Setting java path in ubuntu

To set the java path in ubuntu you need to edit the profile file

# vi /etc/profile

add these lines into the file

JAVA_HOME=/usr/lib/jdk1.6.0_03
export JAVA_HOME
PATH=${JAVA_HOME}/bin:${PATH}
export PATH

the java_home path should be the path were your jvm is located
usually it will be in the above location.

(this is only one of the several available solution)
