Tomcat Servlet FileUpload和UTF-8

Question

I am using commons FileUpload to get client headers. I am trying to use the header Strings to write txt content like:

StringA; StringB; "ciryllic word"

The server localization is ru_RU.utf-8 the client is cp1251... The result is I always get on my client (desktop app)

StringA; StringB; ?????

instead of cyrillic characters in my server txt files lines. If I open txt with my IE 8 and watch the encoding the cyrillic content can be readable with utf-8 encoding only :( So my question is what should me do to make my servlet write ru_RU.utf-8 acceptable strings. I am testing it on windows so I need to know it for sure

Please help me to understand

Any useful comment is appreciated

Answer 1

ServletOutputStream out =response.getOutputStream();
out.write((YOUrfileasstring).getBytes("UTF-8"));

Answer 2

I might be misunderstanding the question, but to answer this part -

So my question is what should me do to make my servlet write ru_RU.utf-8 acceptable strings.

You should use either of two methods provided by the HttpServletResponse class. Those are:

setContentType(), eg

    response.setContentType("text/html; charset=UTF-8");

or,

setCharacterEncoding(), eg

    response.setCharacterEncoding("utf-8");

There are other examples for those methods and information on when to use them all over the place.
