ReplyTo property missing in SOAPHeader - wso2

Question

I have created a WS-BPEL workflow that would call an asynchronous web service and wait for a callback response. The carbon application is successfully deployed into BPS as well.
Details on my external Asynchronous web service
1. It requires basic authentication over http.
2. It requires the soap header to be available in the soap envelope.
3. It would process the request and send a callback to the ReplyTo address it receives in the soap header and use the MessageID to correlate the callback.
My deploy.xml file for the BPEL process looks like this ...
<?xml version="1.0" encoding="UTF-8"?>
<deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03"
xmlns:callback.integration.service="http://callback.integration.service/"
xmlns:epr="http://wso2.org/bps/bpel/endpoint/config"
xmlns:sample="http://wso2.org/bps/sample"
xmlns:ws.integration.service="http://ws.integration.service/">
<process name="sample:Test">
<active>true</active>
<retired>false</retired>
<process-events generate="all"/>
<provide partnerLink="client">
<service name="sample:Test" port="TestPort"/>
</provide>
<provide partnerLink="IntegrationService">
<service name="callback.integration.service:IntegrationCallback" port="IntegrationResponsePort"/>
</provide>
<invoke partnerLink="IntegrationService">
<service name="ws.integration.service:IntegrationService" port="IntegrationRequestPort">
<epr:endpoint endpointReference="IntegrationService.epr"/>
</service>
</invoke>
</process>
</deploy>
The IntegrationService.epr file looks like this ...
<wsa:EndpointReference
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3schools.com uep_schema.xsd"
xmlns:wsa="http://www.w3.org/2005/08/addressing"
xmlns:wsdl11="http://schemas.xmlsoap.org/wsdl/">
<wsa:Address>http://http://server:8080/integration/IntegrationService</wsa:Address>
<wsa:Metadata>
<id>SInvokeEPR</id>
<qos>
<enableAddressing />
</qos>
<transport type="http">
<authorization-username>username</authorization-username>
<authorization-password>password</authorization-password>
</transport>
</wsa:Metadata>
</wsa:EndpointReference>
Now when I test the bpel process from carbon service management console, I do get a request to my asynchronous web service. However the soap envelope looks as followed and it is missing a proper ReplyTo address to send the callback.
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">
<wsa:To>http://server:8080/integration/IntegrationService</wsa:To>
<wsa:ReplyTo>
<wsa:Address>http://www.w3.org/2005/08/addressing/none</wsa:Address>
</wsa:ReplyTo>
<wsa:MessageID>urn:uuid:91ac4ebd-b100-440e-a01d-c4a5c0d8a56f</wsa:MessageID>
<wsa:Action>http://ws.integration.service/IntegrationRequestPortType/createTask</wsa:Action>
</soapenv:Header>
<soapenv:Body>
...
</soapenv:Body>
</soapenv:Envelope>
Now my need is to reply to this request with a callback. The callback soap envelope would contain this MessageID so that the callback correlates with the correct process instance.
How do you get the proper ReplyTo address appended to the soap header?

Answer 1

If I assume correctly you use the WSO2 BPS (or something with Apache ODE), you can use this copy in an assign to set the Header by hand. (http://ode.apache.org/extensions/headers-handling.html)
<bpel:copy>
<bpel:from>
<bpel:literal>
<wsa:ReplyTo xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Address>http://localhost:9763/services/SIServerCallback</Address>
</wsa:ReplyTo>
</bpel:literal>
</bpel:from>
<bpel:to variable="ServiceInvokerIARequest" header="ReplyTo">
</bpel:to>
</bpel:copy>
