# Simplest Possible REST Endpoint

The following GET-request:


http://localhost:8080/hello-rest/resources/message


invokes the method whatever:


import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("message")
public class MessageResource {
    @GET
    public String whatever() {
        return "hey, duke!";
    }
}


from a WAR with th name hello-rest and configured application path:


import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("resources")
public class JAXRSConfiguration extends Application {}


You only need a single dependency to compile the sample:


<dependency>
	<groupId>javax</groupId>
	<artifactId>javaee-api</artifactId>
	<version>7.0</version>
	<scope>provided</scope>
</dependency>



No further configuration is required
No XML is involved (web.xml is not needed)
The size of the hello-rest.war is 3.2 kB
Deployment takes milliseconds

Optional speedup: Java EE 7 essential archetype would create an empty maven project for you.
