Re: [Resteasy-users] (no subject)

[Sean D. <sea...@gm...>]

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:
http://localhost:8123/hello


Resulted in:

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