hi forum.
i have recntly been trying to install GroundWork Monitor Open Source 5.1.0 on a Hp Intel machine with 3Ghz procesor and 1Gb ram running fedora 8. Everything seems to be ok but java seems to have a problem whenever i try to install groundwork-foundation it indicates that the JAVA_HOME variable is incorrectly set.
Here is the error::

The JAVA_HOME environment variable is not defined correctly. This environment variable is needed to run this program. NB: JAVA_HOME should point to a JDK not a JRE. error: %pre(groundwork-foundation-pro-2.0.1-48.noarch) scriptlet failed, exit status 1 error: install: %pre scriptlet failed (2), skipping groundwork-foundation-pro-2.0.1-48

I added the following lines to the end of the /etc/profile file

export JAVA_HOME=/usr/java/jdk1.5.0_06

export PATH=$PATH:$JAVA_HOME/bin

i have followed the groundwork manual precisely including the part where you set the JAVA_HOME variable and not sure of what the error means.
Ps. i had a previous newer installation of java(default one in fedora installation) which i just overwrote using rpm -i --force jdk*.rpm, Could this be the cause of the error?

I think the same java home variable error also causes my terminal to display 'bash: ‘export: command not found' twice every time a new terminal screen is started.

Thanks Johannes Truschnigg for the reply but i managed to fix the problem. It seemed like i was the one who defiled a link incorrectly causing a whole lot of issues with groundwork installation.
