Hi Martin,
Thanks for your help. I have tried your hack but didn't work, still same
error,
class addfile (
$enable_notify => Service[’tomcat’],
) {
file {‘/tmp/hello’:
ensure => file,
notify => $enable_notify,
}
}
Technically, we can all any resource from any classes since all resources
are unique across modules.
Thanks,
Afroz Hussain
