I've installed freemind on ubuntu 12.04. It did not started. I've got a message:
[warning] /usr/bin/freemind: No java runtime was found
Unable to find an appropriate java runtime. See java_wrappers(7)
I checked if I have java. Yes. Oracle 7.
I installed Open JDK 6.
I checked:
sudo update-alternatives --config java
I got:
* 0 /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java 1061 tryb auto
1 /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java 1061 tryb ręczny
2 /usr/lib/jvm/java-7-oracle/jre/bin/java 1 tryb ręczny
Freemind started to work.
