I have a problem to start a Bpm process by web services.

What i do:

1) Create a model starting by the webservice (wsdl of "Process Modeling->Service Interface")

2) Configurate the task

3) Configurate the "Start" element with the previous task and the mapping output

4) In "SOA Management->Technical Configuration->System Connections" configurate a Profile

5) In "SOA Management->Technical Configuration->System Connections" configurate a Provider

6) In "SOA Management->Application and Scenario Communication->Business Scenario Communication" configurate a scenario with relative Service Group

7) In "SOA Management->Application and Scenario Communication->Single Service Administration->Service Definition" configurate the "End Point"

8) Test with Ws-Navigator.

When i use the execute method of the model i have an excepion.

I check the "SOA Management->Logs and Traces->Web Services Logging & Tracing", and i see in "WS Role"="PROVIDER"

the follow error:

-
