Re: [rules-users] Conversion from Normal Decision Tables to Web-Based Tables and vice-versa
Hi Barry, Sorry for replying pretty late to this e-mail, there was something wrong with my subscription to the list. We did not pursue this further as we got our clients to agree on using the Excel based decision tables(In fact they wanted Excel, but with more validations to ensure that someone does not make a mistake while entering rules!!). Overall, it looked like all we needed to do was to somehow convert our excel columns into the XML of the decision table and put it in via WebDAV. If you had made progress on this, please share it with the list for future reference.

Re: [rules-users] Multiple worksheet decision tables
Hi, I had written some code for this a while ago. But, basically Drools uses jxl for compiling decision tables. You can also use JXL. It has an API that gives you all the worksheet names, which you can then pass to the compiler one by one to compile all your decision tables. From memory it went something like this (Import jxl***.jar) Worksheet w=new WorkSheer(new File(filepath.xls)); w.getSheets(); This should get you a list of sheets.

RE: [rules-users] Help on using Drools with embedded objects
There were a couple of ways mentioned in the Drools documentation for 4.0.7.
1) Eval is the Quick way to get this done. This does have a performance
penalty though
2) Read up on using the - operator that allowed you to go deeper into the
object hierarchy.
3) A third way which I used was to write setter and getter methods for
fields I needed in the rules condition in the root class itself. Since Drools
introspects on setters and getters this seemed to work.
To take an example, if I have a class as follows:-
Class B{
int a;
public int geta() {};
public int seta() {};
}
Class A {
B b;
public int getA()
{
Return this.b.geta();
}
Public void seta(int b)
{
this.b.seta(b);
}
}

Hi,
I am planning to use Drools - JBoss Rules Engine. My requirement is to disburse
mails from my application to different groups based on various criteria. I want
to use Drools here.
My object structure is as follows:
class A{
String B = ;
B b;
C c;
}
Hence Obj A has embedded objects within it, and obj B and C further has
embedded objects.
class B {
String X;
Z z;
}
class Z{
String t;
String s;
}
The decision on sending the mails based on the fields in embedded objects of A.
I pass instance of A to Drools
Format of drl file:
package...;
import ..;
rule Test
when $a:A(B(Z(s == testvalue)))
then
$a.setSomething();
update($a);
end
I wanted to know if this (accessing fields in embedded/child object) is
feasible with Drools.
I get an error saying UNable to compile myfile.drl when i try to fo this.
Could some one look into this issue and let me know the reason for this ?

RE: [rules-users] Drools Performance
I can only add one thing to the answer. I don't have performance metrics available, though I did some QD tests with 15000 rules and the speeds I got for the kind of processing I did (1-3 seconds) were really good. The downside was the Permgen memory space usage which was pretty high and we are still grappling with that problem. Mark had suggested that I use MVEL instead of the Java Dialect(which we could not do due to a time constraint) to reduce this usage besides we are now migrating to Drools 5 where we hope this has improved.

[rules-users] Guvnor Web Based Decision Tables

We are doing a drools implementation with quite a few decision tables which we think can be best served by using the web-based tables. However, we need to migrate data/masters from an older system and would need some kind of utility to populate the web based tables initially and then let the users do the modifications/changes.

RE: [rules-users] Not looping the rule when more then 1 valid match is found
I wonder if you can use a Global (or a static variable) to do the same without
really changing your rule.
Something like this.
Global Integer ruleFired;
rule try not to loop
when
$a : A($code : code)
$b : B(parentCode == $code)
then
if(ruleFired != 1)
{
addResult($a, $b);
Drools.getWorkingMemory().setGlobal(“ruleFired”,1);
}
end

Subject: [rules-users] Not looping the rule when more then 1 valid match is

Hello group,
Assuming I have the rule:
rule try not to loop
when
$a : A($code : code)
$b : B(parentCode == $code)
then
addResult($a, $b);
end
and the classes:
public class A {
int code;
}
public class B {
int parentCode;
}
I insert into the WM 4 objects :
A(code = 1), A(code = 2);
B(parentCode=1), B(parentCode = 2);
I would like that after calling fireAllRules() only 1 match will be returned. I
have no preference regarding which one, in the current situation 2 matches are
returned.
Anyone could suggest a method to enforce this ?
Thank you,
Maxim.

RE: [rules-users] BRMS in a WAS cluster
Hi Seema, I am attaching the repository.xml we had used. Yes, it could be possible that JackRabbit would need to be configured for clustering.(I guess we missed that one). (You will need to change repository.xml in that case as specified). The main reason we cannot use the BRMS for our current project is that our deadlines do not allow us to wait till the GA of Release 5 (when we can get enterprise support for it) and we cannot use 4.0.7 as it does not have some features important to us(like Security etc). Release 5 of the BRMS is really good and if you can use it, you should go for it.

