Chapter 12. Groovy Programming

We are going to build a simple web service in Groovy using the popular Vert.x microservice framework. Our program will make use of the H2 Database Management System (DBMS), a database system that is fully written in Java. We will use the Java Database Connectivity (JDBC) standard to interact with H2. XML will be generated using Groovy's MarkupBuilder, a class that is offered in the Groovy Development Kit (GDK), Groovy's runtime library.

This time, we will not use an external build tool responsible for building the project; instead, we'll let the Eclipse IDE handle this job for us. We will be needing some external dependencies (to use the mentioned H2 and Vert.x open source projects) and will use Apache Ivy for this. The Eclipse IDE does not come with Groovy support out of the box, so we need to install a plugin for this language as well. The following topics will be covered in this chapter:

Installing the Groovy Eclipse plugin
Apache Ivy and IvyDE plugin for Eclipse...
