Java Servlet Repsonse Set Content Lenght For CSV

Question

Requirements

Downlading a CSV File

Code

I have a csvFormattedString like

String csvFormattedString = "\"Column_One\",\"Column_Two\"\n\"Row_Col1\",\"Row_Col2\"\n";

This CSV String is written to the reponse print writer using

response.getWriter().write(csvFormattedString);

I have set the headers as application-force-download and have set the charcter encoding to UTF-8.

I would like to send the response length back to the user as well.

The csvFormattedString.length() does not seem to be correct as some my characters get truncated

I am using no library to create the csv string, if you mean to ask that — Anand Sunderraman, Mar 19 '13 at 13:14
I mean, what is the class of response object? How did you send this to the client? What's the class of the response rappresentation on the clientSide? — Alepac, Mar 19 '13 at 13:22

csvFormattedString.length() counts the characters. Use s.getBytes("UTF-8").length to get the number of bytes used for that string represented as UTF-8.

You have to catch UnsupportedEncodingException in order to use getBytes(String encoding).
