[rules-users] Auditing Requirement
Hi, We have a requirement were in we want to create an audit report after rules have been executed. For each rule, we need to track Desired Condition Value(as specified in when part), Actual Condition Value(value in asserted object) and so on. This data is to be collected not only for rules which finally got fired but also for rules which failed. It would be great if someone can guide me how to achieve this. Regards Manrai ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Setting date during execution of rules.
Effective dates in 4.0.x come from Calendar.getInstance() so unless you change the time that the java Calendar sees you cannot go back in time. Trunk, and 5.0 (TBR in Q2/Q3), has a class called TimeMachine which allows you to set the date. If you need control of this, and in 4.0.x, you will not be able to use the effective date attributes. Instead I recommend you create your own hashmap ofr effective dates per rule and use the agenda filter to excludes ones that aren't within the allowed dates. Mark Nimesh Muley wrote: I was not able to portray the right picture L. Here's another shot at clarifying my situation. Let's say we have a commission rule as follows rule Commission Calculation *07-08* *date-effective 01-Apr-2007* *date-expires 30-Mar-2008* when then end Now for the next financial year we define a new rule as follows rule Commission Calculation *08-09* *date-effective 01-Apr-2008* *date-expires 30-Mar-2009* when then end Now let's say /_today's date is 15^th April 2008_/. An agent is promoted today with /_effective date as 1^st March 2008_/. Hence his commission needs to be recalculated as per the Commission Calculation *07-08* rule and *_not_* the effective rule as on today i.e. Commission Calculation *08-09*. For rest of the agents commission would be calculated based on the rule effective today i.e. 15^th April 2008. Hence a need to pass a date during execution of rule based on which the right rule would be chosen. Basically there is no legacy code as part of my example but a need to fire the rules that are effective on a date other than the system date always. I have seen similar functionality in other rules engines too. Can this be done in JBoss Rules? If yes, is TimeMachine the right way of doing it?

As I understand it, the problem is that you have legacy code that uses the system date in it's calculations and you cannot fix that so it will take a date parameter, right? If so, then my recommendation is to fix the legacy software if possible since messing with the system date gives me the willies. If you can't fix it, then anything that can be called from Java to set the system date (e.g.Runtime.exec(...).waitfor()?) should be callable from the 'then' part of a rule. Make that call, call your legacy code, then make the call to set the date back. But that is so ugly, please don't tell anyone I had anything to do with it. Nimesh Muley's message received 3/5/2008 1:25 AM: Hi, Is there a way to set the date while executing the rules? The effective dates would be checked against this date instead of today's date. By default the effective dates would be checked with System date. But in some cases we would need to execute the rules in a 'back-dated' mode. Use case. Let's say in insurance industry there are commission calculation rules for an agent. On these rules the effective dates are appropriate (as per their needs). Now when an agent is promoted and his/her promotion date is couple of months back then we would want to calculate the commission once again with the date as 2 months back. The nearest I could see is TimeMachine, as this is being used during execution of rules. Although I could not find a way to set the TimeMachine in release 4.0.4. Has anyone tried something like this before?

is something wrong in the Drools LogicMy issue can be very easily be
recreated in about 5 minutes
From eclipse I set up a new drools project.Where DroolTest.java is
defined I create 4 new classes, ClassA, ClassB extends ClassA, ClassC
extends ClassA, and ClassD.
Each of these classes has a default constructor that does nothing, there are
no attributes or anything in these classes just to make the example simple
to reproduce. Ie ClassA looks like this
package com.sample;
public class ClassA {
public ClassA() {
}
}
Now within the DroolsTest.java source code at line 29 (ie right after the
workingMemory.insert( message ) method call I added 4 more lines which
creates and inserts two objects...
ClassB classB = new ClassB();
ClassD classD = new ClassD();
workingMemory.insert( classB );
workingMemory.insert( classD );
and then the next line would be the
workingMemory.fireAllRules();
as normal.
Then in the sample.drl file I add the following rule and functions
1 rule Test
2when
3
4 $classA : ClassA()
5 $classD : ClassD()
6
7 (or
8 $classB : ClassB(eval($classB == $classA))
9 $classC : ClassC(eval($classC == $classA))
10 )
11
12 eval(retB($classA, $classD))
13
14 then
15 System.out.println(\n\nFIRE RULETEST);
16 end
17
18 function boolean retA(Object obj) {
19 System.out.println(Ret Val = + obj);
20 return true;
21 }
22
23 function boolean retB(Object obj1, Object obj2) {
24 System.out.println(Ret Val 1 = + obj1);
25 System.out.println(Ret Val 2 = + obj2);
26 return true;
27 }
So what I am doing is very quick and very simple to reproduce. What is
happening is that when i run the program I am getting a class cast exception
which is very very strange.
At first I thought it was tied only to the OR statement because if I break
the rule into two rules (one for each of the or conditions) it works fine.
But after playing with it a little further I get a lot of other strange
class cast exceptions.
For instance if I replace line 12 (eval(retB($classA, $classD))) with
eval(retA($classA)) it works fine, but if I replace it with
eval(retA($classD)) I get another class cast exception.Another strainge
issueif switch lines 4 and 5 and keep line 12 as eval(retA($classD))
that previously failed, it now passes, but if I change line 12 back to
eval(retA($classA)) which previously passed it now fails.
There are a few other combinations that produce errors as well. Just seems
to be a fundamental flaw in the logic and I'm curious if anyone else has
seen this?
Thanks!

