Websphere 4.0.5, java.io.UnsupportedEncodingException: Cp1386
Anony
We are using IBM Websphere Application Server 4.0.5 on HP-UX
When a web browser sends an HTTP request to an HTTP server,
the request contains an "Accept-Language" header.
Accept-Language may contain one or more languages.
Within the United States, browsers used by English-speaking users will
usually send:
Accept-Language: en
or
Accept-Language: en-us
or
Accept-Language: en-us, en
Websphere 4.0.5 gets into trouble when the user's preferred language is
Chinese. Websphere 4.0.5 will choke if it encounters this header in
an HTTP request:
Accept-Language: zh-cn, en-us
How to reproduce this bug:
1) launch Internet Explorer
2) select "Tools"
3) select "Internet Options"
4) press the "Languages" button
5) click "Add..."
6) select "Chinese (China) [zh-cn]"
7) press OK
8) select "Chinese (China) [zh-cn]"
9) press "Move Up"
10) press OK
11) press OK
12) visit http://foobar/yummy/
13) Try to login to the site
It might (?) be possible to workaround this issue by editing a
Websphere property file:
$WAS4HOME/properties/converter.properties
We've escalated this issue to IBM's technical support.
