Glassfish offline updates

Hello,

I need install updates to Glassfish server (Open Source Eition v 3.1.2), which doesn't have internet connection. I found this tutorial http://docs.oracle.com/cd/E18930_01/html/821-2416/gjcya.html#indexterm-583 , but download link to update pakages is broken. I'm wondering if there is some else option to do updates offline?

Thank you for your help

Best regards
