File upload

A more efficient and simple upload method has evolved in Java EE 7. Now, we can upload files through our web forms with little code. In this section, we will see a very practical sample. Now, let's start creating an upload form through a JSP page:

   <input type="file" name="file" size="50" /> <br /> 
   <inputtype="submit" value="Upload File" />
</form>

To send the file to the server, we need to configure the form with a particular enc type, the multipart/form-data. It is the standard mode used to send the files. Here's a list of the available enc types of the forms:
