[rules-users] Adding two numbers
I have two properties on my class that I'd like to add together and compare results. I'm trying: when stub:PaymentStub(daysJuror + daysPanel 0) But this throws an error. Either daysJuror or daysPanel work, but adding them together doesn't. Isn't there a way to do this? Thanks!

RE: [rules-users] single binding for or CE flagged by compiler
Not getting into whether this is a bad practice, the only language I've
ever seen support this syntax is COBOL. Every other language I've worked
in (and there are many) do not support this technique, so it seems
reasonable that this syntax should be disallowed in drools as well.

Subject: Re: [rules-users] single binding for or CE flagged by compiler
This is an old discussion. Single binding on or is a non-orthogonal
special case on the language syntax that was introduced in the early
days when we only had infix CEs. When we started to support prefix CE,
the special case was not updated, and as a result, the single binding
works only with infix.
IMO, this syntax promotes bad practices and should be disallowed.
Although, some people like it and it is still in there. Just to clarify
why I think it promotes bad practice:
* When you have the same object type for all the patterns inside an or
group, you should be using constraint connector ||, not the or CE.
Using your example:
$t : Trigger( fa == 1 || == 2 ) // or any variation of the syntax.
This keeps the network smaller and prevents unexpected behavior when
the constraints are not mutually exclusive and in some cases people
forget that the rule will fire once for each logical branch when using
or.
* If the object types are different, then you can't use single binding
anyway:
$o : ( Cheese() or Wine() ) // this will lead to ClassCastExceptions on
the usage of $o.
So, I really think that the single binding or fulfilled its purpose
on Drools 3, when we didn't had all the flexibility in the language we
have today. But now, the only thing it achieves is promoting bad
practices.
Just my 0.02c.

As far as I know, this should work:
package orel;
import orel.Main.Trigger;
rule ror1
when
$t : (or Trigger(fa == 1)
Trigger(fa == 2))
then
System.out.println( fired + $t.getName() );
end
This is what Drools-5.0.0 kbuilder.getErrors().toString() returns:
[5,11]: [ERR 102] Line 5:11 mismatched input 'Trigger' expecting '(' in
rule ror1 in pattern or[6,14]: [ERR 102] Line 6:14 mismatched input
'Trigger' expecting ')' in rule ror1[6,30]: [ERR 102] Line 6:30
mismatched input ')' expecting 'then' in rule ror1
Shouldn't toString() insert line ends? As it is, the result is pretty
much useless.
This works:
rule ror1
when
(or $t : Trigger(fa == 1)
$t : Trigger(fa == 2))
then
System.out.println( fired + $t.getName() );
end

It seems you are using a good strategy to do your tests. But still, it is difficult to explain why one is slower than the other without seeing the actual test code. This is because all the engines have stronger and weaker spots. Just to mention one example, some engines (not talking specifically about drools and jrules, but about all engines) implement faster alpha evaluation, others implement faster beta (join) evaluation, others implement good optimizations for not() while others may focus on eval(), etc. It is up to the point that when comparing 2 engines, one performs better in hardware with a bigger L2 cache while the other performs better in hardware with a smaller L2 cache. So, best I can do without looking at the actual tests is provide you some tips: 1. First of all, are you using Drools 4.0.7? It is very important that you use this version over the previous ones. 2. Are you using stateful or stateless sessions? If you are using stateful sessions are you calling dispose() after using the session? If not, you are inflating your memory and certainly causing the engine to run slower over time. 3. Are you sharing the rulebase among multiple requests? The drools rulebase is designed to be shared and the compilation process is eager and pretty heavy compared to session creation. So, it pays off to create the rulebase once and share among requests. 4. Did you disabled shadow facts? Test cases usually use a really small fact base, so would not be much affected by shadow facts, but still, disabling them improves performance, but require some best practices to be followed. 5. Do your rules follow best practices (similar to SQL writing best practices), i.e., write the most constraining patterns first, write the most constraining restrictions first, etc? Do you write patterns in the same order among rules to maximize node sharing? I guess you do, but worth mentioning anyway. Anyway, just some tips.

RE: [rules-users] Help in using drools
That would be one way to accomplish this. For your situation, though, I would use a stateless session since your servlets are stateless. One of the things I'd like to see changed in drools is that, while it does complicated processing and returns complex answers very well, it's difficult to return simple answers. I would like to see methods like fireRulesReturningBoolean kind of thing, but it would require a paradigm shift in the rules themselves. Alas! Anyway, I think that's how I'd handle it. I also construct wrappers around the basic data types to receive these answers. I wish Sun would implement the bean interface for Integer, Long, Character, String, etc. It would certainly be simple enough for them to do, and then we could just use those to hold the values coming back from our rules. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stelarinc Sent: Thursday, May 08, 2008 6:03 AM To: rules-users@lists.jboss.org Subject: [rules-users] Help in using drools Hi, I would like to use drools in my application.

