Groovy is a dynamic language for the Java platform that improves developer productivity thanks to a concise syntax similar to Python, Ruby, and Perl. This document provides steps to create a Mule project that uses a Groovy script component to print "demo payload" to the console when an HTTP request is made to localhost:8081/demo. The project is configured with an HTTP listener connected to a flow containing the Groovy component with a simple script to print the message.
