Re: [rules-users] CompositiveClassLoader$CachingLoader$load method intermittently hangs

2014-05-15 Thread Steven Williams
We are also experiencing the same problems using 5.x and it is causing us
big problems.

I haven't had time to try it yet but do any developers know whether we
would be safe to change the HashMap the CompositiveClassLoader is using to
a ConcurrentHashMap?

thanks
Steve

 This is observed behavior in

 * mvel2 v2.1.8.Final

 We have an environment that loads around 10 different KnowledgeBases into a
 list.
 Then one-by-one a single StatefulKnowledgeSession is created for a single
 KnowledgeBase, facts are inserted, and then fireAllRules is called.

 Every so often, we noticed that we were getting what seemed to be ininite
 looping behavior for during either insertion time or fireAllRules time.
 When we subsequently re-run the *same* session with the *same*
 KnowledgeBase
 and the *same* facts inserted, it was successful and finished in
 milliseconds (the average for our successful runs).  We have repeatedly
 seen
 this behavior of 1 failure, followed by a re-run that is successful.

 We were able to attach a profiler to several of these hung sessions to
 determine what was happening.  It turns out that in both the scenario where
 we saw a hang up on fact insertion and on fireAllRules call, the thread
 dump
 was the same.

 The stack looks like:

Re: [rules-users] Jetty NoSuchMethodError Lorg/eclipse/jdt/core/compiler/CategorizedProblem

2013-11-26 Thread Steven Williams
I noticed this same error when attempting to use the Run Jetty Run eclipse
plugin with Jetty 6.1.26. Changing it to use Jetty 7.5.1 fixed the problem.
We still use version 6 on our test servers without a problem though so I
just put it down to some classpath issue with the plug-in.

Re: [rules-users] How to use type-safe enums in rule condition

2013-11-13 Thread Steven Williams
We use drools for validation rules in our application. Some of these rules
are dependent on which CRUD operation is being performed at the time, so as
part of our validation aspect we insert a CrudMode enum with the current
action (by annotating the advised method). e.g.

@Validate(validators = BusinessRulesValidator.class, mode = CREATE)
public void create(@DTO SomeDTO incomingDto)

In our rules we can then go:

CrudMode(this == CrudMode.CREATE)

The second way we use it (and this one I don't like so much) is that our
validation aspect runs both before and after a method (PRE and POST). We
use an agenda-group to to indicate which phase a rule should be included
which works fine, however we were finding that some conditions were
relatively expensive which had performance implications. Our solution was
to also include a ValidationPhase enum as a fact and use that to
short-circuit the rules. I reckon there is probably a better way to achieve
this however we didn't spend a lot of time thinking about it.

cheers
Steve

 Granted, you can add any number of attributes to an enum so that it's
 just another way of writing a static set of bean objects. But is there
 a good effect to be had from a pattern that merely ascertains the
 presence of an enum instance
 in the Working Memory?

 Other than this, a pattern like
City( country == Country.USA )
 doesn't require the insertion of the Country enums.

I have traced the problem to org.drools.rule.
JavaDialectRuntimeData$PackageClassLoader.getResources. This returns null
whereas AspectJ expects it to at least return an empty enumeration - hence
the NPE. Interestingly the problem does not occur when running our server,
however we can't upgrade unless our unit tests pass and we can't easily turn
off aspectj for these.

Re: [rules-users] execute particular rules programmatically and dynamically

2011-03-31 Thread Steven Williams
I have actually used this method for the one valid case I have thought of -
unit testing rules.

Steve


2011/4/1 Swindells, Thomas tswinde...@nds.com

  Agreed,

 But if you really do want to you can setup an agenda filter so that only
 the activation for the rule you care about is fired – but I don’t think
 there are many valid cases where this is needed/desirable/appropriate.

 *Subject:* Re: [rules-users] execute particular rules programmatically and

 Why would you want to execute a single rule?

 The logic you'd write to determine which rule to fire should itself be part
 of the rules: So, for example, if you want to validate facts of type Smurf
 then write a rule that matches on Smurf. When you insert a Smurf only
 the rules that match on this will become candidates for execution when you
 call fireAllRules. Perhaps use of a stateless session would simplify things
 so you need not worry about other facts in WM polluting the results you
 expect to see?

 More and more questions are posted here asking how to make individual rules
 execute; IMO the solution is to change your thinking about how Rules Engines
 work.

 If you give your use-case we might be able to advise a better approach.

 With kind regards,

 Mike

 No. The right hand side of a rule (code between then and end) is
 executed whenever there is a set of fact objects in Working Memory
 satisfying the condition. If you insert such a set of facts and call
 fireAllRules(), then it will happen.



