Re: [rules-users] Data comparing in CONDITION column decision table
I inserted Account column with values that are always true. Works fine. :) Will try the same with 5.3 .

As a workaround, re-insert the Account column and use a redundant condition that is certainly true for all facts. I'll have to look into this. -W On 15/03/2012, Sumeet Karawal wrote: > Hi Wolfgang > > any other way to achieve this.

Re: [rules-users] Data comparing in CONDITION column decision table
After doing the changes, its taking the rules as:
rule "Discount_10"
when
$a:Account(type == $a.getType(), accno == 1001) $c:Customer
then
$c.setDiscount(1);
end
and if I put it as $a: Account() $c: Customer(), it takes the rules as:
rule "Discount_10"
when
$a:Account(type == $a.getType(), accno == 1001) $c:Customer()
then
$c.setDiscount(1);
end
Both these throw error..
neither putting the $c:Customer before $a:Account is getting executed.

[rules-users] Decision table multiple sheets...
Hi,
I am having my rules in a Decision Table (.xls)
There I have 3 sheets for rules.
Like in Sheet1 there are two Rule Tables... In Sheet2 there are 2 and in
Sheet3 there is only 1.
When I am creating the knowledgebase and firing rules, the rules that are
in the Sheet1 are getting fired. But the rules in other sheets are not
getting fired.
When I convert them to String to check using this code :
String str = DecisionTableFactory.loadFromInputStream
(ResourceFactory.newClassPathResource
("com/sample/MemberDiscountRules.xls").getInputStream(), dtconf);
System.out.println(str);
I can see the rules that are present in Sheet1 only.
Please anybody help me on this. How can I get the rules in other two sheets
to get fired.
Also how can we fire the rules of only a particular Rule table in the
decision table.
Thanks & Regards,
Sumeet

Sumeet, Marco, Sorry I didn't want to be harsh with my response :) Cheers 2011/11/14 Marco Rietveld Summeet (and others), As mentioned, this is indeed a drools (user) mailing list. The proper mailing lists for jbpm (3, 4 or 5) are: jbpm-us...@lists.jboss.org (for these types of questions) jbpm-us...@lists.jboss.org (for developers and people who look at jbpm code/internals) Most of the jbpm core developers monitor both lists. Thanks, Marco 11/14/2011 02:00 PM, Marco Rietveld: Hi Summeet, jbpm 3.2.x works with jBoss AS 5.1 -- and obviously also with Drools 5.3, since there's no overlap between those two versions of jbpm and drools. I'm not sure if Drools 5.3 works with jBoss AS 5.1, although I think it does. There is a difference between jbpm 3.2.8 and the supported version of jbpm 3.2. It's hard to quantify the difference exactly, but since late 2009 when 3.2.8 was released, a number of bugs have been fixed in the supported version. . Marco 11/11/2011 10:39 AM, Sumeet Karawal: Thanks Thomas No, I am a little confused which version to use. I visited the site http://sourceforge.net/projects/jbpm/files/jBPM%203/. Here the maximum downloads are for v 3.2.2 and the latest among these is v3.2.8. It would be very helpful if you could suggest me which one to use among the versions 3.2.x.

Re: [rules-users] Regarding BPEL
Thank you. This was really helpful.

The version 2 of the standard defines the language and the execution semantic for defining Business Processes with a wider scope than BPEL. Of course that BPEL and BPMN are not the same, but I think that you can achieve most of the things that you want to achieve with BPEL with BPMN (I'm not sure what are you trying to achieve, but we can discuss that in another thread). In the case of BPMN, Drools is not the one responsible for the process execution and jBPM5 is. Where jBPM5 is right now a former module of the Drools Project. jBPM5 provides you a generic process engine capable of understanding more than one process definition language, but right now the project is focused on running BPMN models. In other words, jBPM5 is capable of running BPEL process, but right now the parsers for the BPEL models are not in place. Most of the BPMS vendors are adopting BPMN as a defacto notation and I think that for that reason jBPM5 is only focused in this language now. Hope it helps..

Is jBPM compatible with BPEL or is there anyway to have BPEL functionality with jBPM. jBPM creates the process using JPDL. Is it better in someway or the other than BPEL ?

Hi,
I am trying to create rule in Guvnor and runnig it in Java Application on
Eclipse.
I have gone through the mortgages example provided in the distribution. I
am not sure that I am doing it correctly The steps I did are as follows :
1) Uploaded a POJO jar in Guvnor
2) Created a rule for checking the value of POJO data member
3) Built the package
4) Downloaded the ChangeSet.xml provided
5) Imported that ChangeSet.xml in Eclipse project under com.test package.
6) Created KnowledgeBase and fired the rules
My POJO :

Thanks Tihomir. I have installed the designer for Guvnor and have started referencing to the links provided by you. But I have small query : In the rule flow we could design an order in which the rules would be fired. Will that be possible using BPMN 2.0 process? Aslo if the user wants to make the changes to the flow, then can these changes be done on the fly?

