EExcelBehaviour Problem

Hi everyone…

I am trying to generate a report… i am trying to use EExcelBehavior extension available in Yii website…

but whenever i run it shows :

Fatal error: Class ‘CException’ not found in C:\wamp\www\yii\framework\YiiBase.php on line 318

I have alredy put the extensions in my project:

/protected/extensions/phpexcel/Classes/PHPExcel.php and

/protected/extensions/eexcelview/EExcelView.php and

/protected/extensions/eexcelview/EExcelBehavior.php

i have created a test controller:

the code is:

<?php

Class TestController extends Controller

{

public function behaviors()


{


    return array(


        'eexcelview'=&gt;array(


            'class'=&gt;'ext.eexcelview.EExcelBehavior',


        ),


    );


}








public function actionTest()


 {


    // Load data (scoped)


    &#036;model = Course::model()-&gt;findAll();





    // Export it


    &#036;this-&gt;toExcel(&#036;model);


   &#036;this-&gt;render('index');


}

}

?>

now when i run:

http://localhost/nielitwebportal/index.php?r=Test/test

It shows

Fatal error: Class ‘CException’ not found in C:\wamp\www\yii\framework\YiiBase.php on line 318

i have searched and tried:

Fatal error: Class ‘CException’ not found in … YiiBase.php

but i could not solve it…

Someone please Help…
