Drools can be written in XML as well as normal DRL. The XML method of writing
Drools is friendlier for GUI's.
My suggestion, was that instead of creating your own XML language for storing
Rules, you could maybe re-use the existing XML language provided by Drools and
use the default rule parsing
Hello,
I would like to store rule entry in my database while using Guvnor. So
whenever any rule is added/removed from Guvnor, I want to add/remove the
same from database table. Is this possible?
Is there any event handler called in Guvnor while adding/removing rules?
Please clarify.
Thanks.

Hello Vikrant,
Sometime ago, you replied to my question as given below. I don't get this
statement. "For the GUI, you could use XML rather than create your own
language and let drools compile things automatically. ".
can you please elaborate?

Nope. See the StatefulSession.async* and StatelessSession.async* methods.
They are threadsafe.

There's probably an easy explanation for this. I was wondering about why
functions inside of rule files can't access globals?
For example, I have a log4j logger that I pass into my rule files via a global.
The logger should never be a part of working memory. It's just there to
capture valuabl
Thanks. That's the plan. However, my assumption is that even if the
data model and rules support partitioning that you still need to
synchronize calls to working memory so that two threads aren't invoking
insert, fire*, retract, etc. at the same time.

That model sounds quite reasonable. You may also find it useful to partition
your rules by user by having them match on a User object of some kind and user
state that matches up with each User.

$u : User();
UserState(user == $u);

Thanks for the confirmation. I think it should be straightforward to
implement a parser as you suggest to populate a list of java beans and
assert them to the working memory. I'm just surprised that this doesn't
already exist.
May I ask how you manage the working memory? It looks like you can'
Hi Jess,
I am facing the same problem right now. While, I do not know of any OOTB ways
to do this, I initially implemented an all rule solution.
In my case, I had a lookup table that based on a age or gender got a rate or
some value.
Using some Excel Trickery, I got the 2 dimensional table into
I'm trying to come up to speed on the drools capabilities. I see that
drools supports loading rules from a decision table in a spreadsheet. I
have a set of conversion tables that I'd like to represent as facts
asserted when the rule base has been loaded, but before processing user
requests. I co
Will there be any issue if we use the same package in multiple rulebases? I
saw a comment in one of the posts which states - "Just make sure the only
thing you eventually share among threads is the rulebase. Do not share
session or packages among threads."

Hi there,
I'm in need to modify the Drools BRMS to use a JCR exposed over JNDI.
I successfully deployed Jackrabbit over JNDI (I can access it via an EJB and
making a context.lookup()), but I can't get it to work in JBRMS. I modified the
