I have installed redhat 6.6 server version.It default comes with openjdk. I have install java 1.8. So how to update the JAVA_HOME to 1.8 ?

I tried checking .bashrc file in the root folder, there is no JAVA_HOME setting now.

below are the details when i try to use "java -version"

java version "1.6"
OpenJDK Runtime Environment
OpenJDK 64-Bit Server VM (build xxxxxxxxx, mixed mode)

You can edit ~/.profile and use:

Code:

export PATH=/path/to/jdk1.8/bin:$PATH
## If you also want to define a JAVA_HOME add this##
export JAVA_HOME=/path/to/jdk1.8

Do note that it's "~/" (your homedir), not "/" (the root directory). If the file doesn't exist, you can create it, or you can use .bash_profile or .bashrc (whatever file exists).
Also note that you need to logout and login back again for the changes to take effect.
