Hi everyone,

I have added this to my .bash_profile. Whenever I log in and when I type javac I get a error message (java: command not found). Does the order counts?

PATH=$JAVA_HOME/bin:$PATH:$HOME/bin
JAVA_HOME=$JAVA_HOME/usr/local/jdk1.3.1_02

export JAVA_HOME PATH

Thanks
ny

the order does matter - it can't place a value into PATH if there is none (at that point JAVA_HOME isn't a variable)

Put your lines in this order and remove $JAVA_HOME (unless it was equal to something before this (which I doubt)).

JAVA_HOME=/usr/local/jdk1.3.1_02
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin

how about export?
does the order count for that too?

The export order does not matter. Check the man page on ksh and export
