We have this scenario.
We have installed JRE 1.6 and the developer issues the command
and he gets java version “1.6 …”
But we have also installed JRE 1.7 and now our developer asks us to replace java 1.6 terminal command with java 1.7.
Let’s see how we can fix this issue in Ubuntu:
Issue the command
sudo update-alternatives --config java
Ubuntu prompts you to select another alternative for
java, and updates the symlink
/etc/alternatives/java to point to the newly selected provider.
So, after selecting java 1.7 from the list, issue again the command
to get java version “1.7.0 ….”
