RE: character encoding in HTTP GET / POST requests
Suppose I would migrate to Tomcat 3.3, would changing the defaultEncoding of the DecodeInterceptor in the server.xml file do the trick for me? See: http://jakarta.apache.org/tomcat/tomcat-3.3-doc/serverxml.html#DecodeInterce ptor But how can I do the same in Tomcat 4.0? thx, Nico Hoogervorst Compuware -Original Message- From: Hoogervorst, Nico [mailto:[EMAIL PROTECTED]] Sent: Monday, November 26, 2001 5:44 PM To: '[EMAIL PROTECTED]' Subject: character encoding in HTTP GET / POST requests Hi there, About: HTTP GET/POST request in UTF-8 with Tomcat 3.2, Apache webserver, struts-framework To be able to display foreign characters, we want to use unicode.

RE: character encoding in HTTP GET / POST requests
I keep answering my own questions. :-) In Tomcat 4.0 the trick is to create a filter, which sets the CharacterEncoding, like explained in: http://java.sun.com/products/servlet/Filters.html#72673 And then, add the filter in the web.xml, like this: web-app !-- Filter to set character encoding on each request -- filter filter-nameSet Character Encoding/filter-name filter-classfilters.SetCharacterEncodingFilter/filter-class init-param param-nameencoding/param-name param-valueUTF-8/param-value /init-param /filter -Original Message- From: Hoogervorst, Nico [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 27, 2001 3:27 PM To: 'Tomcat Users List' Subject: RE: character encoding in HTTP GET / POST requests Suppose I would migrate to Tomcat 3.3, would changing the defaultEncoding of the DecodeInterceptor in the server.xml file do the trick for me?
