One way you can set the refresh header which auto checks for every 5 secs or 10 etc and displays the new data. This way once the data is fully there then do not set the refresh header and just send the data in your servlet. This way part of the servlet result can be displayed and rest as and when it comes.
Thanks and Regards,

Is that a bad thing?
That is, when you're off working on something else, is the page finished or
isn't it?
If it is finished, you can close the output stream, and do the work in
another thread. If it isn't finished (i.e., if the work you're doing has to
return to the browser's page), then the browser _should_ seem busy, because
it's waiting on more data.
(Any other solution to this, including launching more browser windows or
refreshing the page constantly for extra data, will be solved with
HTML/HTTP, and won't be specific to Tomcat, to servlets, or even to any Java
code. You can try looking around HTML web sites, like html.about.com or
www.webdeveloper.com .)
