JRuby-Rack Examples

This directory includes samples using JRuby-Rack to build Rack web applications for deployment into Java app servers.

• All use Warbler to do so for easy of packaging.
• Require JRuby 10.0 and a compatible JVM (Java 21 -> 25).

Building/running

For deployment into a separate webserver:

1.  rm -f Gemfile.lock && bundle install && bundle exec warble war

2. Drop the war into a relevant Java app server running a compatible JVM version

As an executable jar within Jetty:

1.  rm -f Gemfile.lock && bundle install && bundle exec warble executable war

2.  java -Dwarbler.debug=true -Dwarbler.port=8989 -jar *.war

Development

You can run the examples using local source for warbler or jruby-rack by

• Uncommenting the relevant path: suffixes in the example Gemfiles.
• (For Warbler) Build from source first, since its booting jar files are not committed to source
• (For jruby-rack) Build from source first, since it does not define a gemspec
