Answer 1

One thing that you could do would be to modify the catalina.sh (Unix based) or the catalina.bat (windows based).

Within each of the scripts you can set certain variables which only processes created under the shell will inherit. So for catalina.sh, use the following line:

export JAVA_HOME="intented java home"

And for windows use

set JAVA_HOME="intented java home"
