I understand a business process model can be triggered by three ways… by publishing broker docs, JMS triggered processes and by simple service. I have a question on how would i handle if first step in process is webservice call i.e. provider webservice…is there a way process gets triggered when client calls the webservice?
Process model can be invoked from the Webservice call as well, which is your question as well.
For example, the IS service u hosted as provider thorugh a WS-connetor, provide in the implementation tab of ur process step. So when customer will call this service through Webservice invocation… your process model will be trigger.
