simple example using resteasy-jaxrs not working - jax-rs

Question

I can't get the message "hello" when I visit the page.
package jaxrs.ressources;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("greeting")
public class HelloRessource {
#GET
#Path("hello")
#Produces(MediaType.TEXT_PLAIN)
public String sayhello() {
return "Hello from JAX-RS";
}}
and this class
package jaxrs.utilities;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("/rest")
public class RestActivator extends Application{
}
The url http://127.0.0.1:8383/JAXRS_Hello_GL-1.0/rest/greeting/hello always displays "not found"
Is there any solution ?

Answer 1

Can you add the initializer:
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-servlet-initializer</artifactId>
<version>3.1.4.Final</version>
</dependency>
