3.1. Goals of REST Interface

The HornetQ REST interface allows you to leverage the reliability and scalability features of HornetQ over a simple REST/HTTP interface. Messages are produced and consumed by sending and receiving simple HTTP messages that contain the content you want to push around. For instance, here's a simple example of posting an order to an order processing queue express as an HTTP message:

POST /queue/orders/create HTTP/1.1
Host: example.com
Content-Type: application/xml

   <item>iPhone 4</item>

As you can see, we're just posting some arbitrary XML document to a URL. When the XML is received on the server is it processed within HornetQ as a JMS message and distributed through core HornetQ. Simple and easy. Consuming messages from a queue or topic looks very similar. We'll discuss the entire interface in detail later in this docbook.

Why would you want to use HornetQ's REST interface? What are the goals of the REST interface?
