I am trying to get started with the salat plugin in playframework. I have configured the database in application.conf and added all the dependencies to Build.scala and added salat to the play.plugins file. I haven’t actually added any code to the project yet, I just followed the instructions on the github page, and then tried to run the project. I am getting the following error message

(Server started, use Ctrl+D to stop and go back to the console...)

I am stumped because I added my password and everything to the conf file. From the log it looks as though whatever is trying to connect to the database for me, is not logging in first, using the info I provided.

    I’ve the problem as well…

    it should come with the SalatPlugin’s onStart method that is requesting all database names: source._2.connection.getDatabaseNames().

    This code is just testing the aliveness of the server…

    I’m gonna check with leon how we could this differently! Sadly, you won’t be able to connect until this will be fixed!

    Stay tuned on this issue https://github.com/leon/play-salat/issues/23
