How to set Java environment path in Ubuntu

Question

I just installed JDK in Ubuntu with sudo apt-get install openjdk-6-jdk command, after the installation where's the Java bin directory located? And how can I set the environment path for that directory? I have little experience with Ubuntu, can anyone give some advice or suggest any good website for reference?

Answer 1

set environment variables as follows

Edit the system Path file /etc/profile

sudo gedit /etc/profile 

Add following lines in end

JAVA_HOME=/usr/lib/jvm/jdk1.7.0 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin export JAVA_HOME export JRE_HOME export PATH 

Then Log out and Log in ubuntu for setting up the paths...
