jruby-rack-standalone-jetty

Provides a way to run jruby-rack with an embedded jetty, no WAR files or separate servlet container needed. You simply write a launcher script that contains code like this:

require 'jetty-runner'

jetty_options = {
  :host => 'localhost',
  :port => 4567,
  # jruby-rack context parameters:
  'jruby.rack.layout_class' => 'RailsFilesystemLayout',
  'gem.path' => '.',
  'rackup' => IO.read('config.ru')
}

server = JettyRunner.new(jetty_options)
server.run
server.join 

The options hash supports all jruby-rack context parameters.

Supported Jetty options:

• :host The IP to bind to. localhost by default.
• :port The port to use. If not specified then Jetty will use a random one.
• :use_nio Whether to use NIO instead of blocking IO for HTTP (does not affect HTTPS). true by default
• :min_threads The minimum number of threads. 10 by default.
• :max_threads The maximum number of threads. 200 by default.
• :low_threads The number of threads that are considered to be low. 50 by default.
• :accept_queue_size The number of requests to be allowed in the accept queue. Uses the value of :max_threads by default.
• :ssl_port The HTTPS port. If not specified (along with :keystore and :key_password) then HTTPS will not be enabled.
• :keystore The keystore. If not specified (along with :ssl_port and :key_password) then HTTPS will not be enabled.
• :key_password The password for the key in the keystore. If not specified (along with :ssl_port and :keystore) then HTTPS will not be enabled.
• :keystore_type The type of the keystore. JKS by default.
• :with_stats Whether to enable Jetty statistics and expose them via JMX. true by default.
• :request_log The request log object to use (must implement org.mortbay.jetty.RequestLog). If neither this nor :request_log_path are specified, then request logging will not be enabled.
• :request_log_path The path where the NCSARequestLog should log to. If neither this nor :request_log are specified, then request logging will not be enabled.
• :resource_base Base folder for resolving resources (such as config.ru). Default is ..

Dependencies

This library requires that jetty 6.1.x and jruby-rack are in the classpath (it does not bundle them).