P.S.
Also I've noticed an issue with the manual example 6.36
This does not seem to work for me
pensioner : (or Person( sex == f, age 60 )
Person( sex == m, age 65 ) )
But this does
(or pensioner : Person( sex == f, age 60 )
pensioner : Person( sex == m, age 65 ) )
Although both formats are stated as working in the manual.

[rules-users] Problem using Package Builder
Hi
I am using Package Builder for making rule base in my web application. The
code is:
public class DroolSetUp implements ResourceLoaderAware{
private static RuleBase ruleBase;
private Resource drlFiles;
public void setResourceLoader(ResourceLoader arg0) {
try {
ruleBase = RuleBaseFactory.newRuleBase();
File file = drlFiles.getFile();
FileInputStream fileStream = new FileInputStream(file);
Reader source = new InputStreamReader(fileStream );
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromXml(source);
System.out.println(builder.toString());
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg );
}
catch(Exception e)
{
}
}
}
But there is a problem that the method returns after the statement
PackageBuilder builder = new PackageBuilder();
Please le me know what the problem can be.
Waiting for an early response
Thanks

Re: [rules-users] Problem passing objects to a method via the eval statement
Thank you Mark for the quick reply. I am curious if this is only temporary
or if this is the protocol that Drools is going to use for or statements?
The reason I ask is that i come from a jess/clips background, where or can
be used across multiple classes as shown in my example and it is very useful
when you have two huge rules that are identical except for one LHS class
pattern difference.
Obviously the fix for now is to break up the rule into two rules, but I was
curious if this was only a temporary restriction or if this is going to be
the standing protocol?
I'll also grab the new 4.0.5 branch as you mentioned and give that a whirl.
Thanks again Mark!

Re: [rules-users] Re: Maven compilation mojo?
I have not performed any tests on this, but I'm sure the Drools guys could comment on it as they provide serialized vs non-serialized support in the framework. I would have to think it would decrease initialization time as you're only de-serializing objects vs compiling a rule set. Of course, your build time will increase :) Our main goal was to limit the number (and size) of the jars we had to include in our application as we already had a very large distributable for our application. Some features of the compilation mojo: - Precompiles drls, ruleflow, and dsl into their individual packages - Supports single package being spread across multiple DRL and rule flow files using same package name. - Supports DSL through a specific naming convention (some work could be done here to be a little more flexible) - Supports compression to decrease serialized package file sizes (Currently gzip, could tweak to support other compressions) - Serializes via XStream (could be tweaked to support different serialization mechanisms) Eric On Fri, 2008-03-07 at 16:57 +0100, Geoffrey De Smet wrote: Sounds interesting.

Re: [rules-users] Problem passing objects to a method via the eval statement
Joshua,
The limitation is on binding variables on different fact types on
different logical branches and using them in the consequence. If you don't
use the bindings in the consequence, you are fine.
This is a temporary limitation.

Re: [rules-users] Re: Maven compilation mojo?
Interesting I had no idea something already existed (in some form). While his supports more source type compilations than mine does currently (csv, xls, etc), his requires a bit more configuration than mine does. His requires that you specify which files belong to which compiled unit which can lead to a really noisy pom if you have a very large number of packages and/or source files. This also allows a little bit finer grained control over what source files belong in which compiled unit over my implementation. Mine on the other hand, traverses the identified source directory and programmatically groups together source files with identical package names. This requires less configuration in the pom, however you have less control over how/what goes into a serialized package. It assumes if you have multiple rules identified with identical package names, you want these packaged together. I certainly see merits in both implementations. I guess if this never made it anywhere there's not a lot of need for a pre-compilation mojo.

[rules-users] Ant compiler task?
I see numerous references to the Ant task in the documentation but see no documentation on how to use it. Where can I find some? Google turned up nothing... ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Ant compiler task?
Basically you need to add the drools-ant on your classpath
define your compile task
taskdef name=rulebase
classname=org.drools.contrib.DroolsCompilerAntTask
classpathref=drools.classpath /
And use the rulebase task as the following example
target name=rules
rulebase
srcdir=${eclipsepath}src/test/resources/rules
tofile=${eclipsepath}target/cheese.rules
classpathref=cheese.classpath
include name=*.drl /
include name=*.brl /
include name=*.xml /
include name=*.dslr /
/rulebase
/target
you can see my test XML file here
