You should definitely read through all the documentation here:
http://docs.jboss.org/resteasy/docs/3.0.17.Final/userguide/html_single/index.html
And take a look at the examples.
This is a bit of an old way of doing things, but based on what you have,
and the info here:
http://www.mkyong.com/webservices/jax-rs/resteasy-hello-world-example/
I got your example working. I did use maven (dependencies on RestEasy and
Jetty). But here are the files:
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/rest")
public class RootApplication extends Application
{
private Set<Object> singletons = new HashSet<Object>();
public RootApplication()
{
singletons.add(new HelloWorld());
}
@Override
public Set<Object> getSingletons()
{
return singletons;
}
}
import java.util.Date;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("hello")
public class HelloWorld
{
@GET
@Produces("text/plain")
public String helloResource()
{
return "Hello! It's " + new Date();
}
}
import java.io.File;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;
public class ReTest
{
public static void main(String[] args) throws Exception
{
WebAppContext context = new WebAppContext();
context.setDescriptor(new
File("resteasytest/src/main/webapp/WEB-INF/web.xml").getAbsolutePath());
context.setResourceBase(new
File("resteasytest/src/main/webapp").getAbsolutePath());
context.setContextPath("/");
Server server = new Server(8123);
server.setHandler(context);
server.start();
}
}

Running ReTest and going to:

Resulted in:
Hello! It's Fri Jun 03 12:30:47 EDT 2016

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