  I don't think
 agenda-group or activation-group can do that, right?  Or is it
 possible to create an agenda programmatically ?


 No to both.

[rules-users] KnowledgeAgent Issue

2011-03-21 Thread Steven Williams
Hi all,

I am trying to use a Knowledge Agent in 5.1.1 with a change set with a few
different packages and resource types in it, and I am running into a problem
where it is not adding all the packages. Looking at the code I can see that
KnowledegeAgentImpl.createPackageFromResource has the following code when it
loads a resource:

if (kbuilder.getKnowledgePackages().iterator().hasNext()) {

return (KnowledgePackageImp)
kbuilder.getKnowledgePackages().iterator().next();

}


and KnowledgeBuilderImpl.getKnowledgePackages does the following:


Package[] pkgs = pkgBuilder.getPackages();

ListKnowledgePackage list = new ArrayListKnowledgePackage( pkgs.length
);


and PackageBuilder.getPackages does the following:


for ( PackageRegistry pkgRegistry : this.pkgRegistryMap.values() ) {

Package pkg = pkgRegistry.getPackage();

// add package to array

}


pkgRegistryMap is implemented as a HashMap however so the order the packages
are returned in is not guaranteed. I seem to be hitting this problem.

This is a hard one to create a unit test for so I wanted to check that my
analysis is correct before raising a bug. Perhaps using a LinkedHashMap or
similar would fix it?

Re: [rules-users] KnowledgeAgent Issue

2011-03-21 Thread Steven Williams
I'm not sure whether they were added or not. I noticed the rules weren't
running when I expected them to though, so perhaps not. I have worked around
it by putting all my rules in the same package - luckily I only had about 30
different rule files, but it is a less than ideal solution.

Once I have everything working and checked in on my project I'll test
further to see what is going on.

 Someone mentioned me the problem some time ago. I have a fix for it in my

 The problem is that under certain circumstances, the kagent is reusing the
 same kbuilder to compile all the resources present in a change-set (the
 modifications I have force the agent to use a new kbuilder for each
 resource).
 The only difference between what you are reporting and the problem I'm
 talking about is that in my case all the rules, functions, etc were added to
 the kbase, but all within the same package. No matter the real package
 definition. Is this your case also?

 Please file a bug report and let me know.

[rules-users] RuleFlow question

Hi guys,

I am playing with the OrderExample in drools-examples and was wondering how
I get access in my rules to the parameters that are sent to startProcess?
e.g.

MapString, Object parameters = new HashMapString, Object();
parameters.put(order, order);
parameters.put(orderId, order.getOrderId());
parameters.put(email, emailTextField.getText());
ProcessInstance processInstance =
ksession.startProcess(org.drools.examples.process.ruleset.RuleSetExample,
parameters);

I have access to the ProcessInstance but there doesn't seem to be any clear
path to the parameters.

[rules-users] KnowledgeBuilderConfiguration

2009-01-20 Thread Steven Williams
Hi guys,

It's no biggy but I was wondering whether KnowledgeBuilderConfiguration will
get an addAccumulateFunction method, similar to PackageBuilderConfiguration?
In our project we use Spring to configure Drools, which means we have a
MapString, Class available for accumulate functions, so we could
previously do:

config.addAccumulateFunction(entry.getKey(), entry.getValue());

Now with KnowledgeBuilderConfiguration we had to change the Map to
MapString, String and do the following:

config.setProperty(drools.accumulate.function. + entry.getKey(),
entry.getValue());

which seems like a retrograde step.

[rules-users] Drools 5 Accumulate Function

2009-01-18 Thread Steven Williams
Hi all,

I am converting over to Drools 5 and have run into a problem with
AccumulateFunction. I changed my classes to implement
org.drools.runtime.rule.AccumulateFunction however this causes the
ClassCastException below:

Caused by: java.lang.ClassCastException:
au.com.promedicus.rules.MaxPriceAccumulateFunction cannot be cast to
org.drools.base.accumulators.AccumulateFunction

org.drools.compiler.PackageBuilderConfiguration.getAccumulateFunction(PackageBuilderConfiguration.java:489)
at
org.drools.rule.builder.dialect.java.JavaAccumulateBuilder.build(JavaAccumulateBuilder.java:108)

My guess is this is a bug. For now I will just go back to implementing
org.drools.base.accumulators.AccumulateFunction.

