[Play 2.4 java] There is no started application

[Paul Fauchon]

Hi, 

I'm trying to set up some file path based on the Play.application().path() in a controller like following:

private final String PNG_PATH = "cache/windowsTiles/";
private final String FULL_PNG_PATH = Play.application().path().getPath() + "/" + PNG_PATH;

but i'm having the following error:

play.api.UnexpectedException: Unexpected exception[ProvisionException: Unable to provision, see the following errors:
1) Error injecting constructor, java.lang.RuntimeException: There is no started application
at controllers.WindowsTiles.<init>(WindowsTiles.java:31)
while locating controllers.WindowsTiles
for parameter 2 at router.Routes.<init>(Routes.scala:60)

at play.api.DefaultApplication.class(Application.scala:240)
while locating play.api.DefaultApplication
while locating play.api.Application

It was working in Play 2.3.

Anyone got an idea of how I can instantiate a bunch of constants after the application has started ?

 To be honest I'm having a hard time making the transition to 2.4 and the dependency injection system even though I read the documentation, it's really not clear for me.

Regards,

Paul.

@Inject Configuration, and use that. In general, avoid using Play.* at all.
