Problem with class Variable
by Mehdi
hi,
I have a class Customer.java with class variable "allTradeAmounts" and
I have two rules as follows:
rule "rule 1"
when
$c : Customer();
then
$c.setAllTradeAmounts($c.getAllTradeAmounts().add(1000));
System.out.println("after modify: "+$c.getAllTradeAmounts());
end
rule "rule 2"
when
$c : Customer(allTradeAmounts < 200 );
then
System.out.println("AllTradeAmounts < 200 ");
end
The rule 1 works fine and changes the value of this variable.
My question is, although the rule 1 has changed the class variable and I can see the result of changed variable EACH TIME, when i insert a Customer object, why is the second rule TRUE? I have changed the value of AllTradeAmounts and I can print it in RHS and it is more than 200, but in LHS if I check with "allTradeAmounts < 200 " ,it is true.
It must be FALSE and does not fire the rule.
can someone help me? what do I do wrong in LHS.
In the same rule (rule 2) if I print the allTradeAmounts it is more than 200.
sorry it is a simple question, but I m new to drools.
Thanks and regards

problem in removing rule from rulebase
by prateek.katiyar＠wipro.com
Hello all
I am using Drools 4.0.3
I want to remove rules from a InvalidRulePackage during the run time of the java program.
For this I am using removeRule(String packageName, String ruleName) method in my program but it is giving me the following exception:

Re: Eclipse tools question
by J Michael Dean
I solved this problem, though not sure the exact cause. In Eclipse, I
had created a project in which I wrapped the Drools jar files,
exported the plugin, etc. However, I left the project in my
workspace. This apparently interfered with the Drools eclipse tools.
When I deleted the wrapper project from my workspace, the eclipse
tools for drools work fine.

Class import problems
by J Michael Dean
I am trying to import a class, but get a message that only a type can
be imported, and what I am trying to import resolves to a package. I
have used the examples and they appear to do the same thing, except
they work.
The top of my drl file is shown below. GlucoseDecision is, in fact, a
type. But this is inside a large Eclipse project. Do I have to, in
some fashion, separately jar the classes that I want to import in
Drools? Does not appear to be the case when I look at the examples.
package edu.utah
#import edu.utah.cdmcc.entities.Patient;
import edu.utah.cdmcc.entities.GlucoseDecision;
rule "First Glucose Rule First File"
when
eval(1==1)
then
System.out.println("First Glucose Rule First File got called");

Eclipse tools question
by J Michael Dean
I have created a drools "core" plugin that allows me to incorporate
Drools into an RCP. However, since doing so, the Eclipse tools for
Drools do not work properly, and there is indication of an error in
the drl file. Nevertheless, I can edit the file, the RCP runs with
the new rules, etc.
In my plugins, I have the main eclipse drools feature and plugin; in
my workspace I have the core drools project that contains the
compiler, core, and limited dependencies. I have also exported the
latter plugin, and dragged it into my eclipse installation.
Do these three different things foul each other up? Right now I do
not use a separate target for my RCP compilation, but just the main
IDE installation.
Very sorry if this is completely stupid - I am actually ecstatic that
I finally got the drools engine incorporated successfully into my
RCP. But the IDE is sure upset. Here is the trace when I try to save
the altered drl file (which does, in fact, save successfully despite
the trace):

How to check to rules syntax before runtime?
by Kevin Delcroix
Hi everyone,
I would like to check if the rules syntax is correct before the rule
runtime. In fact, the end-user is the one which edits the rules and
saves them into the database. At a specific moment, the rules code is
loaded and executed. But for the moment, the rules the end-user typed
are not checked before the runtime of the rules.
So I would like to check the rules syntax when the end-user validates
the rules pseudo-code and show him if there are errors in his rule code.
Don't hesitate to ask me if it's not clear enougth.
Thanks in advance for your help.