If you put an X or something in the cell (i.e. just don't leave it empty) it

  The action is not being executed. I don't use decision tables
 frequently, but I think that it ignores empty cells and is generating an
 empty consequence for your rule. Usually, you would place the method call on
 the header prototype and the parameter in the cell. So your cell would be:

 | hoover | true |
 | xyz | false |

  The method prototype would be something like (please check the correct
 syntax in the manual):

 brand.setGoodBrand( $param );

  Where the engine would replace $param by the value you write in the
 cell.

  I tried that and it returned false, which doesn't make sense to me since
 the rule firing is to set the value to true, and in the execution the rule
 does fire.



 StatefulKnowledgeSession session =
 kbase.newStatefulKnowledgeSession();

 Product p = *new* Product();

 p.setBrand(hoover);

 session.insert( p );

 *int* u = session.fireAllRules();



 System.*out*.println(u +  many rules fired);

 System.*out*.println(is brand good?  + p.isGoodBrand());



 Here's a snippet of the rule (decision table)





 * *

 CONDITION

 ACTION

 * *

 Product

 * *

 brand

 setGoodBrand(true);

 *Cases*

 hoover match case



 *Brand Check*

 hoover

 And the console returns:



 1 many rules fired

 is brand good? false

Can't you keep the reference to your object while firing the rules?

 MyObject x = ...
 ksession.insert( x );
 ksession.fireAllRules();
 boolean result = x.getBooleanAttribute();

 2009/1/12 Costello, Robert rcos...@searshc.com

 So, how do I access data after the rules fire?

 If one has a rule which modifies a field on an object (a boolean, for
 example), and you want to return the object after the rules are
 complete, how do you do it?

 I tried this using a StatefulKnowledgeSession, getting an object
 collection after the rules fire, but I don't see that this works.

 Also googled the heck out of this and looked in all the documentation.
 I must be missing something, because the docs generally are pretty good.


 Any hints?

Re: [rules-users] having counter in drl

Globals should only be used for data that is constant over the life of the
working memory, which is not so in your case.

Maybe you should just use a fact counter. If you don't want to affect your
code you could insert it in a separate rule.

Re: [rules-users] Re: Is this scenario suitable for using Drools?

2008-04-23 Thread Steven Williams
without knowing how you are accessing the database your two algorithms come
down to something like:

Alg. 1
max(select max(p) from y, select max(t) from z)

Alg. 2
select min(p) from y + select min(t) from z

which is basically the same as what Michael has proposed.

Personally I think if you are already using Drools then this would fit, but
it wouldn't seem like enough of a reason to introduce Drools on its own.

Re: [rules-users] Modifying fact object during rules execution

2008-04-13 Thread Steven Williams
You could then have a rule that checks not (Currency type == USD) and a RHS
with that inserts a new converted amount. If your conversion is rules-based
then just have a rule per currency conversion.

Your processing rules could then act on the converted amounts.

 Hi,

 Currently we have a rule defined like this
 When
  Currency value = 300
  Currency type = USD
  Condition 3 = something
  Condition 4 = something
 Then
  do this

 If the input values are not of the same currency then we need to do a
 currency conversion and then evaluate the above rule. For example if the
 input value says Currency value = 250 and currency type = Euro. then we
 need
 to convert the currency value from Euro to USD and then execute the rule.
 Is
 this possible by using functions on the LHS. If possible is there a better
 way to do this as we are currently looking at 10,000 rules to go through
 this routine.

 The workingmemorylogger wants to show the value of the variable iep even
 if
 my 'param' is not present in the working memory !

 Is it a bug ?

 thanks for your help,

Re: [rules-users] Feature request

  This is a feature request, or if the feature already exists, a request
 that somebody let me know :)



 I have a set of rules that heavily depend on regular expressions to
 operate.  The regular expression is matched on the LHS of the rule, and then
 passed to another object for additional processing in the RHS of the rule.
 We're looking at a few hundred rules here.  Here's the problem – because of
 needing to use the regexes twice, I have stored them in a separate container
 class as public static final String variables; however what we really want
 to do is to be able to make a modification to either the regex or the rules
 themselves, hot deploy the changes to the rule, and have everything work.
 We specifically do not want to have to try hot-deploying or re-compiling
 classes due to the potential issues that can arise.  As it stands now it's
 looking like we are going to have to endure a pretty heavy maintenance
 burden by changing the rule, hot deploying, then later in the evening
 redeploying the java code and rebooting the server whenever we make a
 change.



 The ideal solution for this problem would be if we could set
 package-scoped variables in the .drl file, outside of the rules.  For
 example, at the top of the drl file, below the import statements, if we
 could write something like the following:

  let String THIS_STRING = this regular expression;



 and then in the background when the rule classes are generated, have them
 be declared as static final/constant variables.  This way they could be used
 on either side of the rule, but if a change is made the RuleAgent will see
 that and overwrite the old version of the rule package and fact processing
 would be able to continue uninterrupted.



