I'm looking for specific code on how to send a file from the server-side of a GWT application so that the client-side user can save it on his machine. Currently, the app allows the user to upload a file, reads it, and puts certain values from the file into editable text boxes. When the user hits the "save as" button, it collects that edited data, puts it back into the file string, and sends that string to the server, where I want it to be put into a file and pushed back to the user on the client side, so that they can save it to their machine. How exactly do I accomplish that?
Sorry if this seems like an obvious thing, but I'm relatively new to GWT and java in general. Thanks!
