Can any one tell me, how to set java home in Ubuntu 12.10?
Open terminal by hitting Ctrl+Alt+T and execute following command:
Now go to end of file and add the following lines:
export JAVA_HOME=/path/to/jdk/folder #usually /usr/java/jdk or /usr/lib/java/jdk export PATH=$PATH:$JAVA_HOME/bin
Now in terminal type:
sudo source ~/.bashrc
This will make it appear on every terminal if open.
Now you can cross check it by typing following line in terminal
It will show you path of your jdk at the end
For more information visit this link
JAVA_HOME=/usr/lib/jvm/java export JAVA_HOME PATH=$PATH:$JAVA_HOME/bin export PATH
This should work, but make sure to change
/usr/lib/jvm/java with your java path.
Well that will be easy, just open terminal and do
For one user
For all users
And just add line like this
export PATH=$PATH:/usr/java/jdk1.5.0_07/bin export PATH=$PATH:/usr/java/jdk1.5.0_07/bin
Just make sure that path is right. And if you did it for all users you will need to activate it using
sudo source /etc/profile
To set JAVA_HOME for all users do as Follows:
sudo gedit /etc/environment JAVA_HOME =":usr/lib/jvm/java-7-openjdk-amd64/bin" CLASSPATH =":usr/lib/jvm/java-7-openjdk-amd64/bin:/home/something etc whatever you want etc"( separated by semicolon )