It is the default format in jBPM5 and our web tooling support focuses on creating/editing BPMN 2.0 processes. To get started with this, please reference docs: https://hudson.jboss.org/hudson/job/jBPM/lastSuccessfulBuild/artifact/jbpm-distribution/target/jbpm-5.2.0-SNAPSHOT-docs-build/jbpm-docs/html/ch10.html and several blogs+videos: http://blog.athico.com/search?q=oryx. If you use the jBPM-installer ( http://docs.jboss.org/jbpm/v5.1/userguide/ch03.html) it will help you set everything up for the demo setup. I would strongly suggest converting your processes to BPMN 2.0 since .rfm is considered legacy at this point and will AFAIK receive no more development attention. You are also always welcome to ask questions regarding the jBPM Web Designer on IRC (http://www.jboss.org/jbpm/irc) as well as user forum ( http://community.jboss.org/en/jbpm?view=discussions).

If you don't show your code we can't tell you what is wrong with it. So I
think what you may have to do is
when
$someObj: SomeClass() # matches each WME of SomeClass
eval( $someObj.getValueBoolean("abc"))
then
There is not much to be gained by using a DRL function; it would have to be
called like
eval( someFunction( $someObj, "abc" ) )

The default getters and setters are not being used in the Application.
The
value that is being returned by the method needs to be checked in
the .drl
file.
There are different Java classes with these kind of methods. Where the
string and integer value is also returned. I have gone through the
documentation for Drools-Expert but have only found the implementation
for
the method in the consequence part, i.e., the then part.
This is how I tried:
importing the class
in when
binding the a variable to the Class name suppose $c
eval ($c.getValueBoolean("abc"))
then
System.out.println("the value is true")
It didn't work this way.
I tried by another way like :
creating a function in the .drl itself that calls the method of that
class
and returns a value
then calling this drl function in the when part and carrying on.
It would be very helpful if some body could let me know how to do this in
the .drl.

// returns a boolean value
}
The default getters and setters are not being used in the Application. The
value that is being returned by the method needs to be checked in the .drl
file.
There are different Java classes with these kind of methods. Where the
string and integer value is also returned. I have gone through the
documentation for Drools-Expert but have only found the implementation for
the method in the consequence part, i.e., the then part.
This is how I tried:
importing the class
in when
binding the a variable to the Class name suppose $c
eval ($c.getValueBoolean("abc"))
then
System.out.println("the value is true")
It didn't work this way.
I tried by another way like :
creating a function in the .drl itself that calls the method of that class
and returns a value
then calling this drl function in the when part and carrying on.
It would be very helpful if some body could let me know how to do this in
the .drl.

Thanks for the reply. Actually I have to work on an Application that is based on Java 1.4 and there haven't been any major changes in the code, currently business logic is managed through Java code only.

Re: [rules-users] Exposing rules as services
Hi, Thanks Xinhua!!! Here I am able to get that using drools server, we could expose the knowledgebases as RESTful services, and those could be consumed by the Application. As in the normal application, we create a Knowledgebase, then session and insert facts,. after that we fireAllRules(); So will the procedure be same in this case, to insert fact,creating knowledgebases and firing rules. Also can't we expose the rules as SOAP services? Actually I have never come across using rules as services. But in the new implementation I have this requirement. So, I am totally confused on how to go ahead, how to actually do this. Thanks for the help...

Re: [rules-users] Facing Problem in BRL
Hi,
I am now able to run the examples (by removing the commented statements in
the drools.package file). Thanks a lot for the help.
But how can we create more rules in a brl . Is it possible to create more
than one rule in a brl
as we do in the drl file or do we have to create different brl files for
different rules.
Also is there a way to use the brl directly as we use drl.
Like using :
builder.add (ResourceFactory.newClassPathResource("com/rules/discount.brl"
),ResourceType.BRL);

Re: [rules-users] Facing Problem in BRL
Hi All,
I removed the commented lines from the drools.package file. Its now working
fine.
Thanks a lot!!!
I was using the brl for the first time, so didn't know that the rule name
was getting commented out.
I used the same code to convert it into drl and pass it to package builder.
Isn't there a way that we can use the ResourceType.brl instead of
ResourceType.drl .
like : builder.add (ResourceFactory.newClassPathResource(
"com/rules/example.brl"),ResourceType.BRL);
Also in a drl we can write many rules, but when we use brl do we have to
create different brl files for different rules. I mean can we have more
than one rule in a brl file.

