java games download PHP programming ?

Hi fellows !
I'm not english so i'm going to try to explain myself the best I can.
In order to program an application for java game download, i'm trying to force download so the user won't be able to download the game if he got the link ( i putted an .htaccess in game folder ).
Here is the link from the page that lists the games :

<a href="force.php?jadpath=$file[url]">mario</a>

here is force.php download script :

if (isset($_REQUEST['jarpath'])){
$file=fopen($_REQUEST['jarpath'],"rb");
header("Content-Type: application/java-archive");
header("Content-Disposition: filename=".basename($_REQUEST['jarpath']));
fpassthru($file);
}elseif(isset($_REQUEST['jadpath'])) {
$myfile=fopen($_REQUEST['jadpath'],"rb");
header("Content-Type: text/vnd.sun.j2me.app-descriptor");
header("Content-Disposition: filename=".basename($_REQUEST['jadpath']));
fpassthru($myfile);
}

here is a sample of the mario.jad file :

MIDlet-Jar-URL: ../force.php?jarpath=uploads/mario.jar

but it do not work. Have you got an idea ?

Append in your httpd.conf file follow lines:

AddType text/vnd.sun.j2me.app-descriptor .jad
AddType application/java-archive .jar

From php code, use only :
header("Content-Type: text/vnd.sun.j2me.app-descriptor");
header("Content-Disposition: filename=".basename($_REQUEST['jadpath']));

In midlet jar file, use :
MIDlet-Jar-URL: path_to_jar_file/mario.jar
