Java - Hadoop

Hello,
I installed Java Sun 6 for Hadoop file system but everytime I try to set it as Java Home, it gets back to be not set as soon as I close the terminal.
Can anyone tell me what to do ?

I used the commands :
sudo apt-get install sun-java6-jdk
sudo update-java-alternatives -s java-6-sun
export JAVA_HOME=/usr/lib/jvm/java-1.6.0_24
echo $JAVA_HOME

Thanks in advance.

any help ?

Based on a tip I found here: http://ubuntuforums.org/archive/inde...t-1010605.html (near the end of the thread), I installed the following in /etc/profile.d/set_java_home.sh:

Code:

---

export JAVA_HOME=$(dirname $(dirname $(readlink -e /usr/bin/java)))

---

Not sure this is the best way, but it so far seems the most automatic way. Before I did this, the static entry I had there became outdated every time Java was updated.

Anyway, hopefully someone will find this helpful.

Indeed, this link has the solution!
