This is done in ubuntu 14.04. The app works as it should -no errors- when installed to other systems with same setup (os, jvm, rvm, jruby version). I'm suspecting that this has something to do with the paths of the jar files themselves. Any suggestions?
Problem solved when I removed jruby at all and reinstall by also stating the ruby.
rvm install jruby --1.9
This time the gem was installed along with the jar dependencies.
