16. OSGi and Groovy
Like we did with Scala, let’s say we want to use a dynamic language to improve the expressiveness and speed with which we develop the calculation implementation. In this case, we’ll replace the Scala version of calc-impl.jar
with a Groovy version.
16.1. Getting Started
Similar to what we did for the Scala calculation module, creating a Groovy1 version of the calculation won’t require any modifications to our existing system either. We’ll simply write the Groovy code, bundle the code into a calc-impl-groovy.jar
module, and deploy it. Again, we did a good job creating Cohesive Modules with a Default Implementation. Independent Deployment was also a strength of our design. So, now that we want to create the Groovy module, we ...
