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. --- Rick [EMAIL PROTECTED] wrote: Hi Mark, Can you talk a little about what the data is..

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?
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);
}
Thanks a lot!
Mark.

If you are using JSPs, no. The spec requires that the charset is
set.
