PI82529: HTTP transport encoding CP943C will be used for jstl params

Fixes are available

APAR status

Closed as program error.

Error description

WAS provides default Shift_JIS=Cp943C converter.properties
file
to map a Java code set to a IANA charset. Same Cp943C
encoding
method is not honored for JSTL params.
----------------------------
Issue:
<% @ Page contentType = "text / html; charset = Cp943C"
pageEncoding =
"Cp943C" language = "java"%>
---
The above method can not be applied.
Garbled characters do not occur, but "Cp943C" can not be
used
with HTTP because it is not registered with IANA.

---
<% @ Page contentType = "text / html; charset = windows -
31J"
pageEncoding = "Cp943C" language = "java"%>
---
The above method can not be applied.

Since the database uses the character code of Cp943C, a
difference will be generated

Local fix

Based on the current concerns with the IANA accepted encodings,
WAS will also use "converter.properties" for the JSTL params

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty - JavaServer Pages (JSP)     *
****************************************************************
* PROBLEM DESCRIPTION: When using the JavaServer Pages         *
*                      Standard Tag Library (JSTL) param tag   *
*                      to include parameters to an URL, the    *
*                      resulting URL safe query string can be  *
*                      encoded incorrectly if the page         *
*                      encoding is set to SHIFT_JIS.           *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
If a JSP page with page encoding SHIFT_JIS uses the param tag
from JSTL to specify URL request parameters, an unexpected query
string will be produced. This query string will cause problems
at the time of decodification and some characters might not be
displayed as expected.

Problem conclusion

The JSTL used by the JSP engine was modified to consistently
encode the URL parameters with the encoding specified in file
converter.properties.

The fix for this APAR is currently targeted for inclusion in fix
packs 7.0.0.45, 8.0.0.15, 8.5.5.13, 9.0.0.6, and 17.0.0.3.
