Error description

  • The Webservice response message may contain the following
    Fault...
    
    <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soape
    nv:Body>
    <soapenv:Fault
    xmlns:axis2ns1="http://schemas.xmlsoap.org/soap/envelope/"><faul
    tcode>axis2ns1:MustUnderstand</faultcode><faultstring>Must
    Understand check failed for header soapenv
    :{http://schemas.xmlsoap.org/ws/2004/10/wscoor}CoordinationConte
    xt</faultstring><detail></detail></soapenv:Fault></soapenv:Body>
    </soapenv:Envelope>
    
    Another symptom that is possible is WTRN0006W messages which
    indicate that a transaction has timed out after a message is
    processed by a Service Integration Bus Resource Adapter Message
    Driven Bean.

    ****************************************************************
    APAR PM90220 removed function that prevented the transaction
    context associated with the thread when the SIB Resource
    Adapter dispatches an inbound message from being propagated
    via WS-AT on JAX-RPC requests.  As a result, transaction
    propagation may occur in instances where it previously did not
    resulting in unintended propagation of the transaction
    context.  This may cause the JAX-RPC request to fail
    generating a SOAPFault containing the following faultstring:
    <faultstring>MustUnderstand check failed for header soapenv
    :{http://schemas.xmlsoap.org/ws/2004/10/wscoor}CoordinationConte
    xt</faultstring><detail></detail></soapenv:Fault></soapenv:Body>
    </soapenv:Envelope>
    

Problem conclusion

  • The transaction context associated with the thread when the
    SIB Resource Adapter dispatches an inbound message will not be
    propagated via WS-AT on JAX-RPC Web Service requests unless the
    transaction was imported from the inbound message.
    
    This reverts the change of behavior introduced by APAR
    PM90220 for transactions of this type.
    
    A JVM System Property has been provided to allow such
    transactions to be propagated via WS-AT as per the function
    delivered in APAR PM90220.  To enable that behavior, set the
    JVM System Property
    com.ibm.ws.Transaction.wsat.allowSIBRAPropagation to a value
    of true.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.31, 8.0.0.9 and 8.5.5.3.  Please refer to the
