| <p>Definir un servicio Rest es muy fácil, simplemente necesitamos agregar la anotación <code>@Path</code> en la clase y después definir los métodos HTTP que vamos a usar (<code>@GET</code>, <code>@POST</code>, …).</p> |

| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>Aquí tenemos un REST simple, anotamos la clase con <code>@Path("/greeting")</code> para indicar la ruta correspondiente a la clase <code>GreetingService</code>. Definimos <code>message()</code> como <code>@GET</code> y <code>lowerCase()</code> como <code>@POST</code> para la ruta <code>/greeting</code>. Pronto tenemos un servicio, muy simple ¿verdad?</p> |

| <div class="paragraph"> |
| <p>Usamos el OpenEJB ApplicationComposer para facilitar la prueba.</p> |

| <div class="paragraph"> |
| <p>La idea primero es activar los servicios jaxrs. Esto se hace utilizando la anotación <code>@EnableServices</code>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Entonces creamos la aplicación simplemente devolviendo un objeto representando el <code>web.xml</code>. Aquí simplemente lo utilizamos para definir el contexto raíz, pero también puede ser utilizado para definir la aplicación REST. Y para completar la definición de la aplicación agregamos la anotación <code>@Classes</code> para definir el conjunto de clases a ser utilizado en esta app.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Finalmente para probarlo utilizamos la API cliente de <code>cxf</code> para llamar el servicio REST en los métodos <code>get()</code> y <code>post()</code>.</p> |
