[rules-users] Looking for a Drools Resource in the Bay Area

2008-12-11 Thread Nick Heudecker
Hi, I'm looking for a Drools resource in the Bay Area to help me determine if a rules engine would benefit the application I'm building now. I've been exploring Drools for the better part of two weeks and I'm honestly not seeing the advantage of using it for my problem. I understand that's not v

[rules-users] different version between brms and drools-api/core: problem in serializing/deserializing pkg?

2008-12-11 Thread Brody Bach
Hi all, just wondering if there could be any problem in serializing/deserializing the pkg file when the version of brms used to export it is different with the version of the drools-core/api. (e.g BRMS 4.0.7 and drools-coreM3) Do I have to keep the version synchronized? Thanks a lot BBach

Thanks Michael. Actually we could make it work using "mvel" dialect instead of "java" one. We find "mvel" dialect makes it easier to write rules (no more getters, and getters are not very natural for non developers) so it could be a nice idea to use it. But are there things that can be done with Ja

Hi all, just some further questions regarding Guvnor: I would like to use Guvnor for managing my rules with an external RDBMS for storing them, and later on fetching the rules directly from DB from my application, how can I do this? in which kind of datatypes are the rules actually saved in dat

Well the exact semantics or "otherwise" or "else" are never really agreed upon, As there is more to it then meets the eye. A global style "otherwise" is not too hard to do. But "else" is what a lot of people want. Sent from my iPhone On 11/12/2008, at 3:41, Ravi Krishnamurthy <[EMAIL PROTECTE

Re: [rules-users] Performance question - eval on a HashMap vs. from on an ArrayList

If the number of items are small , its probably much of a muchness, and the difference would be hard to predict. The "from" kind of looks more declarative compared to the eval - its probably better. Sent from my iPhone On 11/12/2008, at 13:29, "steve.vance" <[EMAIL PROTECTED]> wrote: H

Hi, We plan to use rules engine on a project because business rules will often change and need to be written by business experts. We are testing Drools 4.0.7 and are very interested with it, in particular because of the ability to write DSL. In our tests we wrote a rule that needs nested properti
