Setting java path variable on Fedora Core 4
|
|
|
|
Hi all,
I need help for setting path variable for my Fedora Core 4. I just
installed java sdk 1.5.0_06 and followed the directions below.
It worked perfectly fine until I closed the terminal and re-opened
one. Then, i had to set up the path again to have my shell to find
javac
command.
I suspect that it's because i don't understand "Add to
$HOME/.bash_profile (below)". I would really appreciate it if anyone
help me out.
Thank you.
-----------------------------------------------
Set environment variables. (Add to $HOME/.bash_profile)
PATH=3D/usr/java/j2sdk1.4.0_03/bin:$PATH:$HOME/bin:./
export PATH
export JAVA_HOME=3D/usr/java/j2sdk1.4.0_03
export
CLASSPATH=3D/usr/java/j2sdk1.4.0_03/lib/tools.jar:/usr/java/j2sdk1.4.0_03/j=
re=AD/lib/rt.jar:./

You do exactly what it says. You open the file $HOME/.bash_profile (the file
called .bash_profile in your home directory) in a text editor and add the above
lines to that file. Note that the directory (/usr/java/j2sdk1.4.0_03) will not
be the same on your system, you'll need to replace that with the actual
directory where Java is installed. Forget the CLASSPATH setting, you don't need
(or want) that, it will only get in the way. .bash_profile is only run when you
login, so to get it to execute you need to log out and back in again. You can
execute it without the logout/login by running the command '. ~/.bash_profile'
without the '', but otherwise exactly as written, including all the periods.
Alternatively, you could create a file called /etc/profile.d/java.sh and put the
commands in there so that all users will get the Java environment setup. Set
the permission on /etc/profile.d/java.sh so that all users can execute the file
by running the command 'chmod 755 /etc/profile.d/java.sh'.
