Hi Mircea,

=20

That filter you wrote is for POST and it has nothing to do with GET =
request.

=20

Have you check the documentation on the conf/server.xml on the following =
line?

    <Connector port=3D"8080" protocol=3D"HTTP/1.1"=20

               connectionTimeout=3D"20000"=20

               redirectPort=3D"8443" URIEncoding=3D"UTF-8"/>

Subject: UTF-8 encoding in Tomcat 6.0

=20

Hello,


I'm having trouble convincing tomcat 6.0 to take UTF-8 strings.
I created an encoding filter with no luck.=20

/**
    Here is the Utf8 Filter that fails for me in=20
Tomcat 6.0.20 / Eclipse-Galileo / Windows Vista (6.0.6002) <---> Firefox =
3.6.3.
        java version "1.6.0_20"
        Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
        Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode)
    Everything is on my  laptop (http://localhost:8060).
   =20
    What I do is create a GET string (based on parameters from a =
showModalDialog)
    by script and send it (from Firefox) to the (localhost) server=20
    which is running under eclipse with a breakpoint in the =
EncodingFilter.

    Note that the system locale is ro_RO (may have an influence)
