Just remove the entire rule and re-add it again, but with a different
consequence.

Hello All:
I am trying to figure out if JBoss Rules will be suitable for my
application
needs. Maybe you can give some insight.
My application needs to implement / use a rules engine for evaluating
conditions and firing off events when those conditions are met.
So far this
sounds exactly like the sort of thing that JBoss Rules is for.
The twist is
that my application will also provide an administrative utility
that allows
admins to add or remove rules, as well as modify the conditions
that trigger
these rules. Can JBoss Rules be used to do this? All of the
examples I've
seen so far seem to incorporate rules whose consequences are
fixes, but with
changeable conditions. For example, there are lots of samples out
there
like an insurance application. Such an example has consequences
such as
offerQuote, turnDownCustomer etc. that don't change, but with
conditions
that do change. For example, today offer quotes to all good drivers,
tomorrow change the rule to offer quotes to all good drivers over
the age of
18. The conditions change, but the basic actions in the system
are common.
What I think my requirement implies is a way to define rules with
conditions
and the corresponding consequences code at runtime. This seems to
imply
that the application code needs to be dynamic, in order to allow
users to
define arbitrary consequence code. Has anyone ever tried to do
something
this generic with JBoss Rules, and better, can you fill me in on
how to go
about this?
Thanks, Robert
