Service Design

[andre1001]

Hi,

I've been wondering what would be the best design in the following situation...

There is an entity (EJB3) called PostalCode which can be updated in some sittuations. When I update it, I want to call another service in order to do some other tasks.

What would be the best?

1 ) Call service from my EJB passing it from a Producer to a Consumer. This sounds weird because it seems that I'm subverting layers (EJB calling Integration).

ESB -> EJB -> Another Service

2) Indicate to ESB a sittuation where it should redirect a message to another service.

ESB -> EJB throws BussinessException -> ESB -> Another Service

Thanks.

Have you looked at the jBPM integration with ESB? If you're looking at task-oriented programming (e.g., do this, then that, and if this then go the other) then you should look at jBPM, which can co-exist with the ESB.
