servlet-class path in web.xml

I am following http://ift.tt/1fo0HcC tutorial.

I have created the project(Dyanamic web project) by name "JerseyDemoProject",created a package by name "Package1" and i have written the program Hello.java(which is given in the tutorial) in this package.

I have modified my web.xml as follows

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://ift.tt/ra1lAU" xmlns="http://ift.tt/nSRXKP" xmlns:web="http://ift.tt/LU8AHS" xsi:schemaLocation="http://ift.tt/nSRXKP http://ift.tt/1eWqHMP" id="WebApp_ID" version="3.0">
  <display-name>JerseyDemoProject</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>

   <servlet>
    <servlet-name>HelloServlet</servlet-name>
    <servlet-class>Package1.Hello</servlet-class>
    <init-param>
      <param-name>jersey.config.server.provider.packages</param-name>
      <param-value>Package1</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>HelloServlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
