I'll admit, this example was a bit contrived. In a real system, we would not manually output
XML or write all this boilerplate code to read in an XML document and convert it to a busi-
ness object, but I don't want to distract you from learning JAX-RS basics by introducing an-
other API. In Chapter 6 , I will show how you can use JAXB to map your Customer object to
XML and have JAX-RS automatically transform your HTTP message body to and from
XML.

JAX-RS and Java Interfaces
In our example so far, we've applied JAX-RS annotations directly on the Java class that im-
plements our service. In JAX-RS, you are also allowed to define a Java interface that con-
tains all your JAX-RS annotation metadata instead of applying all your annotations to your
implementation class.
