Groovy, JRuby, Scala, and Clojure are some of the most widely used alternative Java Virtual Machine (JVM) languages today. I spoke with several developers who adopted one of these languages in a Java-based project. This article ("Alternative JVM Languages for Java Projects") tells their stories - which language they picked, why they picked it, and how they integrated it with their existing Java code base or infrastructure.
This article includes stories from the following people:
- Moss Collum: Gradually migrating code from Java to Groovy
- Kris Nuttycombe: Starting to use Scala to write tests for a Java project
- Najati Imam: Seamlessly deploying JRuby on Rails in an existing Java infrastructure
- Bob McWhirter: Combining some of the best parts of Java with Ruby language to build something new: TorqueBox
- Dan Chamberlain: Using Clojure to more naturally and succinctly model the business problem domain
