Zend_Soap_Autodiscover is usually used in a SOAP server to respond to a request from a client for a copy of the WSDL. Therefore, you would normally include that code in a method that is specifically intended to handle that request, not in the application bootstrap.
Disregarding the previous point, I also noticed that you are returning the Zend_Soap_Autodiscover instance at the end of the _initWsdl() function. I'm pretty sure the code calling the _init...() methods disregards any values or objects that are passed back from those methods, so ultimately this code will do nothing.

I think you need to check out some sample code to really understand how to implement a SOAP server using Zend Framework. The following snippet is about the simplest example of using Zend Framework for SOAP services that I could come up with: http://pastebin.com/9mb64LeG Note that it doesn't use the Zend MVC or routing infrastructure, but it might help you get your head around the basic usage of Zend_Soap_Server and Zend_Soap_Autodiscover.

Thanks for you time spending on explanation. It helped me a little. I started study Zend week ago and I think it's too early for Zend's web services. — user1409508, Sep 10 '12 at 16:01
