Second approach jersey ServletContainer from 1 version.

First approach:

 version="3.1">

<description>JerseyTesting</description>
<servlet-name>WebService</servlet-name>
<servlet-class>web.service.JerseyDemo</servlet-class>

// When i use this construction -> upper
//i got the response as needed! 

<description>JerseyTesting</description>
<servlet-name>WebService</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

//When i using this construction I got 404 not found, at the same url path!

 </servlet> 
 
//Here the mapping
  <servlet-mapping>
  <servlet-name>WebService</servlet-name>
  <url-pattern>/users/*</url-pattern>
  </servlet-mapping>

  </web-app>
Java Code:
// Using it with: And this working!
//<description>JerseyTesting</description>
//<servlet-name>WebService</servlet-name>
//<servlet-class>web.service.JerseyDemo</servlet-class>

@Path("users")
public class JerseyDemo extends HttpServlet{

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

   PrintWriter writer = resp.getWriter();
   writer.print("Hello from Servlet");

   }
  }
Java Code:
  // Using it with: And this not working 404 not found error!
  //<description>JerseyTesting</description>
    //<servlet-name>WebService</servlet-name>
    //<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

@Path("users")
public class JerseyDemo {


@GET
@Produces(MediaType.APPLICATION_JSON)
public String getResponse(){

    return "Hello From Jersey Servlet";
    }
 }
Here is the web folder with jars with first approach upper!

Java Code:
 <!--

  <servlet>
   <servlet-name>WebService</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
   <init-param>
   <param-name>com.sun.jersey.config.property.packages</param-name>
   <param-value>tests</param-value>
   </init-param>
   <load-on-startup>1</load-on-startup>
  </servlet>

   //This method not working!! 404 Error!

  -->

<servlet>
    <servlet-name>WebService</servlet-name>
    <servlet-class>tests.JerseyServiceDemo</servlet-class>
    <load-on-startup>1</load-on-startup>

   // This method Working!
</servlet>

<servlet-mapping>
    <servlet-name>WebService</servlet-name>
    <url-pattern>/users/*</url-pattern>
  </servlet-mapping>