[rules-users] Changing the default character for delimiter in decision tables
Hi All, I wanted to throw to discussion a feature that might be good in Drools. I am basically trying to model a formula evaluator in a decision table. The idea being that a business user directly defines formulas(without having to use Guided Editors in the BRMS or Eclipse, as business users love Excel more than anything else..;)). The thing I am trying to do is the following: Condition Action T:FormulaFact formulaNameint salary=t.getSalary(); t.setBenefit($1); Formula1 salary * 100 Formula2salary * 1000 Everything runs great as Excel simply substitutes the entered string into the function. The problem I face is when I write something like this: Formula3min(salary,100) The , here is treated as the delimited of a parameter. So the compiled DRL does not set the string correctly. It would make a rule like Rule FormulaTable_123 When T: FormulaFact(formulaName=Formula1) Then int salary=t.getSalary(); t.setBenefit(min(salary); //Since the words after the , become part of $2 which is not defined. End Is there any-way to declaratively change the Decision Table Parser to not use , for delimiting between parameters and use some other character. I could always write the DT using my character, then compile the DT into DRL and replace my character with ,(I am thinking of using Colon), but would it be a good idea to have an Excel or a Property File that can be read by the SpreadSheetCompiler to change the delimited character used by the Parser.

[rules-users] RE: fact base storage?
Hi Jess,
I am facing the same problem right now. While, I do not know of any OOTB ways
to do this, I initially implemented an all rule solution.
In my case, I had a lookup table that based on a age or gender got a rate or
some value.
Using some Excel Trickery, I got the 2 dimensional table into one dimensional
columns of the type:
Age Gender Value
Age and Gender became conditions and Value became the Action.
In your case, you could form a column with a dummy LHS(1=1) and keep all the
columns as Action Columns.
In each Action Column you could build up your Fact.
For Example you could do the following:
Fact{ int a; int b;
}
ConditionActionAction
F: Fact
f.set($1);f.set($1)
Eval(true)Col A Col B
Dummy Value values for avalues for b
If you generate a rule base out of this, it should load your tables straight as
facts.
However, do note, that I did some rather QD benchmarks for this and soon
realized that the rulebase size and memory usage was getting really large.
(Especially the PermGen Size).
You may want to have a look at the memory usage, in case you need to load a
large number of tables. Due, to the above(and other reasons), I just wrote a
custom parser using JXL (The same Excel Library Drools uses for Parsing
Excels). It is really neat and would make a simple solution.
In, case you get another solution do post it to the list.
Cheers,
Vikrant

I'm trying to come up to speed on the drools capabilities. I see that drools
supports loading rules from a decision table in a spreadsheet. I have a set of
conversion tables that I'd like to represent as facts asserted when the rule
base has been loaded, but before processing user requests. I could always
model lookup tables in a database, but I'd rather not have to build the CRUD
interface to manage them. I'd rather represent them so that each row in a
spreadsheet represents a fact (based upon a predefined java bean). Of course,
I could custom implement this functionality. However, I was wondering if
drools supports some OOTB means of loading facts from Excel or other resource?

My suggestion, was that instead of creating your own XML language for storing Rules, you could maybe re-use the existing XML language provided by Drools and use the default rule parsing API's. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of drools newbie Sent: Friday, October 10, 2008 8:17 AM To: rules-users@lists.jboss.org Subject: RE: [rules-users] newbie - dynamic rules in java and db design Hello Vikrant, Sometime ago, you replied to my question as given below.

