So, setting "struts.i18n.encoding=UTF8" in struts.properties doesn't
work? Do you know how the "Inject" annotation works? I certainly don't.
Are you sure that's not a system property (instead of a property loaded
from a file)?

I agree. It seems like S2 includes the capability of fixing the request
encoding (and should do the same thing as the CharacterEncodingFilter).
Perhaps it's just not configured properly.

I would bet that Firefox is better about reporting the encoding of the
request, and it's sending "UTF8" as part of the encoding header. MSIE
might just be assuming that since the server sent the (previous)
response as UTF-8, that the server will expect UTF-8 in the (next)
request, so it doesn't bother to mention it. That's just a wild guess.
The inconsistency of browsers and servers with regard to character
encoding of requests and URLs is shocking. :(

Re: [S2] Chinese encoding problem
Chris,
Thank you.
I solved this problem finally.
I use a CharacterEncodingFilter you mentioned to set character encoding to
UTF-8.
Actually I've tried this filter before, but it didn't work.
The reason why it didn't work is the order of fitler mapping is incorrect in
my web.xml.
This filter must be in front of struts 2 filter like this:
SetCharacterEncoding
/*
struts2
/*
But it sitll strange that I've traced the struts 2.0.6 source code and found
that id does change the encoding of HttpServletRequest in
Dispatcher.java(line 650):
public void prepare(HttpServletRequest request, HttpServletResponse
response) {
String encoding = null;
if (defaultEncoding != null) {
encoding = defaultEncoding;
}
Locale locale = null;
if (defaultLocale != null) {
locale = LocalizedTextUtil.localeFromString(defaultLocale,
request.getLocale());
}
if (encoding != null) {
try {
request.setCharacterEncoding(encoding);
} catch (Exception e) {
LOG.error("Error setting character encoding to '" + encoding
+ "' - ignoring.", e);
}
}
if (locale != null) {
response.setLocale(locale);
}
if (paramsWorkaroundEnabled) {
request.getParameter("foo"); // simply read any parameter
(existing or not) to "prime" the request
}
}
And there is a setDefaultEncoding() method in line 227:
@Inject(value=StrutsConstants.STRUTS_LOCALE, required=false)
public static void setDefaultLocale(String val) {
defaultLocale = val;
}
It seems to get encoding parameter from struts.propertes with key
struts.i18n.encoding in struts.properties file.
But somehow it doesn't work in my app.
The filter has solved this problem. But I think in struts 2, we shouldn't do
this filter?
It makes the code a bit ugly.
The behaviors in IE and Firefox are different really confuses me.
Why the browser affect the character encoding in HttpServletRequest?

:(
You mentioned that MSIE seems to fail, while Mozilla Firefox works. Is
this behavior consistent? Does ff always work? Does MSIE always fail?
Can you check to see what character encoding (in the HTTP headers) is
being sent from the client when things work? What about the failure
situation?
It's possible that MSIE is not sending the correct request encoding (or,
more likely,not sending it at all). If you know your clients will (or
should) be sending UTF-8 all the time, you could use the
CharacterEncodingFilter mentioned on this list several times to simply
override the default encoding used when the browser sends no encoding
(or override it unconditionally). This might work.

Re: [S2] Chinese encoding problem
But why does it works in Firefox while it doesn't work in IE?
I think it might be caused by different http request header made by IE and
Firefox.
There might be an Interceptor or servlet filter in struts2 which change the
character encoding according to the header of http request.

Emilia,
I've tried -Dclient.encoding.override=UTF-8, it doesn't seem to change
anything.
It's really wired that when I use IE, the Chinese characters will be
scramble.
But when I use firefox, it works correctly.
The funny thing is that the browser language setting of my IE is "zh_TW"
while the setting in firefox is "en".
Is there any interceptor in S2 changing the encoding of request?
