For the moment I have written a filter, which sets a default encoding,
as
soon as Response.setContentType(String type) is called and
type.startsWith("text/"). That works for the moment, but I would prefer
the
solution described in above thread.
I know that setting charset in a mime-mapping works, e.g.:
<mime-mapping>
<extension>htm</extension>
<mime-type>text/html;charset=iso-8859-1</mime-type>
</mime-mapping>
<mime-mapping>
<extension>html</extension>
<mime-type>text/html;charset=iso-8859-1</mime-type>
</mime-mapping>
Note, that it would be better if the mime type set by a HTTP header
and the one provided by HTML tag match strictly (case sensitively).
Otherwise some browsers will start guessing. IIRC, the HTML spec says
that the HTTP header takes precedence, but not all browsers follow it
strictly.
I will look into this one.
Also there is AddDefaultCharsetFilter in Tomcat 7. It is similar to
what you are doing, see its JavaDoc and source code.
Yes, my filter looked like a twin, with the exception, that I called
super.setCharacterEncoding(defaultEncoding) instead of manipulating the
content-type directly (and of course that defaultEncoding is different to
super.getCharacterEncoding() which would yield iso-8859-1).
I could extend that filter to my needs. Should I file a enhancement
request for that?
apache httpd thinks it would be better to append a
charset to the response
I wonder, if there is a way to improve your Apache HTTPD configuration.
I tried to let apache httpd now that in location /webapp the default
charset was different from iso-8859-1. But mod_jk ignored my pledges :(
Even so I think DefaultServlet should be able to set a charset if
configured to.
How did you do that in Apache? Did you use
http://httpd.apache.org/docs/2.2/mod/core.html#adddefaultcharset
and if so, how exactly?
You can switch JkLogLevel on a system with low load to "debug", then
mod_jk will log all response headers it received from Tomcat.
mod_jk itself takes the Content-Type header received from tomcat,
extracts its full value and applies it to the Apache response via
ap_set_content_type(). Apache later applies any configured default
charset via ap_http_header_filter() in ap_http_header_filter(). At least
that's what I expect to happen.
