The change you're referring to was done in order to address 4867842
("I18n DTD inconsistencies between WebServer 6.1 and 8.0").
WS 6.1 had deprecated <locale-charset-info> (and its
<locale-charset-map> subelement) for these valid reasons:
- <locale-charset-info> maps request locales (obtained by
a call to ServletRequest.getLocale()) to their encodings,
using its <locale-charset-map> subelement.
The container is supposed to pass the mapped-to encoding
to ServletRequest.setCharacterEncoding().
This is wrong, because ServletRequest.getLocale() returns the
value of the "Accept-Language" request header, which must not be
used to set the request encoding: it is supposed to be used to
negotiate the *response* locale and encoding!
- Servlet 2.4 added the <locale-encoding-mapping-list> element to the
deployment descriptor, which maps a (response) locale to its encoding.
As a result of this, <locale-charset-map> was no longer needed.
Since <parameter-encoding> used to be a subelement of the now deprecated
<locale-charset-info>, but was still useful, it was promoted to become
a direct child of <sun-web-app>.
The <parameter-encoding> subelement of <sun-web-app> takes precedence
over the <parameter-encoding> subelement of the deprecated
<locale-charset-info>.
These changes were propagated to AS 8.0, in order to align with WS.
