Debian Java SDK

[Innoxious <escalante@canada.com>]

In the site below one can find a series of '.deb' files related to java
SDK. I'd like to add that ftp site as one of sites in the 'sources.list'
file, but how do I do that?

ftp://ftp.tux.org/pub/java/debian/dists/potato/non-free/binary-i386?

Thanks in advance
