OSB called stateful service & extracting Set-Cookie Transport header

Question

I need to call a Stateful Web service which returns a JSessionId (Set-Cookie) which I need to use to subsequent service calls. In my message flow, a service callout calls a web service which returns a JSessionId which is part of the Transport Header. I need to extract this value into a variable and use it to call a couple of other web service calls using Service callouts. I have tried numerous things listed below but failed
1)     In the service callout Response actions, I have added a Transport header to capture this into a variable but in vain
2)     Added a Transport header in the Response action on the main pipeline
3)     Used Inbound variable to extract however it turns up empty.
any useful ideas would be appreciated. Thanks

Answer 1

When you call the external service it returns a SessionID in the header?
If that is the case then test the service from sbconsole debug console and in the invocation trace check the value of $inbound variable within the context of service callout and check if external service has actually added a transport header for session ID.
