Initialize JAX-RS in Jetty

JAXRSService.java

      Server server = new Server(config.getPort());
      final ContextHandlerCollection contexts = new ContextHandlerCollection();
      server.setHandler(contexts);
      ServletHolder jaxrs = new ServletHolder(ServletContainer.class);
      jaxrs.setInitParameter("javax.ws.rs.Application", applicationClassName);
      final ServletContextHandler mainHandler = new ServletContextHandler(contexts, "/", true, false);
      mainHandler.addServlet(jaxrs, "/*");

Quick question on imports: which ones are from Jetty vs JAX-RS (Jersey?)

import com.sun.jersey.spi.container.servlet.ServletContainer;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.ContextHandlerCollection;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
