After some reading its the IBM java and kernel version. I still need help

if you have java install when you type java in a console you get a message with options if you haven't got it you get an error mesage.

since then I have installed the developers kit and it still doesn't work. used the RPM for the sun java.

When trying java -version it get an error message. What gives.

you have to add the the dir in your PATH. Open .bashrc file in you home and add something like this: export PATH=$PATH:/dir/of/java/bin

This is in my /etc/profile
# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|$1($|" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}

# Path manipulation
if [ `id -u` = 0 ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi

pathmunge /usr/X11R6/bin after

unset pathmunge

# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
export JAVA_HOME=/opt/IBMJava2-141
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin



HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
INPUTRC=/etc/inputrc
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi
done

unset i


I just noticed that there is no /opt/IBM dir what should I do
