playframework - 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 work in local and at heroku

Play.application().getFile("conf/myfile.json")

and

new File("conf/myfile.json")

However, on Cloudbees, we get FileNotFoundException :

java.io.FileNotFoundException: /var/genapp/apps/..../conf/myfile.json (No such file or directory)

So how to load a file from classpath on Cloudbees?

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.
