Load file from '/conf' directory on Cloudbees

Question

What we do :

We run Play2 application on Cloudbees and we load a file from \'/conf\' directory (inside the classpath of the application).

These 2 snippets

Answer 1

Well, files in '/conf' are in the classpath and not on the filesystem so we need to load the file this way :

Play.application.resourceAsStream("myfile.json")
//.resource() also works - depends what we want

Note that we don't put "conf" in the path - files in there are on the classpath in the root.

Note that in production it comes from a jar/zip, not a file - so getFile is somewhat misleading in play.

Answer 2

It seems that Heroku run play apps via "play start" or "play run" which is not the recommended way for play apps to run in production - this explains why "conf" is visible there - although this could change in a future version of play.

Answer 3

I am using play 2.4. What works for me was

import play.Play;
import org.apache.commons.io.IOUtils;

  String myfile = IOUtils.toString(Play.application().resourceAsStream("myfile.json"));

NOTE: application() is called as a static method.
