I have a web application runs in websphere. It has a massive calculation engine. So when i call that calculation from the front-end(jsp) it takes sevral seconds to complete the calculation. At this point i want to show some message with a gif(a clock ticking). So when i submit the page for calculation i call a jsp with the message and gif. And onload of the page i am calling the calculation. At the end of the calculation i call some other jsp. Now the problem is, gif loaded in the intermediate jsp is not animating(clock is not ticking). I have seen in some web pages when you do a search they display some gif-animation until they are ready with the results. How to do this?

assuming your animationiss in frame "haut2"
in your main frame, in client script yu intercep the action which generate the calculation and add this script before to navigate to the calculation form:

set wdoc=parent.frames("haut2").document
for each element in wdoc.all
if element.tagname="IMG"  then
element.style.visibility="visible"
end if
window.navigate dest(where you perform the calculation)
next

in the window onload event of your main frame, activated when you send the calculation results, you add the same script with :visibility="hidden"
in my case i use IIS and ASP,the image is a gif animated and it' s working fine.The animation is done on client side and the calculation on the server.you need frames to do it.

regards
