  • 18. JRuby call Ruby from Java or Java from Ruby lots of sub-projects emerging better scalability with native threading native unicode support
  • 19. JRuby specialized JRuby offerings are appearing...
  • 20. The good gets better
  • 21. 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!
  • 22. JRuby on Rails

  • 35. JRoR on Spring rake war:standalone:create in action:
  • 36. JRoR on Spring generated WARs work on many servers: ✓Tomcat ✓Glassfish ✓Jetty ✓JBoss
  • 37. JRoR on Spring ✓ add Chris’ Spring module:
  • 38. JRoR on Spring ✓ Expand the generated WAR ✓Add Spring application ➡ Application Code ➡ Libraries (Jars) ➡ Config Files
  • 39. JRoR on Spring ✓ access your Spring beans from a RoR controller
  • 40. 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
