Hi
We have IIB 9 advanced, and IBM BPM 8.5 standard, and we have a requirement to initiate a BPM workflow instance as part of a IIB message flow.
Following is my understanding :
1. I can't use he SCA nodes as I have BPM Standard
2. I can use REST Api, but for this I need to make a JSON message.
The message flow is triggered via a Soap call , which is modelled in the XMLNSC domain, since JSON message models are not supported, I can't use the mapping nodes.
What is the conventional way to deal with such scenario? Create the JSON using ESQL? the payload is pretty bit, around 400 elements, this will be a pretty big esql compute...
Is there some other way?

Well, you could write a JavaCompute node and create some kind of class that would serialize to a JSON message....
but you'd still have to call 400 setters.
Like even with a map, you'd still have to draw about 400 lines... |

True, but drawing the lines 'seems' faster than writing the set outputroot.json.. = ..
Is there any XML interface available for BPM standard?

Cut and paste is a wonderful feature?

XML over a REST interface? The WebAPI pureists will come for you in the night.......

So are ESQL reference variables...
Were you going to get around to moving this to a more appropriate forum, Mr. Moderator? |

If you are really keen to use the Mapping node then you could do it like this:
- Map to the required structure as an XMLNSC message tree
- Use a Compute node containing the single line
SET OutputRoot.JSON = InputRoot.XMLNSC;
It may not be quite as simple as that ( maybe some extra lines of ESQL would be required ), but at least the heavy lifting would be performed in a graphical map. Please note that this is mostly idle speculation on my part - I have never actually attempted this.

Thank you, will try and post what worked for me in 3 days.
When I asked about the XML interface, I meant anything other than REST  .

I'd double check with your BPM developers. We have been able to start a BPM process using a SOAP service running on BPM (Standard 8.0.1) |

Will recheck with them , they said they can create a soap service that is specific to a process , while we are looking for a standard Api that can start any process , like the REST interface,

Good point - yes, we are only using it for specific processes, and the WSDLs are tied to that particular process. |
