How can you retrieve the data sent by the FORM displayed by following HTML page code?
<html>
<body>
<form action="/myapp/SaveServlet" method="POST">
<input type="file" name="name">
<input type="submit" value="POST">
</form>
</body>
</html>
1)request.getParameter("name");
2)request.getAttribute("name");
3)request.getInputStream();
4)request.getReader();
5)request.getFileInputStream();
The correct answer given is 3 and 5. I agree.
But why the answer given 1 is wrong, because there is a parameter name in the html.
This is from Enthuware.
Please advise.

1. In the given example html input "type" is "file" and not "text".
2. getParameter() returns you a String.
3. Being we are tring to access the file request object, we will not get String. Hence this answer is wrong.
Thanks,

The getFileInputStream()? Such a method doesn't exist in the HttpServletRequest and in the ServletRequest API. Where did you find it?

The answer should be 3 and 4...we can use both InputStream getInputStream() and BufferedReader getReader()
