Hello -
I am very, very happy with Jbpm4, and I am currently looking for a hint on
best practices for handling failures of automatic activities invoking retries
or failovers - for example, a whose class connects to an external server
(which may be down at the time of calling)
I understand I can signal the failure in the return variable and model
the retry / failover process explicitly with a switch, but that seems rather
cumbersome.
My preference would be to have the possibility to implicitly choose from
the activity the outgoing transition, pointing to a "retry" state which
periodically re-enters the automatic activity with a timer. I am not sure if it
is possible to define that an exception in the java class with
exception-handlers, because the docs seem incomplete.
Also, about exception handling, I could not find any hints on these two
points:
1- what possibilities are there to "recover" a process that has
encountered an unhandled exception?
2- will other process instances running in the same PVM keep going in
such a case?
Any pointers woud be really appreciated.
Bye and thanks.