 If anybody has any suggestions on a work around, I would be appreciative.



 Oh, and thanks to everybody for helping me get the RuleAgent to work :)

 1. Decision does not support Agenda Groups
 2. Using a fact; to hold the evaluated result from a DT can pass it from a

 variable.

 (Parent) DT - Condition 1, condition 2, Condition 3 (Actually result of
 Child
 DT)


 (Child DT)
 ... The relation is maintained using decision variables.

 This relation works perfenctly good (been working for 3 months now), but
 issue
 is it creates a Sort of a Tree (with each node a DT); in shich I cannot
 fire a
 common set of rules from Any Node.

 As an alternative; I'm suggesting to the client to write replicated DT's
 for
 each type of employee instead of 1 generic DT.

 Can anyone help?

 I've been begging for agenda Groups in decision tables but I guess you
 guys are
 tied up. So at a design level can you suggest a work around?

No - you can use any java object as a fact, so both of your classes are
fine. For instance you could do:

when
  Car($p: paint)
then
  System.out.println($p.getName());
end

and using MVEL you could do:

when
  Car(paint.name == red)
then
  ...

 public class Car

Re: [rules-users] How to stop a rule from firing?

2007-06-21 Thread Steven Williams

One simple way is:

 [when] condition3 = not condition2  \\someCondition;
 [then] assert the Object2 into Working Memory;

 [when] condition4 = not condition2  \\someCondition;
 [then] Set the Error Message.

Generally you should keep your rules independent of each other.

If this is just a naive example of a more complex problem maybe you should
look at the RuleFlow (in v4) or agenda groups.

  [when] condition3 = \\someCondition;

By requirement is when the condition2 is satisfied, the error code should
be
set and the following rules should not fire. If the condition2 is not
satisfied, it goes to the condition3 and condition4. If condition4
satisfies, it should set the error code and stop firing the rules again.

I dont know how to stop the rules from firing after the error code is set
in
the condition2.

Can someone help me on this issue.

So I changed the rule table to simply say:

This throws:

When I googled on this error, most of the occurrences appeared to be

It blows up because it knows that setAnswer is not a static method, which
tends to tell me that it found my class.



I think I've parroted the example exactly and so I'm confused as to where

2007-04-05 Thread Steven Williams

J2EE does not allow File I/O so it may be that your app server does not
allow it by default and you need to give your application permission to do
it. This would generally be done in a policy file (in WebSphere it is
was.policy).

Re: [rules-users] conditional insert of 'exist' or 'not' keywords in decision table s

2007-02-19 Thread Steven Williams

Hi Vlad,

There is a very basic wiki page on it
(http://wiki.jboss.org/wiki/Wiki.jsp?page=DecisionTableTemplates
).

In terms of the functionality you mention you have your data having
knowledge of the rule templates whereas the current implementation is such
that the data has no knowledge of the templates. You can apply multiple rule
templates to the same data however (as in
ExternalSpreadsheetCompilerIntegrationTest):

   final ExternalSpreadsheetCompiler converter = new
ExternalSpreadsheetCompiler();
   final List listeners = new ArrayList();
   ExternalSheetListener l1 = new ExternalSheetListener(10, 3,
/templates/test_pricing1.drl);
   listeners.add(l1);
   ExternalSheetListener l2 = new ExternalSheetListener(30, 3,
/templates/test_pricing2.drl);
   listeners.add(l2);
   converter.compile(/data/ExamplePolicyPricing.xls, InputType.XLS,
listeners);

This example assumes two sets of data in the one sheet, however they could
both have been applied to the same set (ie. the second listener could also
point to row 10, column 3). Would that accomplish what you need?

Steve

 Thanks, Steve. That really seems to do the trick. Are there any wiki

code  unit tests?



I also wonder what other functionality the new templating engine has? Is
it possible to define different 'types' of rules in the same 'rule' template
and refer to these types from 'Excel' data fields (eg, have one column per
rule where you can refer 'rule template XXX' from drl file; this value can
override some default value for example). If not, how such situations can be
handled? (ie, when one needs several type of rules driven by the same data?)



