CLASSPATH="/home/amit/jdk1.6.0_24/lib:."

but it still did not work thanks in advance

Answer 1

You need to have the definition of JAVA_HOME before the defintion of PATH. The expansion needs to take place at definition time, else it looks for the folder named "$JAVA_HOME" which you probably do not have.

Answer 2

echo $java _ home 

is wrong.

• blanks aren't optional

• we are case-sensitive

  echo $JAVA_HOME

is the right way.
