Validator can't find draft-03.json when in a Warbler/JRuby jar

[drbobbeaty]

Set-Up

We are deploying a Ruby app with JRuby (1.6.7.2) and Warbler (1.3.6) as an executable jar. Standard JRuby 1.9 compatibility mode.

Problem

I don't believe that the Validator code is looking within the jar for the draft-03.json metaschema files:

The core part of the stack trace is the section:

Errno::ENOENT: No such file or directory - /Users/bbeaty/Developer/quantum-lead/quantum-lead.jar!/gems/json-schema-1.0.10/resources/draft-03.json

because we can see from the last line, the validator.rb file is being referenced from within the jar file, and then when it tries to find the draft-03.json file, it's in the normal filesystem.

It's not going to find the file because we deploy only the jar.
