    <section name="Using FileUpload">
      <p>
        Your application should detect whether or not FileUpload should be
        invoked, based on the HTTP method and the content type of the request.
      </p>
      <p>
        Assuming that you have decided that FileUpload should be invoked, you
        might write the following code to handle a file upload request:
<pre>
    // Create a new file upload handler
    DiskFileUpload upload = new DiskFileUpload();

    // Set upload parameters
    upload.setSizeMax(MAX_UPLOAD_SIZE);
    upload.setSizeThreshold(MAX_MEMORY_SIZE);
    upload.setRepositoryPath(TEMP_DIR);

    // Parse the request
    List items = upload.parseRequest(request);

    // Process the uploaded fields
    Iterator iter = items.iterator();
    while (iter.hasNext()) {
        FileItem item = (FileItem) iter.next();

        if (item.isFormField()) {
            processTextParameter(request, item);
        } else {
            processFileParameter(request, item);
        }
    }
</pre>
      </p>
    </section>
