I'm hidden behind a firewall. I do use proxy to get to the internet. Therefore I do have to setup proxy in application server sometimes (when I use the appserv) - either glassfish or Sun Application Server.
It's easy to set it up but I often forgot the parameters. It's worth to save it into this blog entry.
You have to set up following parameters in Application Server
node, tab JVM Settings | JVM Options
I prepared a short flash demo for those that would like to see where to set it up
