One way to do this is: 1. Start a thread on your search action that does the actual retrieval and processing of the data. At the end of the thread's execution, place a flag in the session that you will check for later on to see if the search/processing is done. 2. Right after starting the thread, forward immediately to your "Please wait" page. 3. On your "please wait" page, use javascript setTimeout() to submit an empty form to an action every, say, 1500ms. 4. On your action, check for the flag in the session. If it's present, remove the flag and forward to your result page; otherwise, forward again to the processing page.
