I have encountered a bit of a problem trying to install FreeMind on Linux, and, I am not sure how to do it the right way, because it would seem that I cannot install rpm packages nor do I have the knowledge on replacing the current JDK version with sun java.
jonathan@ubuntu:~$ java -version
java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.3) (6b27-1.12.3-0ubuntu1~12.04.1)
OpenJDK Client VM (build 20.0-b12, mixed mode, sharing)
rpm -ivh freemind*.rpm jcalendar*.rpm jgoodies-forms*.rpm
