- AutoRefresh a webpage
To autorefresh a web page after a some time,you just need to set the response header with two parameters.In first parameter we specify refresh as string and in second parameter the seconds after which page is to be refreshed and url of web page where the page should redirect after refresh.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class AutoRefreshServlet extends HttpServlet
{
int i=0;
public void service(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
{
try
{
response.setContentType("text/html");
response.setHeader("refresh","2;URL=http://www.facebook.com");
PrintWriter out=response.getWriter();
out.println("<html><body bgcolor=red>");
//out.println("this is auto refresh page:"+(++i));
out.println("<a href=http://www.google.com>google</a>");
out.println("<a href=http://www.facebook.com>facebook</a>");
out.println("</body></html>");
out.close();
}
catch(Exception e){System.out.println(e);}
}
}