Here is my situation. I am creating a web-based application which requires me to run certain rules for certain page. What I need is to pass all the information accumulated from the pages and pass it through a rule engine. Each rule will check the information and return string message(s) to the caller. Does drools fit in this requirements? From what I understand, I can create a stateful session, passing the information to the rule engine. But when I need to return the result, how do I do that? Do I pass an empty String List into the rule engine, and each rule will add the message to the List if there is an error? Thank you.

No, really, java uses the valueOf methods internally to try to convert the
object specified (a String) into an Integer so it can do the comparison. You
can't do selected == 0 - 50 because 0 - 50 is a String and you cant
compare it to an Integer.
So what are you trying to do? If you want selected to be in the range
between 0 and 50 inclusive, then you need to change the heading in your
decision table. Here's an example:
daysBeforeSummons = $1, daysBeforeSummons = $2
and then you specify the data in your column as 0,50.
Good luck!

I don't understand why Drools tries to convert to Integer something which is

Here is the rules code.
rule setCalculateRate_11

The CalculatedRate field is a java.lang.Integer object.

RE: [rules-users] Basic questions about rule deployment
Just a note about URLs. URLs will automatically do base 64 encoding, which primarily means that all spaces are replaced with %20%. If you are using a URL to represent a file, make sure you test it with a file that has spaces somewhere in the path. I just learned this the hard way. You may need to convert your URL to a URI. Good luck! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fermion Sent: Thursday, October 11, 2007 5:29 AM To: rules-users@lists.jboss.org Subject: Re: [rules-users] Basic questions about rule deployment Thank you very much! I followed your advice and created URLs for my .drl and .dsl files. Then I created a new URLClassLoader instance with these two URLs. Finally I assigned this class loader to my packager builder using: myPackageBuilder.getPackageBuilderConfiguration().setClassLoader(myURLClassL oader); Absolute path names seem to be Ok, as long as one uses file: as a prefix to the URL string. I plan to use a config file to specify the locations of my rule files (dsl and drl). The location of the config file itself will then be defined by a command line argument.

[rules-users] Assigning variables in decision tables
Mark, You made a comment on my JIRA that I thought I'd post here for discussion: Mark Proctor commented on JBRULES-1155: --- anAnwer is a method/function that returns a boolean? Must admit I don't understand what you are trying to do there. Anyway if all you are trying to do is assign the results of a function/method call then why not just use an = assignment? BooleanAnswer = anAnswer(anAnswer.setAnswer(true)); Any valid java can used. What I'm really trying to do is simply return a boolean from a set of really complicated rules in my decision table. I run through the rules and if it passes, I return true. The reason I didn't do what you suggested above is b/c there is no documentation to suggest this is valid syntax and, after several postings to this list, no one responded to my requests on how to do this assignment. So, how do I do an assignment in a decision table to simply return a boolean? Otherwise, can you explain the syntax you posted to me. This doesn't look like any Java I've seen and I can't make heads or tails of how it should work. Thanks.

[rules-users] NPE on DecisionTable rule
Hey, gang!
I have a decision table that generated the following rule:
{other rules removed}
#From row number: 19
rule postponePart_19
when
PoolInfo(courtLocation == 101)
PoolInfo(statusCode = 0, statusCode = 2)
PoolInfo(numberFta 1)
PoolInfo(numberOfDeferralsPosted 2)
PoolInfo(daysBeforeSummons= 2, daysBeforeSummons= 999)
then
answer.setAnswer(true);
end
I call these rules with the following code (I build the ruleBase at the
beginning in the factory method to be used by everything:
StatelessSession session =
participantRuleBase.newStatelessSession();
//now create some test data
PoolInfo pool = part.getActivePool();
BooleanAnswer answer = new BooleanAnswer();
Object[] rules = new Object[]{pool, answer};
session.execute(rules);
return answer.isTrue();
BooleanAnswer is simply a convenience object I created to store the answer
from the rules. (If anyone has a better way to do this, please let me know.)
I got the following stack trace:
java.lang.NullPointerException

RE: [rules-users] Rule compilation errors under heavy load
Couldn't you use yield() to generate a context-switch?

The test is not guaranteed to fail if there are thread safety errors, just very likely to fail (don't know if this is acceptable for you). Initially, I wrote a test which guaranteed that calls to the addPackage() and getPackage() methods were interleaved by different threads, but, annoyingly, this test passed.

I did use this originally, but for some reason it generated fewer errors than using some arbitrary sleep values. At the time, I explained this to myself as follows: yield() means that context switching happens at well-defined points, whereas when there are lots of sleeping threads waking up at arbitrary moments wanting to be run, context switching happens more randomly.
