PM82220: Null value returned when a JAX-WS web service retrieves the HTTP header value by header name

Fixes are available

APAR status

Closed as program error.

Error description

Once the server had been started and a request was sent with a
header of say, "ABCD", if a subsequent request was sent with a
header of "abcd" it is still received as "ABCD".  This will
cause problems whenever checking for a case sensitive key in
the http header map, and any part of the cached header name is
in a different case.

The problem is because the http headers are not case sensitive
but the keys used in the JAX-WS map which contains the http
data, are.  If WAS caches a value which is not in the same case
as what is expected from the JAX-WS map, then you never get the
correct value returned, even if the request has the header in
the correct case.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server retrieving HTTP headers from a       *
*                  JAX-WS web service request.                 *
****************************************************************
* PROBLEM DESCRIPTION: When a JAX-WS web service retrieves     *
*                      the HTTP header value by header name,   *
*                      get null values returned.               *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A JAX-WS web service which needs to read some customized HTTP
header value from the request. Most of the time this works
fine, but occasionally when the application retrieves the
headers, it gets null values returned, even though the headers
are in the request.
When getting the customized HTTP headers, the default behavior
is searching and caching the header name in a case sensitive
manner. Once the uppercase header name, like "ABCD" is cached,
if the next request asks for header name "abcd," it will
never get the header value due to the case sensitive search
for the name.

Problem conclusion

According to the HTTP Protocols, modified the get method for
searching and retrieving HTTP headers to be case in-sensitive.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.29, 8.0.0.7 and the fix pack after 8.5.0.2.
