Custom upload folder - J2EE

Hello, I have integrated CKeditor and CKFinder directly into our J2EE Webapp (running tomcat) . I would like to configure CKFinder so I make uploads directly into a specified directory of the server. (Not only into the Webapp Structure)

Here is my current configuration

Location of Ckeditor /path.to/Webapp/ckeditor

Location of CkFinder /path.to/Webapp/ckfinder

Location of uploads : /path.to/Webapp/images/ckeditor/images

I would like to change this last setting to /path.to/UploadRepository/

Is there something that I miss into the config.js or somewhere else ?

Please find my config.js

CKFinder.customConfig = function( config )
{
    // Define changes to default configuration here.
    // For the list of available options, check:
    // http://docs.cksource.com/ckfinder_2.x_api/symbols/CKFinder.config.html

    // Sample configuration options:
    config.uiColor = '#000000';
    config.language = 'fr';
    //config.removePlugins = 'basket';
    config.height = '800px';
    config.rememberLastFolder = false;
    config.logStackTrace = true;
};

Thanks for your help .

Best

Sebastien
