[linux]unable to start MMOUI Minion after installation

[JokeyRhyme]

I'm having trouble getting Minion to run at all. What puzzles me is I've been doing some Android development and all of that (including the emulator) worked perfectly without needing to modify my system's Java settings. I am assuming this means I have Java installed correctly.

I have it installed in /opt/mmoui which is owned by my current user, and I've tried disabling my iptables firewall too but that didn't have any effect.

I installed it using (disabling the splash was the only way to get it to work):
javaws -verbose -Xnosplash minion.jnlp

uname -a

Linux 2.6.32-gentoo-r7 #3
  SMP x86_64 AMD Phenom(tm) 9550 Quad-Core Processor AuthenticAMD GNU/Linux

java -version

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

java -verbose -jar minion.jar
(see attached: mylog.txt)

Any ideas? I just started playing WoW again on a Linux-only machine (Gentoo) so it would be terrific if I could find a working substitute for Curse Client.

UPDATE: I disabled both iptables and ip6tables and Minion runs now.

UPDATE: My iptables firewall was blocking traffic on the localhost interface. I simply added an exception for it (iptables -A INPUT -i lo -j ACCEPT). Minion now launches properly and one of my other programs is popping up now too.
