Make your rails app launch the web browser when starting

In jruby, if you ever want to start the browser pointing to your application's base index page after rails finishes initialzing your application, you can take advantage of java.awt.Desktop::desktop.browse. java.awt.Desktop::desktop.browse will open the default OS's browser and point it to an URL you pass to it (tested on Windows, failed in Ubuntu+Firefox, don't know if it works on MacOSX or Solaris). Add these lines at the end of environment.rb to launch the browser:

include Java
java.awt.Desktop::desktop.browse(
java.net.URI.new('http://localhost:3000'))

In my case, it was complaining that "SSH host key finger-print xxx format is not supported. It must be in 'MD5' format". I had provided the sha fingerprint that WinScp shows. Instead, I needed to use the MD5 version of the fingerprint. To get that, I had to run in command line (I was in a folder that had openssh in it): ssh -o FingerprintHash=md5 mysftpsite.com To get the fingerprint in MD5 format.
