JRuby: What, Why, How ... Do it Now

  • Ruby, simple, productive, and fun.
  • main language is writen in C
  • pure object oriented language, no primitives
  • dynamically typed, "duck typing". very loosely typed
  • classes and modules, single inheritence
  • blocks ... anonymous methods, pass around and invoke
  • quick tour: metaprogramming, open classes, special handlers
  • JRuby: it's just ruby on top of the Java platform, improvements: native threading, better performance
  • Interactive Ruby Demo:
  • What are people doing with JRuby?
    • Swing: framework tools / projects: cheri, monkeybars
    • Tooling: NetBeans is the most popular
    • Pretty Graphics: ruby-processing library
  • Intoducing Ruby on Rails:
    • full stack web framework (MVC)
    • written in ruby
    • convention over configuration
    • don't repeat yourself, how DRY is your code
    • agile development environment
  • Why JRuby on Rails
    • greatly simplified application development
    • create apps quicky
    • deploy to app server
    • easy integration with exiting java technology
    • better performance
  • Production JRuby on Rails
    • Oracle's Mix
    • Suns Mediacast
    • ThoughtWorks' Mingle
    • Sonar - code/project analysis tool

JAX-RS: The Java API for RESTful Web Services

  • REST Primer
  • www.inoq.com
  • Give everything an ID ... a URI, everything has to have one
  • Link things together, send receive data
  • use standard methods: GET, POST, PUT, DELETE
  • multiple representations:
    • formats: XML, JSON, XHTML
    • maximize reach
    • support content negotiation:
  • stateless communications, long lived identifiers, avoid sessions, all needed data is within the request
  • common patterns;
    • Container, Item example: Atom publishing protocol
    • Map, Key, Value: example: Amazon S3
  • Key benefits:
    • server side: scaling, straightforward failover, cacheable, reduced coupling
    • client side: bookmarkable, experiment in browser, broad language support, choice of data formats
  • Everything is an ID
    • Thing == resource class
    • ID provided by @Path annotation
  • Link Things together
    • UriInfo, info about deployment context
    • UriBuilder, construct URIs
  • Use std methods
    • @GET, @POST, @PUT, @DELETE, @HEAD
    • @HttpMethod
  • Mutiple repesentations:
    • @PRoduceMime, @ConsumeMime
  • Demo: expose java system properties
  • Need to get the firefox plugin called "poster", very cool
  • JavaSE RuntimeDelegate
  • Jersey supports Grizzly
  • In public review, july final draft, final release in september
  • BOF @ 8:30 BOF-5613 - Jersey: RESTful Web Services Made Easy
