    Rails On Spring Rails On Spring Presentation Transcript

    • Rails on Spring Using JRuby as the Secret Sauce Brian Sam-Bodden
    • Agenda The State of Java and JEE Ruby on Rails to the Rescue Ruby makes Rails possible The Spring Framework
    • Agenda JRuby - Ruby on Steroids JRuby on Rails JRuby for Rapid Spring Prototyping JRuby on Rails and Spring
    • The State of Java and JEE
    • Java & JEE the most prevalent language the most complete enterprise platform a rich ecosystem of web frameworks a vibrant open source community
    • Java & JEE plagued by mediocre web frameworks not well suited for rapid prototyping in need of a dynamic language web framework one level of abstraction too low for the web
    • Who could help Java on the Web Tier?
    • Ruby on Rails a revolutionary web framework complete MVC solution fast prototyping killer AJAX support
    • Ruby on Rails a DSL for the web leading the pack on the web 2.0 front born from a product, not a committee a vibrant open source community
    • Ruby makes Rails possible
    • ✓Object-Oriented ✓Elegant ✓General Purpose ✓ Multi-paradigm Ruby ✓ Interpreted is... ✓Reflective ✓Dynamic ✓ Garbage-collected
    • The Spring Framework A breath of fresh air for Java
    • The Spring Framework is a layered Java/J2EE application framework is a lightweight IoC and AOP framework is one level of abstraction up from JEE is the leading framework to build enterprise applications
    • The Spring Framework let’s you use all of the power of JEE integrates seamlessly with Hibernate POJO-based development keeps your code clean harnesses the power of IoC and AOP
    • The Spring Framework Spring 2.0 supports dynamic languages support for JRuby, Groovy and BeanShell beans can be backed by dynamic languages scripted MVC controllers
    • JRuby Ruby on Steroids
    • JRuby 100% pure-Java implementation of Ruby brings Ruby to the JVM started in 2002, now under Sun’s auspice open source with a growing community
    • JRuby call Ruby from Java or Java from Ruby lots of sub-projects emerging better scalability with native threading native unicode support
    • JRuby specialized JRuby offerings are appearing...
    • The good gets better
    • JRuby on Rails the agility of rails - the scalability of Java JRuby likely to surpass Ruby in speed sneak Ruby and RoR into the enterprise!
    • JRuby on Rails
    • JRuby on Rails
    • JRuby on Rails JEE servers are good at scaling up no more multi-process management use JRuby “multi-VM” support leverage the maturity of the JVM and JEE servers
    • JRuby on Rails deploy your Rails app as a WAR leverage JDBC from ActiveRecord
    • JRuby For Rapid Spring Prototyping ...one way of sneaking Ruby in through the back door
    • JRuby+Spring RAD a simple example by the folks at jobster use JRuby for rapid prototyping Spring controller that delegates to a JRuby controller JRuby controllers live alongside your JSPs
    • JRuby+Spring RAD Simple JRuby controller
    • JRuby+Spring RAD JSP view provides input to the Ruby controller
    • JRuby+Spring RAD JSP view provides input to the Ruby controller
    • JRuby+Spring RAD this experimental library supports: ✓access to Spring beans from JRuby code ✓ access to Hibernate queries
    • The Perfect Pairing for a Java Shop JRuby on Rails + Spring
    • JRoR on Spring Chris Nelson’s work ✓use rails-integration plugin ✓ expose WebApplicationContext in a RoR controller ✓include Spring - Spring plugin for JRuby
    • JRoR on Spring ✓install goldspike rails-integration plugin on you JRoR app ✓ rake war:standalone:create to package a WAR with: ➡Your RoR app ➡JRuby and Rails libraries
    • JRoR on Spring rake war:standalone:create in action:
    • JRoR on Spring generated WARs work on many servers: ✓Tomcat ✓Glassfish ✓Jetty ✓JBoss
    • JRoR on Spring ✓ add Chris’ Spring module:
    • JRoR on Spring ✓ Expand the generated WAR ✓Add Spring application ➡ Application Code ➡ Libraries (Jars) ➡ Config Files
    • JRoR on Spring ✓ access your Spring beans from a RoR controller
    • JRoR on Spring ✓add a new face to your Spring applications ✓ leverage thousands of open source projects ✓leverage the good parts of JEE like JDBC and JMS