Thanks,

Hi Vlad,

With the new decision table handling you could use the following template
to do it:

Given a table as follows:

exists, 21, 25

, comprehensive

not, 64, 100

exists, comprehensive

the following template does what you want:

template header
driver[]
policy[]

package This_is_a_ruleset;
#generated from Decision Table
import example.model.Driver;
import example.model.Policy ;

template Driver policy
driver
policy

rule driver policy $row.rowNumber$
when
$driver0$
Driver(age = $driver1$, age = $driver2$)
$policy0$
Policy(type = $policy1$)
then
//do smth
end
end template

the code to call it was:
public void testColumnKeywords() {
final ExternalSpreadsheetCompiler converter = new
ExternalSpreadsheetCompiler();
final String drl = converter.compile( /data/TestWorkbook.xls,
/templates/test_keywords.drl,
  InputType.XLS, 1, 1 ); // DT

Re: [rules-users] Convert logic to DRL rules

2007-02-17 Thread Steven Williams

In trunk I think you can use connective constraints:

$a : Person(age  35 |  25, zipCode == 23546 | == 68590)
then
$a.setStatus(KT);



On 2/18/07, Bill Zhang [EMAIL PROTECTED] wrote:


Hello,

I am a new Drools user trying to convert the following simple logic into
DRL:

IF (Person.Age  35 OR Person.Age  25) AND (Person.ZipCode = 23546 or
Person.ZipCode = 68590)
THEN
Person.Status = KT;

I found that it is not easy to convert the above logic into ONE DRL rule.

I tried something like this

when
$a: Person(age35) or Person (age25)
$b: Person(Zipcode==23456) or Person (ZipCode == 68590)
$c: $a and $b
Then
$c.setStatus(KT)

But looks like I can not use
$c: $a and $b
becaue in Drools, you can only bind variable to column, not to other
varaibles.

Please advise how to do this. I would imagine this should be quite
simple, maybe I missed something quite obvious.

I know that I can write custom Java method to do this, but if I do
that, I suppose I lose the power of RETEOO pattern matching (pattern
resuing,
etc.). So I prefer not to do that.

I also understand I can break the above logic into 4 rules and that
would be quite easy, but our business user is not used to think in
that way. Also, we have more complex logic than the above. So what I
want is to see if there is a way to convert this
kind of logic in ONE DRL rule.

Thanks in advance.

Re: [rules-users] How to generate rules from decision tables whereLHS has no field constraints

2007-02-15 Thread Steven Williams

Hi Martin,

The decision tables on trunk do what you want and should be available in the
3.1 release (I think). The new code separates the rule template from the
data and is more flexible than the current version. There are some
integration tests that demonstrate how to use it (have a look at
ExternalSpreadsheetCompilerIntegrationTest).

For your example you would use the following template:

template header
cheese
smell

package com.cheese;

template calculateSmell
smell
rule calculateSmell $row.rowNumber$
 when
   cheese:Cheese()
 then
   cheese.setSmell($smell$);
end
end template

I will put up some further doco on the wiki tonight.

cheers
Steve


On 2/15/07, Martin Weidner [EMAIL PROTECTED] wrote:


Hi Michael,

Thanks for  your reply.

Leaving a cell empty results in the condition not being added to the rule
at all. Which is fine, cause then you're more flexible in grouping rules
with different conditions together in one decision table
I actually found a way yesterday, which seems to me more like a
workaround. But it works:

| 1 | RuleTable calculateSmell  |
| 2 |CONDITION| ACTION  |
| 3 | | cheese  |
| 4 | cheese:Cheese() | setSmell($param); |
| 5 | for every cheese| set smell to stinky |
| 6 | somevalue   | stinky  |

By declaring the variable not in the row right underneath below the
CONDITION cell, but in the row where you normally declare the conditions (
i.e. second row underneath the condition row
AND putting in some random value in the cell, that holds the parameter
value, you can generate the desired rule:

#From row number: 6
rule calculateSmell_6
when
cheese:Cheese()
then
cheese.setSmell(stinky);;
end

Leaving out the parameter value results in the when line being blank, so
you gotta fill in something.
I can live with that, but it seems to me more like a workaround, so I
would be kinda curious whether there is (or will be) an official way of
achieving this
Best regards,
Martin

I am pretty sure that all rules in all agenda groups run pattern matching

default behaviour). You can see this by using the audit logging feature.

Re: [rules-users] Rules to detect states in an object graph?!?

2007-01-23 Thread Steven Williams

Hi Michael,

To do the opposite approach (where the relationship is navigable from the
parent only) you can use the following:

when
   c : Child ( age  18 )
   Parent ( children contains c, type == SMURF )

Of course this requires either

  - the child object in the children collection to be the same as the
  asserted child object or
  - the equals/hashcode method to be implemented appropriately in Child

//Java code

This requires that the parent-child relationship is navigable from the

What other approaches does anyone else use to implement rules that span
related objects?
