This command should tell you what is currently providing the Java virtual machine (java) and the Java compiler (javac):
file /etc/alternatives/java /etc/alternatives/javac
This assumes the "alternatives" system is working properly, which might not be the case, depending on how Java has been "messed up" in the past. To check this, run:
file `which java javac`
If the alternatives system is working correctly and being used by Java, then you should see:
/usr/bin/java: symbolic link to `/etc/alternatives/java' /usr/bin/javac: symbolic link to `/etc/alternatives/javac'
Set up Minecraft server on Ubuntu
First install Oracle Java
Run the following commands in this order to add the PPA, update the source list and then install java:
sudo apt-add-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer
Then run this to check what version you have installed:
java -version
