Java EE (Java Enterprise Edition) General Discussion

Hi,

I wanna automatically refresh my jsp age in every 5 minutes.I included this header response for the same.

response.setHeader("Refresh", "50; URL=MyJspPage.jsp");
response.setHeader("Cache-Control","must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "public");

But in the second time, the page won't get the requests so that my page will be null after every refreshment.

Pls Give me some tips on this regard,urgently

Thanks for ur time
