I am using Linux Mint Cinnamon 14. I have set the $JAVA_HOME
and $PATH
environment variables in ~/.profile
as follows:
export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35 export PATH=/home/aqeel/development/jdk/jdk1.6.0_35/bin:$PATH
I then did source ~/.profile
to make the proper changes.
When I execute java -version
command to check the active java version, it shows the default (already installed open-jdk) java version. How can I override the default open-jdk with the one I downloaded?
UPDATE:
which java
says /usr/bin/java
$JAVA_HOME/bin/java -version
says ‘Permission Denied’
sudo $JAVA_HOME/bin/java -version
(asks for password, then) says Command not found
but cd $JAVA_HOME/bin
, and ls
shows that it is right directory.

While it looks like your setup is correct, there are a few things to check:
- The output of
env
– specificallyPATH
. command -v java
tells you what?- Is there a
java
executable in$JAVA_HOMEbin
and does it have the execute bit set? If notchmod a+x java
it.
I trust you have source
‘d your .profile
after adding/changing the JAVA_HOME
and PATH
?
Also, you can help yourself in future maintenance of your JDK installation by writing this instead:
export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35 export PATH=$JAVA_HOME/bin:$PATH
Then you only need to update one env variable when you setup the JDK installation.
Finally, you may need to run hash -r
to clear the Bash program cache. Other shells may need a similar command.
