Rails to Java via REST

Rails to Java via REST - By Brian Leonard

Brian Leonard has written "Rails to Java via REST," detailing how he used Netbeans to write a REST service for a JPA entity bean, and used it from a Rails application: 

Since I've been studying the Rails framework, I've had an interest in integration with Java. Yes, JRuby is one possible solution, but if you have some large Java system that you want to integrate with, it' unlikely that you're just going to get the jar files to access that system's APIs. More likely is that system will expose itself as a service, and the service type du jour is REST.

So, in this entry I'm going to expose an entity class as a RESTful web service and then create a Rails client for that entity.

Setting Things Up

  • Download and install NetBeans 6.0 M10. Grab the Full distribution so you can get the Java IDE, Ruby and GlassFish.
  • Download and install the SWDP to GlassFish. This is required to create the RESTful web service.

Creating the RESTful Web Service

Here we'll expose the manufacturer table as a RESTful web service.

Create the Manufacturer Entity Class

  • Start NetBeans 6.0 and create a new Web Application named Manufacturers.
  • Right-click the project and select Entity Classes from Database.
  • Select jdbc/sample as the Data Source and MANUFACTURER as the Table (your list of available tables will be different then mine, but you should have MANUFACTURER):
