Problem with PEAR::DataObject

[Christian Decker]

Hi,
I'm pretty new to Object Oriented design in PHP (although I'm using PHP
since a long time, and I also code with Java, so this is not a problem
for me) and I need some help with PEAR::DataObject
(http://pear.php.net/package/DB_DataObject).
I tried several times to get it to run but there seem to be some
concepts that I can't get...
I can't even use the Factory to build an object since I get the
following error:

-----ERROR-----
DB_DataObject Error: factory could not find class from Project
----/ERROR-----
Project is a class I wrote (or to be more precise DataObjects_Project).
Ok so here comes my config:

///////////////////////////////////////////////////////////////////////////////
// Setup of DataObject stuff.
$options = &PEAR::getStaticProperty('DB_DataObject','options' );
$options = array(
'database' => $dsn,
'schema_location' => dirname(__FILE__).'/DataObjects',
'class_location' => dirname(__FILE__).'/DataObjects',
'require_prefix' => 'DataObjects/',
'class_prefix' => 'DataObjects_',
);
//
///////////////////////////////////////////////////////////////////////////////
(copied right from the user manual...)
And I have a class DataObjects_Project in
../DataObjects/DataObjects_Project.php:

///////////////////////////////////////////////////////////////////////////////
class DataObjects_Project extends DB_DataObject {
var $project_id;
var $project_description;
var $project_date;
}
///////////////////////////////////////////////////////////////////////////////
As you can see nothing fancy here, but I want to be able to load the
data from the database before expanding the classes...

Can someone help me???
