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 be
Yes..for the most part, a non developer wouln't be able to write the rules
anyway..you need someone with domain knowledge of the objects being
injected, so I don't see a non developer writing rules.I was trying to

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,
That's a great idea Edson. I just found Mark's posting on this from 2006:

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
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.

Here's the ClassLoader that let's the import work:
org.springframework.osgi.util.BundleDelegatingClassLoader
OK, I realize this is starting to seem like a question for another board,
but I figured I'd put all the info here since I started here.
If I find the solution elsewhere, I'll share here.
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

Thanks Kris - it did work as you described. Got another issue, which I'll

Thanks again,

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,

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 can
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 packages
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

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 bu

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.
