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!
