bpel process name from soap headers

[ericnygma <pr...@gmail.com>]

Hi ,

I am new to ODE (and to BPEL). I gather a bpel process has a chain of
webservice invocations. I have middleware code on an appserver hosting
webservices which inspects soap messages received by a webservice. Looking
at the soap headers/payload of a webservice invocation I need to determine
the name of the process which was invoked. I have a scenario in which a
webservice can belong to multiple bpel processes.

Does ODE attach some special headers ? .. or anything .. to identify the
parent process name.

Any help will be much appreciated.

Thanks
Eric.

To route messages to a specific process (or more precisely a process
instance), WS-BPEL relies on a mechanism called correlation. Basically, you
specify in your process what will be its identifier when a first message
initiates it. So any identifier used by your services (an order id, a
reservation id, ...) can be used.

I know specs can be hard to read sometimes but you should have a look at the
correlation section of the WS-BPEL spec. Alternatively there's also the
webinars published by OASIS that are linked here:
