[TYPO3-mvc] Extbase - external Class - autoloader

[S.Korth]

Hey all,

i build my first extbase extension. Now i try to include an external 
class. At first i used the normal include, but as i read about the 
autoloader i tried that:


// Generates the needed ext_autoload.php file
$extutil = new Tx_Extbase_Utility_Extension;
$extutil->createAutoloadRegistryForExtension($_EXTKEY, 
t3lib_extMgm::extPath($_EXTKEY));


So far so good. I get my autoload file and it works on my local mamp 
installation. All Classes get loaded.

Now i export the extension and test it on my server.

But, on my server this doesn't work. It doesn't load the external class.
I checked all my configurations, pathes. It's the same typo3, extbase 
version.

php error -> Fatal error: Class 'myclass' not found in /folder.....


What could that be ?


Typo3 4.3.3
Extbase 1.0.2


Thanks so far,
Sascha
