 I created the following test:
 ***
 ?
 class Test
 {
   protected static $_instance = null;
   protected $_variable = null;
   /**
  * Singleton instance
  */
 public static function getInstance()
 {
 $reflection = new ReflectionClass('Test');
 foreach ($reflection-getProperties() as $property) {
 $name = $property-getName();
   echo Member: .$name.BR /
 }
   if (null === self::$_instance) {
 self::$_instance = new self();
 }

 return self::$_instance;
 }
 }
   $testInstance = Test::getInstance();
 ?
 ***
 If I execute the test under regular PHP, the result is:
 ---
 Member: _instance
 Member: _variable
 ---
 If I execute it under Quercus, I just get
 ---
 Member: _variable
 ---
 The strange thing is that accessing the $_instance static memeber in
 this little test works, but a very similar code is inside
 Zend_Controller_Front class in the Zend framework and there it
 complains that $_instance has not been declared, even though you can
 see the declaration a couple of lines above.

 So, even though is seems it is not the full issue, it seems to be
 strongly related. In any case, one would say that reflection in
 Quercus is broken, right?

 Tested using Resin 3.1.7a and resin 3.2.1. Trying to use Zend in 3.2.1
 I don't get the error I was showing above, but a blank page and no
 error message anywhere.

Well, moving forward

I've advanced a bit on the 3.2.1 front as the $_instance not defined  
problem is no longer there, even if reflection is still broken. The  
next issue I found is that accesing a stack, the isset(stack-{$name})  
returns 1 (true) and then stack-{$name} returns false, where isset  
is expected to return false directly as the object is not really  
inside the stack. Not sure how that is supposed to work in PHP, but  
Zend checked with isset() for existance, this failing.

This happens in Zend/Controller/Action/HelperBroker.pjp, line 232

Then I also found out PHP_EOL is not defined, which is not exactly a  
bug, but Zend uses it, so I defined it not to get tons of PHP_EOL  
all around :).

With those changes I was able to render the layout, but not content is  
being displayed and, if I have to believe the traces, neither the  
Controller or the View are being called.

This time I'm getting no error, trace or anything... Aren't  
interpreted languages fun? :)

Hi Adriano,

Thanks for your answer. I'm trying with the latest release of Zend,  
(1.6.2)  fresh from their site.

I follow their quickstart guide, substituting the Apache .htaccess  
file with the URLRewrite filter to redirect all requests to  
WEB-INF/php/public/index.php, storing the Zend framework in  
WEB-INF/php/library/Zend and creating the  
WEB-INF/php/application/bootstrap.php file the instructions mandate.

If using Resin 3.1.5, accessing the application raises a
***
Fatal Error: 'Array' is an unknown function. [spl_autoload_register]
***
but that's a well-know bug of Quercus in 3.1.5, fixed in 3.1.7.

I then try with 3.1.7a and I get these errors:
***
...bootstrap.php:16: Fatal Error: Zend_Controller_Front::$_instance is  
an undeclared static property
An exception occured while bootstrapping the application.
...bootstrap.php:16: Fatal Error: Zend_Controller_Front::$_instance is  
an undeclared static property
Stack Trace:
***

As I used copy/paste and I used the same files in a MAMP environment  
some days ago, I thought it might be a Quercus thing, but I could not  
find anything about it.

I can send you my setup if you wish, but I just followed the steps in  
the quickstart guide, copy/pasting the content of index.php and  
bootstrap.php.

Regarding the simple NuSOAP test, I include the library and try one of  
the samples that issues something like:
***
...
$client = new  
soapclient('http://www.scottnichol.com/samples/hellowsdl3.wsdl',  
true,$proxyhost, $proxyport, $proxyusername, $proxypassword);
...
***
And always in these lines I get Server failed to send headers, even  
though if I try accessing the WSDL files with my browser, I can see  
them normally. The debug trace claims that the answer returned an  
empty answer... but they are answering the browser so...

Thanks for your help,
S!

 Hello Daniel,

 I had success running my project that uses ZF 1.5.2 on top of Quercus,
 as it is using PDO, and the Quercus support at that time (dunno know,
 I'm not watching its progress) didn't implement some necessary things,
 I did implement and so it worked fine.

 Which version of ZF were you using? Share your basic test too, so we
 can try to figure out what is happening.

 Regards,

 Hi,

 I'm doing some experiments with Quercus and one of the things I wanted
 to do is accessing an already existing web service written in Java. I
 also tried implementing the experiments using Zend Framework, even
 though that failed, first with a problem I solved by upgrading to 3.1.7
 and then with more problems I found no information about. I then tried
 to go back to the basics and use NuSoap and all I get when I use it is
 server failed to send headers and from the error trace, it seems it
 never reads any answer from the server ( I tried with public servers
 with WSDLs that work ) but I still have to verify if it is a problem
 with Quercus or my setup. As all I could find is that the simple 3 lines
 I wrote should work and they are quite basic... well, I'll check this
 weekend :).

 In any case, what's the status of Quercus regarding those subjects? Was
 anybody able to run the Zend framework under Quercus? Or develop some
 kind of Web Service client? The information is quite scarce and the
 documentation is not too thorough, specially the list of applications
 supported as the link simply goes to the documentation page ;).

 The forums (http://forum.caucho.com/) are kind of weird... how can one
 see the replies to the topics? Do I have to be registered for that?

 As a newbie in this topic, I have to say the information about the
 subject is spread and difficult to follow. There are different web sites
 with different styles, the wiki, the mailing lists, the forums...
