> +Question:+
> Cygnus not starting as a service
> +Description:+
> I've been checking other people's questions regarding config files for cygnus, but still I couldn't make mine work.
> Starting cygnus with "service cygnus start" fails.
> When I try to start the service the log at /var/log/cygnus/cygnus.log says:
> Warning: JAVA_HOME is not set!
