Answer 1

File name cannot be directly retrieved. You can use Apache Commons Fileupload API -

// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();

// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);

// Parse the request
List /* FileItem */ items = upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
    FileItem item = (FileItem) iter.next();

    if (item.isFormField()) {
       // Process a normal field
       String name = item.getFieldName();
       String value = item.getString();

    } else {
        // Process a file upload field 
    String fileName = item.getName();
    // DO further processing

    }
}

It can also be done with just Java but obviously more code will be required.
