Hi Spyros,
Well, i tried launching a thread for each Web Service call, and it works
ok... but i need to use the return of Web Service in the right side of
the rule to, for example, insert another fact... so, i have to wait for
the execution...
What i want is to execute a set of actions (in the right side of a rule)
in a different thread.
But i will look for JMS to see capabilities, and to see if fit my purposes.
Thx for the help
Regards
Carlos V.
