How to run my own FTP server without root permissions

Hi all,
I need your help with this problem.

I have my own ftp server implemented in java. If I start it as root it is successfully binded to port 21 and everything works. Now I want to run it as non-root user, but for binding to port 21 it needs root rights. How to solve it?

I alrady try xinetd, but it probably has no feature I need (xinetd starts for each request new instance of server whether single-treaded or not, but I need to start one instance of my ftp server which is capable to handle many request at one time itself).

Any ideas are welcomed.
Regards,
Jirka
