I have the following on my .bashrc:

JAVA_HOME="/usr/bin/java"
GRAILS_HOME="/root/grails"
PATH=$PATH:$JAVA_HOME:$GRAILS_HOME/bin

export JAVA_HOME
export GRAILS_HOME
export PATH

However, when I execute > grails in the terminal, I get:

root@localhost:~# grails
grails: JAVA_HOME is not a directory: /usr/bin/java

when I tried to replace to

JAVA_HOME="/usr/share/java"

then the outcome is:

root@localhost:~# grails
grails: JAVA_HOME is not defined correctly; can not execute: /usr/share/java/bin/java

what am I missing in there?

    I would expect JAVA_HOME to contain the bin directory containing java (and others).

    So clearly those two options you’ve selected are not correct.

    Looking at my Ubuntu installation, I have numerous Java packages under /usr/lib/jvm, and I would select an appropriate one there e.g.

    export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64
