Hi James,

Good to hear you've got it working.

Yes, there is some environment variable setting in the Apache config
file that you can set, but I can't remember what it is exactly -- you
might have to check the documentation. I just make sure I have Java on
my PATH before starting up the webserver, and it should inherit the
environment settings.

Regards,

Michael
