Start BPM from WDJ with Web Service (in 7.2)

Question

Hi,
I created a BPM process, and a new WDJ application to start the BPM process.
In the WDJ application, I created a new model (adaptive web service model) and I added this to the 'Used Models' of the application.
But, now, I want to start my BPM process after I click the "Submit" button. How can I do this?
In my RequestModel, I have my Model class with:
- ServiceData
- Request_StartOperation
- Response_StartOperation
(and my data element fields)
- Request_wbs
- Request_wbs_ca
- Request_wbs_tr
Now my question, How can i trigger the web service in the WDJ so the process can start?
wdDoInit:
RequestModel model = new RequestModel();
My event:
fireStartRequestCompleteEvent
Many thx!

Hi Hans,
You need to create an instance of Request_StartOperation and assign the values to the nodes/attributes under this. Once all the assignments are done, you need to bind it and execute the model as below example shows:
Lets take the model structure as below:
Model1 -> Request_StartOp -> StartOp -> Node1
Node1 -> Attr1, Attr2 (Node1 contains 2 attr and the type in WS schma is Node1Type and cardinality 1.1)
Model1 objModel = new Model1();
Request_STartOp objReq = new Request_StartOp(objModel);
StartOp objStart = new StartOp(objModel);
Node1Type objNode1 = new Node1Type(objModel);
objNode1.setAttr1(val1);
objNode1.setAttr2(val2);
objStartOp.setNode1(objNode1);
objReq.setStartOp(objStartOp);
wdContext.nodeRequest_StartOp().bind(objReq);
wdContext.nodeRequest_StartOp().currentRequest_StartOpElement().modelObject().execute();
Hope this helps.
Cheers,
Arafat