Can you write the outputDRL to System.out and check if the generated DRL
syntax is correct ?
System.out.println(outputDRL);

You have to put a lot of data in memory cache (ehcache for example) as the database is the the weak point in concurrent mode. As for drools, it was running on a simple bi-core server with 4 GB of ram and it could handle 10 concurrent calculations without problems. The total calculation time all inclusive (network connection, database, etc) does never exceed 2 seconds with about 1 loyalty rules for 80 products. The biggerst shop they have has more than a 100 cash machines that can be all open on a saturday afternoon. With a modern server (4-core hyperthreaded=8 cores) and all the rest and even with more ram (= place for data caching) you can even do much better. Hope it helps Regards Nicolas Héron 2011/4/27 Michael Anstis If you use a stateless session per transaction you should generally be OK. How much lag you're likely to encounter is a much harder question to answer: how well does your database retrieval scale, would this present an issue before the rules engine?

Re: [rules-users] Drools Performance
Thanks Michael for the help. But, is there any benchmark or a rough figure like number of hits or number of rule fired per minute, for normal performance. Regards, Sumeet Karawal Mailto: sumeet.kara...@tcs.com From: Michael Anstis To: Rules Users List Date: 04/27/2011 04:13 PM Subject:Re: [rules-users] Drools Performance Sent by:rules-users-boun...@lists.jboss.org If you use a stateless session per transaction you should generally be OK. How much lag you're likely to encounter is a much harder question to answer: how well does your database retrieval scale, would this present an issue before the rules engine? The rules engine is "just a POJO library" the overall scalability would IMO depend upon your application's architecture.

Re: [rules-users] Fw: Some Querries on Drools
Thanks a lot Randhish!!! Stateful sessions will have to be disposed. But what if the sessions are taking too long, same with the case of stateless sessions, then what to do in that case. Also in the multi- threaded environment, if I have 10 - 100 Ks of threads, will the rule engines performance be still better.

I don't think Drools will cause your application to crash if you ensure 1. You develop rules that will not result in infinite loops. 2. Dispose sessions if you are using Stateful sessions. Basically, you would want to create the Knowledge base once i.e. during application startup. You will create a new Session (not an expensive operation) for every request. In this scenario it will be better to use stateless sessions as you do not have to worry about disposing them. However, if you want to use statefull sessions, you might want to write a set of wrapper classes that provide api's to manage the statefull session and execute rules. Developers will only be allowed to access api's that execute rules and will not have access to api's that create and dispose a session. To you next question on making changes to rules, You have to create a KnowledgeAgent that checks if the rule resource has been modified at configured intervals. The rule resource (drl,pkg etc) can exist on the file system or you want to try to configure rules in guvnor. Guvnor is a GUI tool that allows you to manage rules.

Re: [rules-users] How to use for loop in drools!!!!
Thanks Esteban!!. I got you point. But how to make the rule to run
according to a condition, in a loop.
Also, how can we trigger the firing of one rule from another rule. Like
when the Condition part of a rule satisfies then, in the Action part a
particular rule is triggered and after that the control resumes to the
previous rule, just as we do in nested if else statement.

Sent by:rules-users-boun...@lists.jboss.org
Drools is an inference engine and it let you express your knowledge using
rules.
A rule has 2 parts: CONDITION par and ACTION part.
The CONDITION part is expressed in a drools' proprietary syntax, but in the
ACTION part you can use plain java code.
What you have described looks like an action that needs to be executed when
certain constraints are meet.
So, in your case, you can just write those lines in you action part. They
should work fine.
I recommend you to read the documentation:
http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-expert/html_single/index.html

Hi All, Could you please help me on this. I am trying to create rules in Guvnor and then using those in eclipse. These are the steps that I am doing 1) I have created a POJO in eclipse 2) Exported as .jar and uploading it in Guvnor under a package. 3) I have created rules also in Guvnor and the test scenario there is also working fine. 4) I build the package and the binaries get generated. But I am not getting how to use those rule in my Java Application running on Eclipse. I have gone through the user guide and forums also but not getting the concrete solution for this. >From somewhere I got the following code : KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent ( "MyAgent" ); kagent.applyChangeSet( ResourceFactory.newUrlResource( url ) ); KnowledgeBase kbase = kagent.getKnowledgeBase(); But how to work according to it. Which url I have to give here, also I am not able to locate the changeset.xml. Also what should I write in the .properties file and how to refer to that.
