I’m happy to announce the JRuby Extras project, on RubyForge as jruby-extras. This project is intended to be a community-maintained nursery of plugins and extensions to extend JRuby’s capabilities and to provide Java-based versions of many popular C extensions. Here’s a short list of projects to be nurtured under the JRuby Extras banner: - A Mongrel for JRuby, with Java-based http11 and tst extensions - An ActiveRecord JDBC adapter, which will eventually promise full database independence for Rails apps - A set of Java-aware Rake tasks to finally allow poor, sad Java developers to eliminate ten-thousand-line Ant scripts for their builds - An “AntBuilder” project, to allow defining those ten-thousand-line ant scripts in something less similar to angle-bracket insanity - And much more to come! JRuby opens up a whole new world to Rubyists, but there are little gaps to fill to support all the popular apps. JRuby Extras will be the answer to those gaps. Success for Ruby on the JVM means more success for Ruby overall…and that’s what we all want, isn’t it? Anyone interested in porting an extension to Java or making their favorite Ruby app run under JRuby should join the project! Visit jruby-extras at RubyForge: [http://rubyforge.org/projects/jruby-extras/](http://rubyforge.org/projects/jruby-extras/) And for those of you interested, JRuby has moved to Codehaus as of this week. We’re blazing ahead on performance and compatibility initiatives, and the future is looking great for Ruby on the JVM. Visit [http://www.jruby.org](http://www.jruby.org) Thank you! ---

The code for this is in the svn, ask me for help getting it. Also, please please please please please please please please please please please please please please please please don’t don’t don’t don’t don’t don’t don’t don’t don’t don’t … hand code the HTTP parser. Use a parser generator. Anyway, feel free to hit me up for help. ---

Well, the TST took only 1 hour to port, so I believe it’s OK to waste that time. Regarding the parser, we’ve discussed it back and forth. The problem is that Ragel isn’t available on Java yet. But hand coding it was never an option (I’ve read your statements about how many security holes get fixed by having a parser generator). Right now Danny Lagrouw have created a JavaCC version which seems really good. No worries, we want Mongrel on JRuby because it’s _good_ at what it does, so it would defeat our purposes to change any of that. – Ola B.

The best way you could probably help us is paving the way for this to be included in mongrel-core at some point. Ideally we’d eventually like Ruby and JRuby users alike to just install the same gems, knowing they’ll come along with the appropriate native bits for the target implementation. That’s the big goal, anyway…avoiding JRuby forks of all the same projects. ---

Regarding the parser, we’ve discussed it back and forth. That’s cool, but the problem isn’t how easy it is to write, the problem is that \_why wrote a completely different URI classifier that allows for nicer notifiers and registrations and all in pure Ruby. It’s in the 0.4 code, so your work was basically for nothing really. We should maybe coordinate on this a bit so that you folks get the right code to base your work on and we can sync up with the 0.4 release. ---

Absolutely…I think the jruby-extras devs involved in the mongrel effort should connect with y’all and do it up right. Thanks for the help!
