Sessions not working in Sinatra app when packaged with warbler - sinatra

Question

I've created a simple sinatra app, but can't get sessions to work when running it as an executable war.
I've verified that it works when run via "jruby -S rackup", but when run with "java -jar myapp.war", I find that the session is reset on each request:

Other than setting sessions to be enabled, is there any special setup that is needed to have sessions work when the app is packaged with warbler and run as an executable war?

Answer 1

nothing special should be needed - I tried your sample and it worked fine.
it's probably a bug with the jruby-rack version you're using ... please try >= 1.1.15
also I would recommend to try out the jetty webserver (you'll find an option at config/warbler.rb) ... I'll try to make sure jetty is the default for a future Warbler version.
