Hi Daniel,
Is the java executable in your path or the JAVA_HOME environment
variable set? You will need to have the java executable in your path in
order to start rhdb-explain. Since different user can have different JRE
installed on their machine, their java executable may be at different
location, the user need to specify where the java executable is.
You'll also need to make sure that your PostgreSQL JDBC driver
is in the proper location, for more information, pleaser refer to:
http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/guitools/x100.html#AEN179
Hope this helps.
Cheers,
Permaine

You should always have your environment variable JAVA_HOME pointing to your Java
directory. You should also set your PATH to make sure the proper Java binaries
(the ones from the same kit) are found before any similar named commands.
Put the files in your shell rc file, .login or even install it system wide if
all are supposed to use Java.
Here are the commands for a bash shell:
export JAVA_HOME=/usr/java/jre1.3.1_06
export PATH=/usr/java/jre1.3.1_06/bin:$PATH
After you do this, test with:
echo $JAVA_HOME
-> /usr/java/jre1.3.1_06
which java
-> /usr/java/jre1.3.1_06/bin/java
Thanks for your interest in trying Visual Explain.
Regards,
Fernando
