Recursive Directory Upload

Support
#1

I want to recursively upload files from a directory and then additionally evaluate the original path. The HTMLInputElement multiple webkitdirectory provides exactly what I need. I also managed to integrate the HTMLInputElement into a javascript component. But I do not know how to access the server side file object.
Can someone help me there? Or is there perhaps an easier way?

Hi,

Probably, you can use Vaadin request handler for the current HTTP session: Request Handlers | Advanced Topics | Framework | Vaadin 7 Docs

VaadinSession.getCurrent().addRequestHandler(
        new RequestHandler() {
    @Override
    public boolean handleRequest(VaadinSession session,
                                 VaadinRequest request,
                                 VaadinResponse response)
            throws IOException {
        if ("/rhexample".equals(request.getPathInfo())) {
            // Generate a plain text document
            response.setContentType("text/plain");
            response.getWriter().append(
               "Here's some dynamically generated content.\n");
            response.getWriter().format(Locale.ENGLISH,
               "Time: %Tc\n", new Date());

            // Use shared session data
            response.getWriter().format("Session data: %s\n",
                session.getAttribute("mydata"));

            return true; // We wrote a response
        } else
            return false; // No response was written
    }
});

Add this request handler from Vaadin component code and you will be able to handle multipart uploads to /rhexample URL.
