Example use of WS-Addressing information in the local environment

In this example the Web service exposes a simple ping operation.

ESQL to add reference parameters

The following ESQL example shows how to specify addressing headers in the local environment.

DECLARE Example_ns NAMESPACE 'http://ibm.namespace';

SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.ReplyTo.ReferenceParameters.Parameter1 = 'Message Broker';
SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.ReplyTo.ReferenceParameters.Example_ns:Parameter2.
 (SOAP.NamespaceDecl)xmlns:Example_ns = 'http://ibm.namespace';
SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.ReplyTo.ReferenceParameters.Example_ns:Parameter2 = 'Ping';
		
SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.FaultTo.ReferenceParameters.Parameter1 = 'Ping';
SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.FaultTo.ReferenceParameters.Example_ns:Parameter2.
 (SOAP.NamespaceDecl)xmlns:Example_ns = 'http://ibm.namespace';
SET OutputLocalEnvironment.Destination.SOAP.Request.WSA.FaultTo.ReferenceParameters.gns:Parameter2 = 'FAULT';

Request message

The following example is of an outgoing SOAP envelope in a message from a SOAPRequest node with ReplyTo and FaultTo reference parameters generated after using the above ESQL. It also shows the other message addressing properties (MAPs) that are not set in the local environment, but are generated automatically by the node as a result of engaging WS-Addressing.

<NS1:Envelope xmlns:NS1="http://www.w3.org/2003/05/soap-envelope" xmlns:wsa="http://www.w3.org/2005/08/addressing">
  <NS1:Header>
    <wsa:To>http://localhost:7801/Service</wsa:To>
    <wsa:ReplyTo>
      <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>
      <wsa:ReferenceParameters>
        <Example_ns:Parameter2 xmlns:Example_ns="http://ibm.namespace">Ping</Example_ns:Parameter2>
        <Parameter1>Message Broker</Parameter1>
      </wsa:ReferenceParameters>
    </wsa:ReplyTo>
    <wsa:FaultTo>
      <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>
      <wsa:ReferenceParameters>
        <Example_ns:Parameter2 xmlns:Example_ns="http://ibm.namespace">FAULT</Example_ns:Parameter2>
        <Parameter1>Ping</Parameter1>
      </wsa:ReferenceParameters>
    </wsa:FaultTo>
    <wsa:MessageID>urn:uuid:020C911C16EB130A8F1204119836321</wsa:MessageID>
    <wsa:Action>http://ibm.com/Service/Ping</wsa:Action>
  </NS1:Header>
  <NS1:Body>
    <NS2:Ping xmlns:NS2="http://ibm.com"></NS2:Ping>
  </NS1:Body>
</NS1:Envelope>

In the above example, reference parameters are set for the ReplyTo and FaultTo endpoint references (EPRs). If this message is sent to a SOAPInput node with WS-Addressing engaged, these ReferenceParameters are placed in the local environment of the flow that contains the SOAPInput node for use by the flow if the Place WS-Addressing Headers into LocalEnvironment property is selected. This option changes only what is placed in the local environment; it does not change the contents of the response message.

Response message

The following SOAP envelope is a response to the outgoing preceding message, as sent by a SOAPReply node. This example shows the MAP processing that happens automatically by the SOAPReply node. In this example, the FaultTo reference parameters are not present because the reply is not a SOAP fault. This response also shows where the reference parameters that belonged to the ReplyTo EPR appear in the response message.
