I’m trying to design an app that has a service based using the template of the [Hello World](https://github.com/webOS-TV-app-samples/HelloWorldService) app. My question is how do I ensure that my service (and its associated method) can be called from the Luna bus? My target platform is a TV so I don’t know how relevant OSE is.

Thanks. Turns out I wasn’t packaging correctly. Side note do you how to increase volume via the luna bus? It seems like

```auto
luna-send -n 1 -f luna://com.webos.audio/sendVol

```

should work but it doesn’t.

What part is OSE? The luna-send command or the service-ID?

[luna-send](https://www.webosose.org/docs/tools/commands/luna-send/) is a command-line tool for webOS OSE.
