Hi,

I've been trying to set my PATH and CLASSPATH environment variables so that
they point to my JDK's bin and some Java source files respectively and this
is what I've written in my .profile file:

# PATH should also include the latest jdk "bin" directory
PATH="/usr/lib/jvm/java-6-sun-1.6.0.20/bin:$PATH"

# set the CLASSPATH variable to include anything I do with java
CLASSPATH="/home/jason/code/java:$CLASSPATH"

Yet I don't seem to have much luck, since "echoing" both environment
variables gives me the old value of PATH for PATH and nothing for CLASSPATH:

jason(a)debian:~$ echo $PATH
/usr/lib/eclipse6.0/bin/i386_linux:/home/jason/bin:/usr/local/bin:/usr/bin:/bin:/usr/games
jason(a)debian:~$ echo $CLASSPATH

jason(a)debian:~$

This is strange, especially for PATH, because earlier in my .profile I've
written:

# set PATH so it includes the eclipse bin directory
PATH="/usr/lib/eclipse6.0/bin/i386_linux:$PATH"

And if you notice the output produced by "echo", this directory is well
under the scope of PATH.

What am I doing wrong? Do I need to "export" something?

Thanks.

You did log out and log back in, right? Your ".profile" is only read on
login.

Hrm, your .profile should be "source"d in your current shell, which means
"export"ing it wouldn't be necessary. However, I would suggest "export"ing it
as the first attempt at a work around.

Perhaps the eclipse directory is added to PATH elsewhere (eg, in
..profile in your home directory) or there is a separate "export" line
in /etc/profile.

Certainly.

export PATH=...
export CLASSPATH=...

What happens if you set it in /etc/environment instead? - John
