------------------------------------------
Dear Jochen,
Last question I promise,
Yeah I was thinking about that but I was confused about two things:
replacing this line response.getWriter().write(new String(uploadItem.get()));
with
1) response.getOutputStream().println(new String(uploadItem.get()));
(with no carriage return-line feed (CRLF) at the end.)
or
2) response.getOutputStream().print(new String(uploadItem.get()));
(Writes a String to the client, followed by a carriage return-line feed
(CRLF).)
what is a carriage return-line feed(CRLF)?
My input data is like this,i.e:
1 2 "305 Memorial Drive Cambridge, Ma,02139"
3 4 "77 Massachusetts Ave, Cambridge MA, 02139"
and I want my output to look like:
1 2 "305 Memorial Drive Cambridge, Ma,02139"
3 4 "77 Massachusetts Ave, Cambridge MA, 02139"
well at the end I am going to change the output, this is just to see how it
works. I wasn't sure what the difference is bet. print and println or what is
CRLF.
Your attention to this matter is highly appreciated.
Sincerely,
Barry Barrios

> I am using response.getWriter().write(new String(uploadItem.get() to write
> the uploaded input file. The code works pretty well except the output is very
> disorganized. I want the output to look exactly the same as the input file,
