[Jruby-extras-devel] Pleasantly surprised at rails-integration

[Charles Oliver Nutter]

This evening I started thinking about the Grizzly support for running 
Rails, and it occurred to me that there must be a better way than 
calling Rails own dispatcher directly. Specifically, it seemed wasted 
overhead to use Ruby's CGI library to process requests and responses 
when the container would do that for you.

As I started to look into what would be required to implement a more 
direct request and response model, I thought I'd see if the 
rails-integration code does that. Naturally, it has beaten me to the punch.

I'm no rails expert, so tell me how close I am on this...

rails-integration provides servlet-based implementations of 
ActionController::AbstractRequest based on HttpServletRequest and 
HttpServletResponse. It maps all calls through as appropriate and avoids 
re-parsing or re-handling request and response headers. By doing this it 
also skips a large portion of the request processing that normally slows 
down Rails.

Am I on the right track here?

This is really great stuff guys, and has potential to beat even servers 
like Mongrel in performance (since we're relying on tried-and-true Java 
servers to handle all the HTTP nonsense, rather than Ruby's CGI library).

So what's the status today? I have not been able to get a WAR'ed up 
Rails app working...is there a walkthrough somewhere on how to do it? 
(it should be in the JRuby wiki somewhere, methinks).

Get me going on this stuff and I'll buy y'all a beer some day. Oh, and 
I'll start using it and making contribution to the code.
