How can you retrieve the data sent by the FORM displayed by following HTML page code?

Code

<html>

<body>

<form action="/myapp/SaveServlet" method="POST">

<input type="file" name="name">

<input type="submit" value="POST">

</form>

</body>

</html>

Options

Select 2 correct options.

1 request.getParameter("name");

2 request.getAttribute("name");

3 request.getInputStream();

4 request.getReader();
The answers are 3 & 4. I thought the answer is only 1. Anyone can explain?

Hi dolly !!!

A request's parameter is a pair String/String.
request.getParameter("name"); will return you a String

Here name is a File you cannot get it with the method getParameter().

You have two posibilities:

Retrieve the body as character data using BufferedReader with the method getReader().

(public BufferedReader getReader() throws IOException )

Retrieve the body of the request as binary data using ServletInputStream with getInputStream().

(public ServletInputStream getInputStream() throws IOException )
Hope It help.
