thanks help

you have upload file server.

the easiest way in gwt put fileupload (and form input widgets) in formpanel; has drawback of making error handling (and response handling server) more difficult though.

an alternative, in recent browsers, file object (not java.io.file, js object) out of fileupload , upload using xmlhttprequest (possibly coupled formdata send other form values). in gwt, means using jsni (it might possible use elemental library too), , know innards of you're doing.

in case, won't able use gwt-rpc talk server and send file @ same time.
