SOAP servers and clients with Zend framework (Getting errors) - zend-framework

Question

I am testing a server and client i made on my webspace.
when i try to call a simple "testServer" function defined in a ServerMap class, I get
"Looks like we got no XML document"
..?
I called getFunctions on the client and testServer is a valid function. I tried catching all exceptions and then calling __getLastResponseHeaders() and __getLastResponse.
header:
string(348) "HTTP/1.1 200 OK
Date: Tue, 23 Jun 2009 19:36:29 GMT
Server: Apache/2.2.11 (Win32) DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.8i PHP/5.2.9
X-Powered-By: PHP/5.2.9
Cache-Control: max-age=1
Expires: Tue, 23 Jun 2009 19:36:30 GMT
Vary: Accept-Encoding
Content-Length: 1574
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html
"
response:
string(1574) "DEBUG HEADER : This is a cached page !
"
If i look at the source html of the response, its actually:
string(1574) "DEBUG HEADER : This is a cached page !<?xml version="1.0"?>
<A lot of xml that looks pretty much like my WSDL file that my Zend_Soap_AutoDiscover generates>
So whats going on? I searched online and i didnt really find any solid solutions.
I don't have blank space before my ..

Answer 1

If you are outputting to the browser, it is hiding the xml cause it is in a . Browsers ignore tags they don't understad.
Do a echo htmlentities($output); to see the xml tags.

Not sure what your problem is, but I can provide a bit of code that I know works for us using Zend Framework 1.8x as a backend SOAP service for silverlight and WCF. This service simples takes 2 integers, adds them and returns the result. Simple as you can get.
Controller Class example:
class SoapController extends Zend_Controller_Action {
/*
* SOAP server action
*/
public function indexAction() {
$request = $this->getRequest();
if ($request->getParam('wsdl') !== null) {
$wsdl = new Zend_Soap_AutoDiscover();
$wsdl->setClass('SoapMath');
$wsdl->handle();
}
else {
$module = $request->getModuleName();
$controller = $request->getControllerName();
$uri = 'http://' . Zend_Registry::get('fullUrl') . '/' . $module . '/' . $controller . '?wsdl';
$server = new Zend_Soap_Server($uri);
$server->setClass('SoapMath');
$server->handle();
}
exit;
}
}
And the actual work is done by 'SoapMath' which is defined as:
class SoapMath {
public function add($a,$b) {
return ($a + $b);
}
}
