Not able to set JAVA_HOME

Question

I have 3 installed versions of java (1.6,1.7,1.8) in my machine. Java alternatives has been configured to Java 1.8. So whenever i type java -version it is picking up from alternatives and showing java 1.8 .

Here now i want to use other version of java (1.6 or 1.7) , for that i have tried updating the .bashrc with other java paths. But still it is showing alternatives version (1.8)

Is there any way to override alternatives java from user level.

Here is a blogpost explaining how to change jdk version in a *nix environment from terminal:

Answer 2

There is no need to change your environment to switch Java version.

You can simply qualify the version you want to use. Alternatively, just make sure the version you want is first on the PATH, not last.

See my old answer for examples. It's for Windows, but it should work similarly for Linux.

Found the fix

I did like below

export PATH:new_java_path:$PATH . Now it started working for the current session.
