Getting error while Startting a BPM process programmatically

Question

Hi Experts,
I am getting an error while trying to start the BPM process programmatically. What i have done till now is
1. Created a WS in process composer
2. Binded this ws with start of the process
3. Created input parameters
4. Testing it in WS Navigator
I am following this doc /people/arafat.farooqui/blog/2009/08/13/introduction-to-sap-netweaver-bpm-part-4
and I am getting error while testing in WS Navigator. I am getting error at the last step i.e. in result step and the error is
Web Service returned an error. Fault Code: "(http://schemas.xmlsoap.org/soap/envelope/)Client" Fault String: "No operation found using soap keys [], [cn_comments]. InterfaceMapping Object class: com.sap.engine.services.webservices.espbase.mappings.InterfaceMapping mappings: (BindingType=Soap, SEIName=NewWSDLFile, BindingQName=(http://www.example.org/NewWSDLFile/)NewWSDLFileSOAP, PortTypeQName=(http://www.example.org/NewWSDLFile/)NewWSDLFile, SoapVersion=SOAP11, Galaxy_SDO=true, InterfaceMappingID=45ffb27c:1237f972cd8:-7d7e)."
If possible can any one help me out.
Thanks and regards

Hi Arafat,
Thanks for replying. Yes i have completed the output mapping. Input parameters i need for this service are :
1. cn_comments
ca_comments
2. cn_planningGroup
ca_account
ca_serialnumber
and few more attributes
Now, what i did was i have created a complex type and added elements in it. But to my surprise i was not able to get these nodes and elements in output mapping. So, i changed the type of "parameter" from "new operation" to my complex type. By doing this i was able to get my nodes and elements in output mapping. Now i tested the entire thing in WS Navigator and i got that error.
Please suggest how o proceed.
