Hi,
I am working with Drools to implement a high-profile rules-engine. I have
two rules defined. Clearly, only the first should fire, but both do. Here is
my DRL:
package com.sample
import com.sample.DroolsTest.Request;
rule "ExpensiveCanonShopper0"
when
Request( attributeMap["ca
Hi all,
I think I've found a bug in DroolsStreamUtils.
It does not allow to deserialize a collection of KnowledgePackages with
dependencies between the packages. In this case, it fails with
ClassNotFoundException.
Example: Package A contains a type declaration, package B contains a
rule using thi
Ok, this is fixed:
https://issues.jboss.org/browse/JBRULES-3224
I will check JBRULES-2995 now.

Thanks Wolfgang. That is a different issue related to how MVEL deals with
class literals. I will check what's the status on it anyway.

Thomas,
Thanks for reporting. I will look into it.
Did you open a JIRA yet? Let me know or I will do it otherwise.

Thanks for your suggestion about activating the console logger. That helped
me find out what's going on. After I fixed a stupid logic error on my part,
I found out that my basic solution will work. When the user decides to
cancel the session, I need to make sure that the current rule's RHS

That's a nice one.. We will definitely create a test for that.. if it's not
there..

I've just tried upgrading from Drools 5.3.0-CR1 from the beta and I've hit a
regression.
JBoss seems to have been down for most of today so I haven't been able to raise
a Jira for it.
In our model we have Facts which contain fields of java.lang.class, we then
have a rule which checks that they
Hi,
If you have a lot of rules like it you might be able to use the jBPM (what
what the Drools Flow) to help with this. Otherwise plan old java might be
easier...

As I said, try reading the expert doc, there's some examples in there which you
can base your code on.
Once you've done that or if you have any questions about the samples/what the
documentation means
then post them and we'd be pleased to help, but the first step is to structure
your code correc

Hi,
it seems to me that you are using the wrong tool to solve your problem.
Drools is a rule-based execution engine (among other things) not a

Have you read the expert guide?
http://docs.jboss.org/drools/release/5.2.0.Final/drools-expert-docs/html_single/index.html
- At least up to the end of chapter 4.
Why are you using static fields and methods?
You are changing the value of objects in the when condition which is really

these are my rules:

$info.printResult(1);
end

I have this strange problem, when I call
int taskId = 105; // dummy taskId, the real one is obtained
through TaskSummary
BlockingTaskOperationResponseHandler b = new
BlockingTaskOperationResponseHandler();
client.complete(taskId, "myusername", null, b);
while
You missed the second part of the instructions - once a rule has matched you
need to make sure the other rules don't match.
This can be achieved in multiple ways:
Call the engines halt method - just stop evaluation.
Retract the facts - then nothing else can match it.
Update the facts to stop the c
This isn't an if statement evaluated left to right with an && between each part.
Drools uses the rete algorithm to make execution more efficient.
Put very simply (and probably inaccurately) Rete creates an evaluation tree
where inputs are put in the top and activations come out the end.
In this ca
take a simple scenario:
when
condition1
condition2
then
...
Does the condition2 gets executed even if the condition1 is false, normally
it should not because the conditions in the when are actually combined with
an AND. Has anywhen tried this??
