/**
 * A main class to start Apache CXF with our REST service {@link RestOrderService} using Swagger.
 * <p/>
 * This main class uses Apache CXF in pure Java code without any XML configuration.
 * Notice this configuration requires a bit of Java code, and more advanced configuration
 * and usage of Apache CXF often involves configuration in XML files
 * (due CXF was very Spring XML in the start of its lifetime).
 * <p/>
 * This server uses an embedded Jetty server to setup a CXF servlet that bootstraps
 * a JAX-RS application {@link RestOrderApplication}.
