Hi Guillaume,
I am also interested in seeing such a feature, i.e. allowing the
properties of the initiating JBI exchange to be copied into the messages
leaving the process. Do you think it's a big thing to add ?
regards,
Roger
Hum, not sure if it will really help me.
Let me restate what I need: the incoming JBI exchange
contain a known property and I want to store it with the
process instance somehow (in a variable or any other way).
Then, when an invocation is performed, I meed to set this
property on the newly created JBI exchange.
This is not about correlation for the BPEL process itself.
And I can't reuse something generated by Ode as the property
value is usually already set on the incoming exchange.
So I'm not sure if the session ids can be used, especially
because i need to use existing values and not let Ode
generate those. And it seems there is no way to override that
currently: see BpelRuntimeContextImpl.initializePartnerLinks
I was thinking about using the MessageExchange DAO to set
the property, but my problem is that I haven't found a way
to retrieve the MyRoleMessageExchange that was used
to create the process when inside an MessageExchangeContext.invokePartner
call.

Hi,
I think you'll just need to do something like:
String mySess = mex.getProperty(
PartnerRoleMessageExchange.PROPERTY_SEP_MYROLE_SESSIONID);
String partnerSess = mex.getProperty(
PartnerRoleMessageExchange.PROPERTY_SEP_PARTNERROLE_EPR);
For more information on how we handle the correlations this way:
