Hi
The Fault Format in the HTTP Input has 3 options SOAP 1.1, SOAP 1.2 & HTML..
What's the simplest way to define a custom fault format ? By custom i mean, one of the following :
1. return faults in JSON (useful for rest services)
2. return faults in XML (custom tags)
The HTTPInput already handles serialisation of the exceptionList & it'll be great to reuse that, instead of writing that up again.
Any suggestions?

Hi
So here's what I tried,
I added a compute node to the catch terminal of the Input node, parsed the exception list and generated a JSON & sent the reply back via the Reply node.
But when I do that, the message flow is committed, this is documented as well
| Quote: |
If you connect the Catch terminal of the input node, you are indicating that the flow handles all the exceptions that are generated anywhere in the out flow. The broker performs no rollback, and takes no action, unless there is an exception on the catch flow. If you want any rollback action after an exception has been raised and caught, you must provide this in the catch flow.
|
How do I rollback from within the catch flow?
( I could use Throw, but that that rollbacks the custom JSON that I just constructed .. )
Any suggestions?

Put the throw node after the reply node - HTTP Replies cannot be rolled back.
