00386:     {
00387:         // use include so that the error PHP file may appear

00389:             include(YII_PATH.self::$_coreClasses[$className]);
00390:         else if(isset(self::$classMap[$className]))
00391:             include(self::$classMap[$className]);
00392:         else
00393:         {
00394:             if(strpos($className,'\\')===false)
00395:                 include($className.'.php');
00396:             else  // class name with namespace in PHP 5.3

The file User.php doesn't exists. Are you sure it is the same dir? And is the include path set correct?

Some extra info will make it easier to awnser this question.
