I've an apparently (silly) simple question:

With JRuby is it possible to deploy a single file Sinatra application?

I mean: I've my Sinatra app with all needed gems exploded into some `./vendor/lib` directory and I'd like to deploy the whole app as a single jar file to run on a deployment machine:

```
$ java jar my_app.jar

```

where the only thing I have is Java.

Is that possible? And, if so, there is a simple way to accomplish that?

TIA
