WSO2 Service Chaining Request to Service not send to server but ends in default fail sequence without details

Question

I am performing a PoC with WSO2 ESB.

I have 3 service stubs, 1 is de request to Personen and it sends back a CSV list of persons with their organisation.

Then two services for each organisatie (Organisation1 and Organisation2) that accepts this CSV string in it's addPersoon method.

Very straight forward, iteration stuff. But when I created the SOAP message and send it to the services it is not received but instead ends in the default "fault" sequence and there's no hint as to what is wrong:

Any suggestions for this newbie are welcome Thanks!

Answer 1

When you say

"... and send it to the services it is not received but instead ends in the default "fault" sequence"

Do you mean you sent the message to the proxy service , or the individual services? If the latter , you need to get the correct endpoint's of the PROXY SERVICE (by clicking on the service in the consoleUI->services tab). The proxy will chain your services.

Also , if the message flow hits a < drop > mediator anywhere , it will immediatley stop processing of message.

And by the default fault sequence do you mean the esb's default fault sequence or the fault sequence you specified?

And can you paste some logs and the soap request.
