beginner Java REST 404 error

Newbie in trying to set up a REST service in Java. I created a simple java program and deployed the war file in apache-tomcat-8.5.5 (under the apache-tomcat-8.5.5\webapps dir). But when I try to access the REST service (http://localhost:8081/SampleRS/rest/sampproj/uservalue), get a 404 error. (Starting the tomcat on port 8081 {Had wanted to do a POST - using Postman,but was getting error, then added a GET method to verify, but still got error)

The Java file:

package sampproj; import javax.ws.rs.Consumes; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.GET; import javax.ws.rs.Produces; import javax.ws.rs.PathParam; @Path("sampproj") public class WSPostSer { public WSPostSer() { super(); } @POST @Consumes("application/json") @Path("devpost") public String createTemp (String devName){ System.out.println (" in reate"); return "heloo" + devName; } @GET @Produces("text/plain") @Path("/uservalue") public String welcomeResource (@PathParam("uservalue") String username){ System.out.println(" welcomeResource "); return "heloo Get " + username; } } 

The web xml is

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SampleRS</display-name> <servlet> <servlet-name>Jersey RESTful Application</servlet-name> <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> <init-param> <param-name>jersey.config.server.provider.packages</param-name> <param-value>sampproj</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>Jersey RESTful Application</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> </web-app>
