Play 2.2.3 can not see file by Play.application().resource

Play 2.2.3. Windows 7.

public static Result menu() throws IOException {

    String path = Play.application().resource("resources/menu.json").toString();

    String content = Files.toString(new File(path), Charsets.UTF_8);

    return ok(content).as("JSON");
}

Got an error:

... scala-2.10\classes\resources\menu.json The filename, directory name, or volume label syntax is incorrect

Checking that path in file-system, I'm able to find my file there:

..\target\scala-2.10\classes\resources\menu.json

I'm able to find it there. Why play can't?

UPDATE: I've just figured out I can not create files on C:\ root folder on my machine. That maybe the issue. But on other hand I'm not accessing root folder, and ad trying to get read only access. And I do have write access to that file on that path anyway.

As actually you want to use your menu.json file as a static asset you can put it i.e. into public/resources/menu.json file and then read it with simple: 

<script>
    $.get('@routes.Assets.at("resources/menu.json")');
</script>

or just directly by request:

http://localhost:9000/assets/resources/menu.json

To do what you want via controller you need to read the InputStream by classpath (remember that finally it will be archived into jar file!) but it need to be placed in conf folder i.e.: conf/resources/menu.json then from controller:

public static Result menuViaControllerJson() {
    InputStream is = Play.application().classloader().getResourceAsStream("resources/menu.json");
    return (is != null)
            ? ok(is)
            : notFound();
}

Anyway you will get exactly the same result as for common Assets.at, so consider if it's worth of effort.

Edit: If you want to use this file as custom config just use HOCON syntax file i.e.: conf/ses.conf:

foo = "bar"

and in controller:

import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;

....

Config cfg = ConfigFactory.parseResources(Play.application().classloader(), "ses.conf");
debug("My 'foo' is configured as: " + cfg.getString("foo"));
