servlet printing unicode
[nobr]i am just trying to print a set of turkish charcters for test purposes. following code throws an exception thats where i am checking if characters are printed correctly. even thoug i set the content-type to utf-8 tomcat doesn't set it i get the following as my headers. i also tried some other encodings just to check if it changes to another value with no luck. am i missing something?

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

Boolean validQuery = parseQuery( request );
printHeader( );
if ( validQuery ==false ){
out.println("<br>Invalid Query.. "
);
return;
}
finallong start = System.currentTimeMillis();
searchResult = service.doSearch(query , resultBegin , resultEnd );
String timeTook =Long.toString
( System.currentTimeMillis() - start );
printResults( timeTook );
//print footer
printFooter( );
}catch(Exception e){
out.println("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=ISO-8859-9\">");
out.println("\u0130\u0131\u00D6\u00F6\u00DC\u00FC\u00C7\u00E7\u0aaE\u011F\u015E\u015F");
out.println( e );
return;
}
}

Using apache-tomcat-5.5.20.
I have just modified one of my servlets to display your Turkish string. If I useString encoding= "utf-8";
res.setContentType("text/html;charset=" + encoding);
res.setCharacterEncoding(encoding);
then I get the string displayed correctly. If I change the encoding to "iso-8859-9" then one character '\u00E7' is not displayed correctly but all the rest are.
P.S. I hope this code is not going into production because 'out', 'service' and 'searchResult' seem to be declared as servlet instance variables which makes the servlet not thread safe.

did your http header changed if i change text/html to text/xml or text/cvs contentType header change but charset is still set to iso8859-1 is there a hard coded value in tomcat that overrides mine?

that comes from my misunderstanding of servlets i thougth every client gets a fresh copy of the class just like running from command line. i was having concurency issues thanks for pointing out.
i check it using a firefox plug in ( live http headers ) here is the full http transaction..
