I have no clue what your error is, but it's so much easier to read files
with HTML5 now.
Something like this:
-----
<input ui:field="fileInput" style="display: none;" type="file" />
@UiField InputElement fileInput;
Event.sinkEvents(fileInput, Event.ONCHANGE);
Event.setEventListener(fileInput, event -> handleFileUpload());
private void handleFileUpload() {
JavaScriptObject files = fileInput.getPropertyJSO("files");
if (files instanceof JsArray) {
JsArray<JavaScriptObject> filesArray =
(JsArray<JavaScriptObject>)files;
if (filesArray.length() > 0) {
handleFileUploadJS(filesArray.get(0), fileData ->
handleAfterFileUpload(fileData));
}
}
}
private static native void handleFileUploadJS(JavaScriptObject fileData)
/*-{
var fileReader = new FileReader();
fileReader.addEventListener("load", function () {
// Your file data will be in fileReader.result
}, false);
fileReader.readAsDataURL(fileData);
}-*/;
-----
No server code needed. :)
