Problems with db driver during installation (newest release WAR from github)

[ray]

HI i am trying to install jobsworth on an ubuntu trusty server on AWS EC2.

 I am exactly following the readme at github, using a mysql db.

However, I get stuck when I open the URL.

Error message:

You're seeing this error because you use JRuby::Rack::ErrorApp::ShowStatus.

Any Hints ? Do I have to install sth additionally via package manger in ubuntu?

I'm trying to upgrade from 4.0 beta 3, to 4.0.1, and I'm getting a very similar error.

Before updating the ROOT.war, I updated my packages using aptitude and restarted tomcat7.  The old 4.0b3 application came back up no problem.

You're seeing this error because you use JRuby::Rack::ErrorApp::ShowStatus.

I'm experiencing both of these errors as well. Centos 7 server, Tomcat 7.0.54. I was able to fix the first ":url required" error manually, but now am getting the "cannot load Java class mysql.." error. Please help.
