Console Command For Rbac

I am trying to create a new command for yiic shell.

I have create a new class named "RbacCommand".

It extends CConsoleCommand.

It overrides the run() function.

When i run the help of yiic shell, it recognizes the new command (rbac).

When i try to run it, this message appears:

exception ‘CException’ with message ‘Property “RbacCommand.” is not defined.’ in c:\xampp\htdocs\yii\framework\base\CComponent.php:174

I’ve tried to put my class script (RbacCommad.php) to files

protected\commands or

protected\commands\shell

Also, i’ve tried to configure the main.php and console.php

with

‘authManager’=>array(

		'class'=>'CDbAuthManager',


		'connectionID'=>'db',


		'itemTable'=>'authitem',


		'itemChildTable'=>'authitemchild',


		'assignmentTable'=>'authassignment',


	),

and

‘commandMap’=>array(

	'rbac'=>array(


		'class'=>'Rbac'


	),


)

i’ve put authManager inside componets.

Always the same message. Any thoughts? Thank you.
