Setting up gwtupload with uiBinder

I'm trying to setup the gwtupload widget with uiBinder and I'm having a hard time getting this configured.

I got the code working with the regular gwt-fileUpload widget, but I wanted the gwtupload because of it's richer functionality. Here is what I did for the gwt-fileUpload widget:

    @UiHandler("calculateComplexityButton")
    void onClickCalculateComplexity(ClickEvent e){
        formPanel.setEncoding(FormPanel.ENCODING_MULTIPART);
        formPanel.setMethod(FormPanel.METHOD_POST);
        formPanel.setAction(UPLOAD_ACTION_URL);
        String fileName = fileUpload.getFilename();
        fileUpload.setName(fileName);
        formPanel.submit();
    }

I'm not seeing how to setup the same thing with gwtupload. I'm seeing this error: 

HTTP ERROR: 404 NOT_FOUND
RequestURI=/servlet.gupld

I don't understand how to map the gwtupload widget to my servletPath, because I'm configuring it under uiBinder?

Solution

  • In order to set the servletPath, you must first

    1. Set up a custom ui namespace, ie I used "up" below:

    2. Define the servletPath in the widget definition itself.

      <up:MultiUploader type="LABEL" ui:field="uploader" 
  servletPath="/...     /SampleUploadServlet" 
  styleName="{style.myup}" maximumFiles="2" 
  avoidRepeatFiles="true"   validExtensions="xml"/>
