Integrate CKFinder don't work

Hello,

I try to integrate CKFinder in CKEditor without result.

I have test the CKFinder by using ckfinder.html and it's work good.

I use CKEditor whith this method :

<textarea class="ckeditor">Text</textarea>

And I try to put this code into the config.js :

CKEDITOR.replace( 'editor1',
{
 filebrowserBrowseUrl : '/astumail/public/js/ckfinder/ckfinder.html',
 filebrowserImageBrowseUrl : '/astumail/public/js/ckfinder/ckfinder.html?Type=Images',
 filebrowserFlashBrowseUrl : '/astumail/public/js/ckfinder/ckfinder.html?Type=Flash',
 filebrowserUploadUrl : '/astumail/public/js/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files',
 filebrowserImageUploadUrl : '/astumail/public/js/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images',
 filebrowserFlashUploadUrl : '/astumail/public/js/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash'
});

But the browse button does not appear in CKEditor.

I don't understand what i have forgot ?
