Oops, just saw that clicking on the jarfiles gave you a screenful of garbage, sorry about that. Fixed now.
By the way, on Apache servers to which you don't have root access, but are allowed such via .htaccess, you fix this type of problems with the AddType directive. I have several such distributed throughout my site, e.g.:
AddType application/x-x509-ca-cert .cacert AddType application/octet-stream .jar AddType audio/x-ms-wma .wma
