how to avoid blinking of page when it refreshes

hai,
i am refreshing a jsp page every second to read the updated data form javascript.when i am doing it,i can see the blinking.is there any method to refresh the page without the effect of bliking.
bye

If you are totally re-writing the page it is going to blink. The alternative would be using JavaScript to retrieve data to an invisible document and then transfer the contents to your visible page using the Document Object Model.
Thats really a JavaScript question, not a JSP one.

Urg - all the examples I have are huge and proprietary. If you are going to work in this area, you might as well get a Javascript book - a nice cheap one I like is JavaScript for the World Wide Web published by Peachpit press. You might also ask on the Javascript forum here.
