My First Shipment Plugin

Hello,
i'm trying to create my first shipment plugin... i don't have problem on the backend (admin).. but at the moment i'm totally confuse about the front end...

i'm adding this code:
class plgHikaShopshippingJNE extends hikashopShippingPlugin {
var $multiple = true;
var $name = 'jne';

//GET CONFIG
function onShippingDisplay(&$order,&$methods,&$usable_methods,&$messages){
var_dump($order);
die();
}
}

but the die isn't triggered as it never called... how to debug it ?

For Manual Payment, Why there is a copy of manual shipment plugin in administrator\components\com_hikashop\plg_hikashopshipping_manual\manual.php ... are they included in the system ?

Hi,

Have you put the files in a zip archive, then install it thanks to the joomla extension system and published it ?
