Need help on JSP

Hi, I need to achieve the following. I am creating a JSP page that should retrieve data from the database. The JSP page should refresh every 2 minutes. The data should be displayed in the form of a table with the title of the columns on the JSP page hyperlinked. When user clicks on a column title, the data should be sorted in an ascending or descending order.

I have written a servlet that fetches the data and forwards it to the jsp page. Also, when the user clicks on the column title, the servlet is called with some parameters in the query string and it sorts the data and forwards it to the JSP page. I am not using <FORM> tag in the JSP page as I do not have to submit anything from the JSP page to the servlet. Now the question on refreshing the JSP page. I can use the <META HTTP-EQUIV = "Refresh" ....> tag in the JSP page, but how can I send parameters to the servlet through this tag? I understand that a GET request will be sent with this refresh tag. Is that correct?

Also, it would be great if you could suggest any better way to achieve what I am trying to do in the above mentioned application.
