Timed access restriction in jsp

Question

Dear Friends,
While working on a website development, I've faced the following problem:-
I want to display a Webpage (written in HTML and JSP) in between a particular timing. [e.g. the page will be displayed in between 09:45 AM to 11:30 AM and again from 01:30 PM to 02:45 PM]. But except that particular duration, that page won't be displayed. Rather then an error page will be generated stating that you accessed that page in wrong time!! This task is essential for my project, but actually I don't know how to do it. Can anyone help me please!!! I'll be very greatful to all of those persons who can help me by giving advice or any type of suggestion.
Thanks in advance,
Abhinandan Banik

Here's an example of the filter :
package test;
import java.io.*;
import java.util.*;
import javax.servlet.*;
public class TimeFilter implements Filter {
  public void init(FilterConfig config) throws ServletException {
  public void doFilter(ServletRequest request, ServletResponse response,
    FilterChain chain) throws IOException, ServletException {
    int hour = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);
    // only service the request between 08:00 and 17:59
    if (hour >= 8 && hour <= 17) {
      chain.doFilter(request, response);
    // for other times, forward the request to someplaceelse
    } else {
      request.getRequestDispatcher("/someplaceelse").forward(request, response);
  public void destroy() {
}You will also need this in your web.xml :
<filter>
  <filter-name>TimeFilter</filter-name>
  <filter-class>test.TimeFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>TimeFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
