Re: [rules-users] Is work item configuration needed at run time? Can it be built programmatically?

Mike, The work item definitions file is only used in the graphical editor, to add custom nodes to the palette. It is not used at compile or runtime, as the variable definitions etc. are all part of the work item itself. So you probably don't need it in your environment. Kris Quoting msully

[rules-users] Traversing the Rete Network

Hello, I am trying to find out if and why a rule is not activated/fired when asserting a piece of data. At the moment I am using JBoss AOP to pointcut the method EntryPointNode.assertObject(), and from there I run an algorithm to walk to every node in the rete network. My question is how can I be

Hi, I downloaded standalone Guvnor: http://download.jboss.org/drools/release/5.0.1.26597.FINAL/drools-5.0-guvnor-standalone.zip and then began reading the documentation to get idea how to start with it: http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-guvnor/html_single/index.html

[rules-users] Compatibility of Drools for High Traffic events

Hi, I'm planning to use drools to define rules and execute promotions for telecommunication events such as voice call, SMS, MMS, etc.. events. So we can expect very large amount of events per day. We need to define different business rules to provide promotions, bonuses to the subscribers. Some

Re: [rules-users] Compatibility of Drools for High Traffic events

I've been doing similar things in an ESME (direct SMSC connection) but without rules, as the conditions were much simpler, and just handling SMS messages themselves. I guess you'll base your decision on billing records, possibly in connection with subscriber data. Billing records might be a bit

[rules-users] Updating the knowledge base manually...

Hi, I'm very new to Drools and don't know if this is possible, but i'm trying to manually update the knowledge base with the following steps : 1. Retrieve a knowledge builder from KnowledgeBuilderFactory 2. Load a drl rules file into builder 3. Create a knowledge base with the knowledge

Re: [rules-users] Updating the knowledge base manually...

First of all, your approach does not sound like a good approach. If you are removing all rules and adding new ones, why not simply create a new knowledge base? Anyway, by default, drools fires all rules right after a rulebase is updated. To disable this behavior, you need to set a knowledge

Re: [rules-users] Compatibility of Drools for High Traffic events

Thanks for the quick response. Yes, the events will be collected from the CDR(caller details records) files. We will decode the CDR files and store in a database. So the Rule Engine should be able to process these events to identify who are the candidate winners. This winner selection criteria

[rules-users] functions .drl file

Is it possible to create a .drl file of nothing but functions then import those into another .drl file to make it easy to maintain one file of API style functions and then beable to call them from any additional .drl files? Thanks, Chris ___

[rules-users] OSGI, classloading, and imports in KnowledgeBuilder

So I'm playing with Drools in Equinox OSGi, and so far it's behaving quite nicely - one bit of weirdness though. What I'm trying to do: I have a bundle with a 'flow manager' that listens for instances of WorkItemHandler in the service broker (well, really my own subinterface that has a getName

Re: [rules-users] OSGI, classloading, and imports in KnowledgeBuilder

Update: The plot thickens. Sometimes when I'm importing my domain class in the rulesflow, it works, and sometimes it does not. This seems to be tied to the class loader that happens to be in the current thread context. Sometimes it is org.eclipse.core.runtime.internal.adaptor.ContextFinder and

Re: [rules-users] functions

Chris, If you are creating a function library, why don't you create it as static methods in a java class? easier to develop, to unit test and you can use import function in the DRL to import all of them. []s Edson 2009/6/18 Chris Richmond crichm...@referentia.com Ok…I am trying

RE: [rules-users] functions

Edson, Thanks.and I am considering that option as well.but the nice thing about the functions in the drl file is the system remains much more fluid..in other words, if I can focus on doing what I want to do all within the DRL file, it proves the flexibility of the system more to me than having

Re: [rules-users] functions

Chris, I understand. Although functions in DRL files where conceived to be very simple things to reside with the rules. So, although you can have a DRL file with all your functions and, as long as this file is the first you load into your knowledge builder, use the functions on other files,

Re: [rules-users] functions

The only requirement in this case is that when you create the KnowledgeBuilder and starting adding the resources to it (DRL, flows, dsls, etc), a given resource can only reference an asset that was previously loaded. So, you must make sure the DRL with your functions is the first resource to
