Setting up a JPA provider for your project
In enterprise applications, data is persisted in one or more data stores. JPA provides a standard API for managing data in relational databases. In this task we'll look at the persistence setup command to configure a JPA persistence provider for a Roo project.
Getting ready
Create a sub-directory ch02-recipes inside the C:\roo-cookbook directory.
To set up a JPA provider, we first need to create a Roo project. To create a new Roo project, download ch02.roo file from the book's website and copy it to the ch02-recipes directory.
Open the command prompt and go to the ch02-recipes directory. Now, start the Roo shell and execute commands in ch02.roo script using the script command, as explained in the Creating application artifacts from a Roo script recipe of Chapter 1. Successful execution of the ch02.roo script creates a flight-app Eclipse project which you can import in your Eclipse IDE.
