[rules-users] Weblogic rules to Drools rules.

[Edson Tirelli]

   You mean there are 40-50 conditions like that in a single rule? It is not
that you can't do, but how do you maintain such a thing? Sounds to me that
you need to step back and re-evaluate the way you are modeling your rules.
It is hard to point you to any direction based solely on the information in
this e-mail. If you have an example maybe? or if you are a Red Hat
subscriber, you could contact an SA to help you on this...
