I recently uploaded Play application on server. Problem is that I can ran application through command activator run it compiles and runs fine. When I try to do activator clean stage it also compiles but after target/universal/stage/bin/name_of_myapp it throws an error like
Oops, cannot start the server.

Java version on server is 1.7.x when mine is 1.8.0_31 I can't upgrade Java version on server
Problem resolved. It was Java version on server being different than mine. After moving project to server I had to compile it with ./activator clean later ./activator compile so it was compiled under server Java. Now I am able to generate working stag and run it without error
