Set environment variable in shell script/access in Java program

Question

I want to set environment using shell scrip in Ubuntu 10.04 and want to access in java program. I have wrote shell script like this:

#! /bin/sh
export JAVA=         


        

Answer 1

How are you sourcing the script?

$./myscript.sh 

or

$source ./myscript.sh 

The second will set the environment variable to current shell. The java program looks ok.

EDIT: based on the comment

It was a problem related to subshell. A quick read is

Answer 2

What are you trying to do exactly?

Running JAVA=/home/ubuntu java SystemEnv works fine (i.e. it outputs "/home/ubuntu")

If you want to export environment variables to the parent process, you have to source it:

source ./myscript.sh
. ./myscript.sh # Alternative form
