Opposite of rails initializers (2.xx)?
I run several daemons in config/initializers/ when I start my rails app, but I need a way to detect when the app is shutting down, and stop the daemons. Are there any hooks / places where I can do this? ...

I'm trying to convert a rails app to jruby on rails. Currently, jruby script/delayed_job run gives: /usr/lib/jruby/lib/ruby/gems/1.8/gems/delayed_job-2.0.3/lib/delayed/command.rb:50:in `each_object': ObjectSpace is disabled; each_object will only work with Class, pass -X+O to enable (RuntimeError) from /usr/lib/jruby/lib/ruby/gems/1...
So the loose tolerance of Ruby to use braces sometimes and not REQUIRE them has led to alot of confusion for me as I'm trying to learn Rails and when/where to use each and why? Sometimes parameters or values are passed as (@user, @comment) and other times they seem to be [ :user => comment ] and still others it's just: :action => 'edit'...
Background: I have a java library that is accessed by many developers - usually via java. However, a few devs hope to access this via a Ruby API. I am gravitating in the direction of Jruby in order to implement a Java-Ruby API. Questions: My main concern is that these developers will not be able to utilize the API in their current, R...

I'm interested in promoting JRuby in our office as the platform hosting Rails applications. But how reliable is it? Is its performance better than MRI 1.8.7? JRuby 1.5 states that it is 100% compatible with Ruby 1.8.7, does this mean that JRuby can run any Ruby/Rails code? ...

I have done a few projects using Ruby on Rails. I am going to use JRuby on Rails and hosting it on GAE. In that case what are the stuff that I need to know while developing JRuby apps.

I've spent the last 9 months using Ruby on Rails exclusively. I've been asked to join project and they are currently using Struts with Tomcat. I've done Java in the past and vowed never to go back for several reasons. They are currently having trouble finding people who know Java or are willing to join a project that uses it. (This is w...
I've seen http://github.com/muness/migration_sql_generator, but it doesn't work properly with MySQL for certain important operations. Is there any other way we can capture the sql generated during a rails migration? The reason I'm asking is that I cannot run the migrations on the production server since it is maintained by technical sup...

I've been having a tough time getting jRuby on Rails 3 deployed on Tomcat 6. I got it to work exactly once. I modified my database.yaml and Gemfile to check for jRuby, something like this: if defined?(JRUBY_VERSION) gem 'jdbc-mysql' #gem 'jdbc-sqlite3' gem 'activerecord-jdbc-adapter' gem 'activerecord-jdbcmysql-adapter'...
I just started with JRuby on Rails and absolutely love it. I know how to use current classes within the Java API in my Rails app, but if I wanted to create a new custom class written in purely Java code, how would I be able to use it in my Rails app? For example, let's say I created Dog.java: class Dog { private String name; publi...
For a RoR web project I am building the component stack. Because I want to share some cached business objects between requests and sessions of the same application I planned not to use the Rails/Mongrel shared nothing principle and switch over to JRuby for the first time. (No, I do not want an extra process like memcached). My idea so fa...
