Previously I documented how to get Java installed and running under Ubuntu Linux. That seemed to work OK for most Java applications, but the Mozilla plugins didn’t work. Apparently it had something to do with the gcc version that the packages were compiled with.
Luckily there is an alternate repository with java packages that do work with Mozilla. Add this into your
/etc/apt/sources.list as per usual:
deb http://jrfonseca.dyndns.org/debian ./
And then its
apt-get install j2re1.4 to install
