The answer is the same, you need to use something like gwt-upload to get the files from the user/client to your server. Once this gets the file onto your server, you can process it however you want, with another service or anything.
You cannot use RPC to do this because your client has no direct access to the files on the user's machine - and for good security reasons! -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
