RE: Q:how to remove charset from HTTP responce to allow browser use a browser selected charset?
Hi Rick,
Yes my data comes from different locales I should say it's a legacy
data. I have no ability co convert it to UTF-8 right now.
response.setContentType("text/html;charset=..."); mess up the not
UTF-8 output, I'm getting ???s instead of a valid data.
I think I'll go with request.setCharacterEncoding(encoding);
Crossing my fingers...
Mark.

Other Mark's answer was a little incomplete. If your Servlet uses
response.getWriter, then the spec requires that you get a charset on the
Response headers. If your Servlet doesn't specify a charset in the
response.setContentType, then a Filter something like:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws ServletException, IOException {
if(request instanceof HttpServletRequest) {
HttpServletRequest hreq = (HttpServletRequest)request;
HttpSession session = hreq.getSession();
String enc = (String)session.getAttribute(MY_ENC_ATTR_NAME);
if(enc == null) {
enc = getCharSetForUser(hreq); // Your lookup from DB
function
if(enc != null) {
session.setAttribute(MY_ENC_ATTR_NAME, enc);
}
}
if(enc != null) {
response.setCharacterEncoding(enc);
}
}
chain.doFilter(request, response);
}

RE: Q:how to remove charset from HTTP responce to allow browser use a browser selected charset?
Hi Mark,
Can you talk a little about what the data is.. Just form data from
different locales?
I store all my data in UTF-8 and just instruct the page encoding to be the
same (UTF-8) and I'm able to handle input and display of whatever people
enter. Had a few odd things to overcome to get it working like,
JSP: I had to save the actual JSP file in UTF8 otherwise I couldn't get it
to serve the page with UTF8 properly.. This started after Tomcat 5.0.16 or
something like that.
Servlet: don't think I had to do anything wild.. Just set the charset before
you do anything with the output stream, including just getting a handle to
the stream writer. Set the contenttype first.
response.setContentType("text/html;charset=UTF-8");
Depending on what you are reading from and such. You may also want to set
some Java ARGs when starting Tomcat... Like:
-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8
-DjavaEncoding=UTF-8
Not sure if this is relevant, but hope it helps,
Rick

Hi Mark,
In my case servlet generates an output, so no JSP for now...
Can I do it using filters? Or define and store user's prefs with encoding
outside of tomcat and in the session and use if it's exists in the session?
Thanks a lot!

Mark wrote: Hello, In my application users enter data using different languages. The problem I'm facing is the browser sets the page encoding always to ISO-8859-1. (I guess this is default based on server OS) User can change encoding on the page (Browser settings) and everything looks OK but only for one page. On the next page encoding is back to ISO-8859-1. Is there any way to instruct tomcat not to send the page encoding? If you are using JSPs, no. The spec requires that the charset is set.
