Problem with GWT Image Upload in my Touchkit app

Flow
1

Hi, I’m developing a mobile app using TouchKit that allows the user to take pictures with his mobile, but I can’t make it work. Firstly, when I include the GWT Image Upload addon to WEB-INF/lib folder and then I try to use the ImageUpload component I get this message in line 9:
“The type org.vectomatic.file.FileUploadExt cannot be resolved. It is indirectly referenced from required .class files”.

[code]
final ImageUpload fileUpload = new ImageUpload();
fileUpload.setCapture(true);

    // Normalize the orientation and make size suitable for
    // sending to server
    EXIFOrientationNormalizer normalizer = new EXIFOrientationNormalizer();
    normalizer.setMaxWidth(1024);
    normalizer.setMaxHeight(1024);



fileUpload.addImageManipulator(normalizer);


fileUpload.addImageLoadedHandler(new ImageLoadedHandler() {
@Override
public void onImageLoaded(ImageLoadedEvent event) {
// Store the image data as encoded URL
setImage(event.getImageData().getDataURL());
}
});

    // Reduce the size further for displaying a thumbnail
    ImageTransformer thumbGenerator = new ImageTransformer();
    thumbGenerator.setImageDataSource(fileUpload);
    thumbGenerator.setMaxWidth(75);
    thumbGenerator.setMaxHeight(75);
    thumbGenerator.addImageLoadedHandler(new ImageLoadedHandler() {
       @Override
       public void onImageLoaded(ImageLoadedEvent event) {
           // Store the thumbnail image data as encoded URL

// setThumbnail(event.getImageData().getDataURL());
}
});

    Button image_Button = new Button();
    image_Button.addClickListener(new ClickListener(){
        @Override
        public void buttonClick(ClickEvent event) {
            // TODO Auto-generated method stub
            fileUpload.click();
        }
    });

[/code]If I download the GWT-File libraries and add them to my lib the message dissapears but when I run the application I get the
“Widgetset does not contain implementation for ImageUpload…”
message.

Secondly, if I include the TouchKit addon and the GWT Image upload addon in the ivy.xml file and not in the WEB-INF/lib folder I get a different error when I run the application:
"

com.vaadin.server.ServiceException: java.lang.NoClassDefFoundError: com/google/gwt/user/client/ui/HasName"

Does anybody know what’s going on here? Any help will be appreciated,
Thanks in advance,
