Error description

    Context, processing fails with a java.lang.ClassCastException
    when marshalling the response.
    
    The call stack associated with the error is of the form:
    
    AxisEngine    E org.apache.axis2.engine.AxisEngine receive

    ****************************************************************
    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
    fix packs 8.5.5.16 and 9.0.5.1.  Please refer to the
    Recommended Updates page for delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • The error occurs when using the default deferred registration
    optimization for WebSphere Application Server to WebSphere
    Application Server WS-AT.  This optimization can be disabled
    by specifying a new Transaction Service Custom Property with
    name DISABLE_WSTX_DEFERRED_REGISTRATION and value true
