404 Error with RESTful webservice using Jersey - jersey

Question

I have been spending hours trying to figure out why I am gettin 404 error. I have checked similar postings in Stackoverflow, but I am still having a problem.
I know it runs on Tomcat and can display index file. But, when I try to test RESTful ws with the following url, http://localhost:8080/RestWs/rest/hello,
I get 404 error:
My web.xml:

My resource class in Java:
package DemoRest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("/hello")
public class HelloResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String sayHello() {
return "Hello Jersey";
}
}
I downloaded Jersey jars from https://jersey.github.io/download.html#
and copied the jars in the WEB/INF/lib folder.
The extracted jaxrs-ri-2.26 jar has three folders - api, ext and lib. I copied all jars from these folders to the WEB/INF/lib folder.
I am wondering if I am missing some jars or they are not in a right location. However, I checked most of the related postings in the stackoverflow for solution, but I was not successful.
I appreciate any help.

I solved my problem. One solution I found worked. I had to download JaxWs jar from https://github.com/javaee/metro-jax-ws and copy jaxws-rt.jar into Tomcat lib folder.
