  How many ppl are gonna use this?

  I'm reluctant to do to this because it will require maintaining twice more code, in 2 languages. Mongrel already has a Java parser but we need to port all the changes to it. Plus I'm porting some parts of response writing to C. Writing extensions is already painful, writing it in 2 languages will be even more.

  If you'd like to use Thin on JRuby in production +1 the ticket. I'm putting on hold until I see lots of interest.

  +1 - We're using JRuby and looking for the best way to deploy. Thin looks great but it would have to support jRuby.

  I'm still trying to get Ruby allowed at work, and JRuby is probably the runtime I'd have to use. Count me a +1 vote.

  EM (trunk) has a java version, Rack seems to install OK on JRuby, so I imagine the parser is the only piece not already there. It seems it wouldn't be too much work to port the Mongrel java parser.

  I've started playing with this today, but MacPorts has Ragel 6.0, which has breaking changes from older versions, so the *.rl files from Mongrel don't work.

  I''m using Ragel 5.24, which I installed from source.

  This is clearly doable and since the parser doesn't change that much.

  But I wonder how EM performs on jruby. Anyone did some benchmarks?

  +1 ... considering the newest jruby smokes and has good gem compatibility at the moment. It seems ruby 1.9 is a ways off from real world usage, and many poor development souls stuck at companies, locked into using many jars can get the best of both worlds for internal / externals, while avoiding dirty, dirty java.

  we need EM to release for jruby before we can do anything.

  Yeah, finally!

  I'm working on a java-based backend for Thin. Not sure how it's going to work out because Thin depends on EM for more than just the backend. If we can divorce Thin from EM and constrain EM to backend code, then Thin on JRuby might really rock.

  Aman sent me this:

  fyi, i got the java reactor working

  http://github.com/tmm1/eventmach...

  ran some of my EM libraries through it and it seems to work without modifications or problems

  @kevin: Thin should not depend on EM anymore, only Backends::Base does depend on it. thin-turbo is a non-EM backend and is works fine.

  lib/thin.rb requires EM, and lib/thin/connection.rb has the Connection class extending EventMachine::Connection. Am I not looking at the right branch or something? I admit I haven't tried running Thin on JRuby without EM installed, but I didn't think I could yet. What am I missing?

• 

  macournoyer August 28th, 2008 @ 12:03 PM

  ah right, we can fix that by require all things EM in the Backends::Base, so it it's not loaded EM will not be required.

  Hm, but we'll need to tweak the gem to require EM gem only on non-jruby installation.

  Any better way to make EM optional?

• 

  Kevin Williams August 28th, 2008 @ 12:14 PM

  Perhaps have a safe alternate backend based on webrick or mongrel? The backend selection code could try to load the EM gem and choose a different backend if not found.

  That would probably mean creating an explicit EM backend, rather that putting EM stuff in Backends::Base.

  hello,

  How is going work with jruby support ? I saw java version of EM.

• 

  Kevin Williams December 22nd, 2008 @ 04:02 PM

  EM for JRuby isn't formally released, so I haven't tried to do anything yet. I'm continuing to working on getting something based on Mina to work. Almost got it now, just trying to figure out Rack and plugging the two together.

  pietia December 22nd, 2008 @ 04:27 PM

  Which version of Mine? Is your code available via net?

• 

  Kevin Williams December 22nd, 2008 @ 04:28 PM

  The latest version of Mina - no, I haven't released it yet.
