Hi all,

I would like to develop an application that combines JRuby, Rails and Neo4j. When trying to use the latest version of Rails (5.0.0.beta1), I get a complaint regarding a missing activesupport gem. Well, after switching to Rails 4.2.6, and installing neo4j, I ran into the following problems, for which I also hereby report the temporary solutions:

  1. START NEO4j: be rake neo4j:start

    ====> PROB: NameError: uninitialized constant ActiveSupport::EventedFileUpdateChecker

     I disabled the "line config.file_watcher = ActiveSupport::EventedFileUpdateChecker" in config/environments/development.rb

THEN re-ran 1)

===> PROB: NoMethodError: undefined method `to_time_preserves_timezone=' for ActiveSupport:Module

	commented out the line ActiveSupport.to_time_preserves_timezone = true in config/initializers/new_framework_defaults.rb:15

THEN re-ran 1)

===> PROB: NoMethodError: undefined method `halt_callback_chains_on_return_false=' for ActiveSupport:Module

	commented out the line config/initializers/new_framework_defaults.rb:18

THEN re-ran 1)

===> PROB: NoMethodError: undefined method `perform_caching=’ for ActionMailer::Base:Class

	Set config.action_mailer.perform_caching = true (originally false) on line 32 of config/development

	// from https://github.com/rails/rails/issues/17657

	BUT IT DID NOT HELP

	1) I then commentd out this line in config/application.rb: require "action_mailer/railtie"

	2) commented ou the following lines in config/environments/development

		config.action_mailer.raise_delivery_errors = false

		config.action_mailer.perform_caching = false

OK, at this point, I managed to start neo4j with rake neo4j:start without any more issue

  1. THEN, I ran “rails s” to start the rails server, after generatin a model, a controller, and a view. Unfortunately, I ran into the following issue reported below:
