Also, my application will eventually be put on a web- based hosting provider and I may not have access to the server.xml file. What I want is my application to be fully UTF-8 based regardless of what the server is configured like. The request javax.servlet.Filter system which is configured in the web.xml file seems to be the way to do it.

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.
