Hi, I would like to simulate a waiting screen using servlets. When a user clicks on a button I excecute following:
The servlet will 1) Send a reponse back to the 'calculating' window indicating the user has to wait. 2) Starts up a Thread that performs the calculation (well in fact, it is generating a .pdf document). Now my problems are following: 1) When the generation is finished I need to close the waiting screen and 2) The .pdf needs to send back to the main window. I don't have any idea how to do this. Any suggestions ? Thanks , Stefan
