does anybody connect to dell drac5 from ubuntu firefox?  what's the trick?

http://projects.nuschkys.net/2011/08/11/dell-dracremote-console-discoveries/

the above page suggests that ubuntu's icetea java plugin needs to be
substituted by the sun java plugin.  but i can't find any sun java plugin
in the raring repos.  perhaps i should be looking somewhere else?  or
falling back to an earlier ubuntu?  where/which?
