Arch Linux: Alt+gr not working in Java apps

I got quite confused when my good old trusty Alt+gr key did not work in NetBeans (since I use Norwegian keyboard layout, this key is essential for progamming). The key worked everywhere except in Java apps, actually. Luckily, I figured out how to fix it:

1. Install scim.
2. Add your locale to the scim global config (/etc/scim/global).
3. Start scim from your xinitrc.
4. Restart your X server - it now should work!

For good measure, here's my .xinitrc file:

# SCIM
export XMODIFIERS='@im=SCIM'
export GTK_IM_MODULE="scim"
export XIM_PROGRAM="scim -d"
export QT_IM_MODULE="scim"
scim -d
# OPENBOX
exec openbox-session
