[TYPO3-mvc] Problems with class loader

[Andriy Kushnarov]

Dear all,

I'm trying to write a new extension based on extbase from scratch.
I register new plugin, like it was done in blog_example.
"Tx_Extbase_Utility_Plugin::registerPlugin"

But I've got fatal error:
"Class 'Tx_MyPlugin_Controller_ProjectController' not found in
....\t3lib\class.t3lib_div.php on line 4794"
But this controller class presents in the right place.

If I do the same inside blog_example I don't have such problem.
What can it be the problem ?
