What is the difference in using a rules engine like drools as opposed to
using either an object database or ORDBMS mapping to a database with
triggers?

Jeffery,
We are definitely going to run the Drools 5, only the compiler and
engine part, under jdk 1.6 since this is going to be the version for our
production environment. We just integrated the pre-release Drools 5.0
for the new project under development; so far no issues for our usage.
Thanks
Can you open a JIRA for this? If you provide a unit test with it, we'll
see if we can include this in 4.0.7. 5.0 will now have shadow proxies
any more, as default.

I'd create a function called isEmpty, or call of a static method on a class.

Ming, from Sabre, is looking into it. He has fixed some thngs already.
Would be nice to support it, assuming we can fix all issues.

Thanks Mike!
I'm a total newbie here with Drools, so what I'm going to do is to take your
solution and try it out.
Cheers!

I'm not using Drools yet; was thinking whether would I gain from using
Drools with my situation and more importantly whether could I achieve what I
need to with Drools.
Actually even before coming to the cost calculation, there're a bunch of
business rules that I need to apply to determine if I ne
Thanks Steve,
This fixed the problem!
For Cheng Wei Lee's benefit this is the complete solution (I had to fix
another part):-
public class DBUtils {
public Collection getNumbers() {
Integer[] numbers = new Integer[10];
for (int i = 0; i < numbers.length; i++) {
without knowing how you are accessing the database your two algorithms come
down to something like:
Alg. 1
max(select max(p) from y, select max(t) from z)
Alg. 2
select min(p) from y + select min(t) from z
which is basically the same as what Michael has proposed.
Personally I think if you are a
change DBUtils to return a Collection and it should work I think.

I believe this is an example of backwards-chaining.
(From the manual) Drools only supports forward-chaining at present although
"...Drools will be adding support for Backward Chaining in its next major
release...".

So, in my usual helpful manner I thought Drools would be a perfect match and

Hi,
I have an object 'VenueGlobal' with a property 'sousVenues' who is a List of
SousVenue. I try to test the emptyness of this list in on sentence but i
don't know why it doesn't work :
I try this :
VenueGlobal( sousVenues == null || sousVenues.empty )
but I have this error :
