LOCAL FIX:

PROBLEM SUMMARY:

USERS AFFECTED:
 WebSphere Application Server users of Web
Services Atomic Transactions

PROBLEM DESCRIPTION:
Provider side processing of a Web
Service request containing a WS-AT
Context fails with
java.lang.ClassCastException

RECOMMENDATION:
None

If a Web Service provider is configured to support both
WS-Atomic Transactions and WS-ReliableMessaging then a
java.lang.ClassCastException occurs when the provider is
processing the response to a request containing a WS-AT
context.
It should be noted that WS-RM and WS-AT cannot be used on the
same request by design, however it should be possible for a
Web Service provider to be configured to support both WS-AT
and WS-RM so that either of those qualities of service are
available on a mutually exclusive basis.
The ClassCastException occurred because the WS-AT component
inserted a plain OMElement directly into the SOAPHeader rather
than a SOAPHeaderBlock.  Later processing by the WS-RM
component cast the SOAPHeader's child directly to a
SOAPHeaderBlock.

PROBLEM CONCLUSION:
The WS-AT component was modified to add a SOAPHeaderBlock,      
rather than a plain OMElement, to the SOAPHeader.               
                                                                
The fix for this APAR is currently targeted for inclusion in
