getting server/script information

We currently hava script that logs infomation when we link to an outside website. It is in php, but I need to convert it to java. Could someone please help me? Below is the PHP code:

function log_and_redirect($where){

global $SCRIPT_FILENAME,

$SERVER_ADDR,

$SERVER_NAME,

$SCRIPT_NAME;

$to=base64_encode($where);

$from=base64_encode("http://$SERVER_NAME$SCRIPT_NAME");

$redirect_string="/redir/?go=$to&from=$from";

return $redirect_string;

}

Thanks!!!
