Hi Tammo, I am now trying to retrieve the Process Model by parsing the bpel file. By process model I assume that it is the object of class org.apache.ode.bpel.compiler.bom.Process. Or is it org.apache.ode.bpel.o.OProcess that you were mentioning?
>From org.apache.ode.bpel.compiler.bom.Process object I get the root activity and then the sources and targets. But both of them are empty. In the org.apache.ode.bpel.o.OProcess object I don't see anything helpful except for children attribute. But that also doesn't guarantee any thing in the case of Flow. There are no traces of successor or predecessor in those activities. Or the process model you are referring to is something different from either of these?

Conceptually, this information should be enough to retrieve the process model from some kind of registry, however, I think there is no sound way to retrieve the model from ODE's process store from the event listener's scope. It would make a good addition to the management API though.
