Unhappy Help php compile javac or java system environment variable


can anyone tell me how to set the environment variable on linux so that it can just run the java or javac command only!!

=============================
/usr/java/j2sdk1.4.2_04/bin/java HelloWorld
|
V
java HelloWorld
=============================

I have append the line at /etc/profile
#set java environment
export PATH=$PATH:/usr/java/j2sdk1.4.2_04/bin
export JAVA_HOME=/usr/java/j2sdk1.4.2_04
export CLASSPATH=/usr/java/j2sdk1.4.2_04/lib:$CLASSPATH:.





the following code works but I don't understand need to specify the whole path to run java and javac at php

$last = exec("/usr/java/j2sdk1.4.2_04/bin/javac $filename", $output);
$last = exec("/usr/java/j2sdk1.4.2_04/bin/java HelloWorld",$output);




<?php

if(!defined('_DEBUG_')) define('_DEBUG_',1);

if(_DEBUG_)
{
header('Content-type: text/plain');

ini_set('display_errors','1');
error_reporting(E_ALL);
}
$filename = "HelloWorld.java";
$last = exec("/usr/java/j2sdk1.4.2_04/bin/javac $filename", $output);
if(_DEBUG_)
{
echo $last."\n";
print_r($output);
}

$last = exec("/usr/java/j2sdk1.4.2_04/bin/java HelloWorld",$output);
if(_DEBUG_)
{
echo $last."\n";
print_r($output);
}

?>

the PATH depends on which user start httpd ie :
add export PATH=$PATH:/usr/java/j2sdk1.4.2_04/bin to your ~/.bashrc
create a infos.php file, put in it : <?php phpinfo(); ?>, place the file in your site directory

sudo /sbin/apachectl start
With a web browser go to www.yoursite.com/infos.php
and look at the PATH indication, it should have /usr/java/j2sdk1.4.2_04/bin in it
