Re: How to implement choreography with Petals ESB？
There is no fitting solution for service choregraphies.
It is actually a topic in R&D projects we have.
If I had to implement one right now, with what is available in Petals, I would probably develop a new Petals component, that would send InOnly exchanges (one message in the exchange, no response or fault). This component would also manage states so that the choregraphy works. Roughly, I would not talk of choregraphy. I would talk about asynchronous exchanges between several applications.
