In my understanding, a filter is the reccomended method of handling UTF-8 for both GET & POST (as well as other methods like HEAD, PUT etc.). When the request is "test.jsp?Name=larevolu%C8%9Bie" as in the example page the EncodingFilter.doFilter function is being called and it calls the EncodingFilter.check function as below Name=request.getParameter("Name"); if (Name!=null) check(Name, lang); and the String Name is incorrect as mentionned in the comment below: void check(String Name, java.util.Locale lang) { int c8=Name.codePointAt(8);//c8=200=C8 // should be 539=21Bh = ț int c9=Name.codePointAt(9);//c9=155=9B // should be 105= 69h = i char ch[]={Name.charAt(8),Name.charAt(9)}; int x=c8+c9; //to have eclipse (Galileo) display the above String s=new String(ch); } server.xml contains the following: <Connector port="8060" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" /> This is because my tomcat 6 is set to work on 8060 with no redirect because this is a debug setting. (some time ago I also had tomcat 5 on 8050 but at that time I didn't check the UTF-8 issue) Thanks for you help.

Have you check the documentation on the conf/server.xml on the following line? <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/> -Ake From: Mircea LUTIC [mailto:mircea_lu...@yahoo.com] Sent: Wednesday, April 21, 2010 3:40 PM To: users@tomcat.apache.org Subject: UTF-8 encoding in Tomcat 6.0 Hello, I'm having trouble convincing tomcat 6.0 to take UTF-8 strings.
