Hi Meeraj, You can have a look at the ODE Axis2 integration layer to understand how BPEL server is initialized and how you can invoke process through ODE API. We have separate integration layer implemented for WSO2 BPS using the knowledge we get from ODE's Axis2 integration layer.
Please first go through the Axis2 integration layer and tell us if you have any questions.
