Hi, the use case here is for report generation. I would like to be able to submit a GWT form to a servlet that will generate the report, and upon form submission, pop-up a new browser window containing the PDF report in it.
I have read that the easiest way to do this is to POST the form to the servlet, generate the report, put the report into the user's HttpSession, return a token that identifies the report in the session back to the client, and then open a pop-up window issuing a GET request with the token. However this approach would require me to perform session cleanup as generating a lot of reports can bloat one's session. I would prefer to be able to (1) pop-up a window (maybe display a "Loading..." message), (2) POST the form to the servlet, and (3) on the callback of this request, change the content of the window to display the response from the request. Is this at all possible?? I can't figure out how to do step (3). -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
