sendRedirect after time interval avoiding javascript or php

How can I do the following

response.sendRedirect("index.jsp");

after a certain time interval from another jsp without using javascript or php?

The idea is to show an error in a "error_page.jsp" and then after some time automatically redirect the user to the index page. Thanks in advance.

Refresh HTTP header is supposed to control timed redirects.

You can set it in HTML, by adding to your error_page.jsp this meta tag:

<meta http-equiv="Refresh" content="5;url=next_page.jsp">

(5 stands for 5 seconds before next_page.jsp gets loaded)

You would most probably pass the name of the next page as a parameter to the JSP, or a request attribute, so that instead of next_page.jsp it would be ${param.nextPage} or just ${nextPage} respectively.

And of course you can set the same header from servlet: response.setHeader("Refresh", "5;url=next_page.jsp");.

You could even put this code inside JSP <% response.setHeader("Refresh", "5;url=next_page.jsp"); %>.
