You need a Java Runtime Environment to run the Solr server

Fix:
Modify C:\Ruby192\lib\ruby\gems\1.9.1\gems\sunspot_solr-1.3.0\lib\sunspot\solr\java.rb file with

module Sunspot
  module Solr
    module Java
      def self.installed?
          true
      end
    end
  end
end

Also make sure your gemfile has:

gem 'sunspot_rails'
# This is an optional packaged Solr:
group :test, :development do
  gem 'sunspot_solr'
end