RE: [rules-users] citation tracking, Jess rule language, export to sourceforge
Hi Mark, This sounds like a really nice BRMS feature, to hold additional meta data. As nice as it is though, it's unlikely the core team will be able to do this at the moment as we have more basic and essential functionality to do first, but we will work with anyone that wants to build and submit this type of feature. Actually, this feature is probably much needed. I have a situation with the BRMS as well, where I was using it to store pricing tables in insurance. Basically, the table was a simple look-up for so and so age and so and so gender the price(or rate) would be X. The issue, I face right now is that I can potentially have quite a few of these tables. I did a small test (Not a proper benchmark, but a quick and dirty test with all dummy records) on how rules would fare with a small three column decision table of 15,000 rows, with 10 concurrent threads. The performance I found satisfactory given I was firing all 15000 rules for each of the threads. On, my PC it gave me 2.5-4 seconds, which was quite decent. However, the memory footprint of the rule-base created scared me. It was over 300 MB. This to me at least does not scale well on a production environment and we would have much more than the simple three column dummy rules I wrote for the test. Another problem, obviously was the time it took to load the rule base(I serialized it to a file) and also the fact that I had to change the Perm-Gen Space settings to get it to work. (Since, every rule becomes a class of its own this would surely be a problem in big rule-bases). Maybe a rules-engine is an overkill for such a simple thing but it is actually part of a much more complex underwriting and pricing algorithm. (Putting everything is rules is really elegant, but alas does not seem possible as the rule-base would become very large!!). The alternative I have thought of is to store the data like the pricing look-up table as a simple excel and then use Rules to extract data from it. The aim being to give the users the flexibility to change the look-up table and then to change rules. Not, sure if this is the best approach still playing around with it. In any case, I am currently still storing the data as an Excel in the BRMS but rather than using it as a rule, would use the REST API to access the Excel and process it. It is kind of hack but I am sure business users would not be able to make out the difference between a business rule asset decision table sheet and an excel sheet with just data in it. As a side note, I am not quite sure, if I can use the templating mechanism to work like this. Instead of creating separate rules for each record, the template could just process data. Hence, it would be great if all we can have is a separate tab under Rules to store Meta-Data and be able to access it from rules as needed. I may do this myself, but since we are taking commercial support from RedHat on Rules, I would need to clarify with them first on what the implications on support are if we change the BRMS.

Specifically, there would be a pulldown menu of article titles previously used as sources, plus a way of indicating the page range within the article. 2) In addition to specifying the source, the widget would allow entering a text description. For example, the description might indicate how the syntax of the original ruleset was changed to accomodate one's own syntax. 3) As a ruleset is maintained, and one finds that rules need to be altered to fit new-found scenarios, one would want to append a new source (article or scenario) to the ones already listed for a rule. The history of sources and descriptions would really help avoid mistakes such as changing a rule to fit a new case but breaking it for older cases. 4) Whenever one wants to write a publication

RE: [rules-users] RE: Deploying the BRMS on Web-Sphere 6.1
Well it is not that serious a problem as I initially thought. As I mentioned the URL(adding the index.jsp) works, so there is an easy work-around available. The main bug seems to be that if a URL is sent to WebSphere which does not have a physical file in it the filter which should kick in and re-direct does not do so. (http://www-01.ibm.com/support/docview.wss?rs=180uid=swg1PK27620) This has nothing to do with the BRMS of course and is a problem for all Web-Apps in this version of Websphere(We are using 6.1.0.0). Adding the index.jsp to the URL seems to work fine for now. I am working on the BRMS to see if there are any other side-effects of this. Maybe, we should update a Wiki or troubleshooting doc on this so that it is known to the community. Digging around IBM Support after my post, I have found quite a few bugs mentioned in version 6.1 regarding how Servlet Filters work and of some on JSF(Especially JBOSS Seam) problems with the particular version. (http://www-01.ibm.com/support/docview.wss?uid=swg1PK47367) IBM has however provided patches for all of them and I am going to give another shot at seeing the behavior after upgrading to a higher release. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Neale Sent: Tuesday, September 23, 2008 5:25 AM To: Rules Users List Subject: Re: [rules-users] RE: Deploying the BRMS on Web-Sphere 6.1 Hi Vikrant. well the drools-guvnor/ doesn't use a filter so much as it is default web.xml behaviour - you can specify a welcome page, which it goes to when the root path is supplied. If Websphere 6.1 can't even do that - I would say something is seriously wrong (may be a bad install?) - you could try it with a really simple war that just has 1 jsp and a web.xml and see if it happens with it? although I think: As for servlet filters - as we use Seam, it uses servlet filters to manage lifecycles, so yes, that could be it (if its not the above). It isn't possible to replace the filters, as they do a very different job from servlets (although the difference is subtle). What would be better would be to work out what the problem is with websphere and filters I think.

[rules-users] Drools BRMS Secrity Features
Hi All, I have a question on using the BRMS which I am unable to find any answers on the internet. Does the JBOSS Rules BRMS have any security features in terms of Role Based Access. For example, is there a way out of the box to specify that user-A can access only these rules (or categories or packages ) and User-B can access this bit only. It need not be too sophisticated. If it is not available at a Rules Level , can it be implemented at a JSP level. That is put in Sever specific URL Filters to not allow access to certain pages(if a page can correspond to a rule)? Any, help in this regard will be a tremendous help for me to make some design decisions regarding the BRMS. Cheers, Vikrant MASTEK LTD.

RE: [rules-users] Drools ruturn multiple results based on child objects data length
My feeling after reading this post is that you need to execute a rule, if some
child object exists.
I suggest using the Exists Feature in Drools for doing something like that.
It would be the same thing if you are writing SQL. If you join a Master Table
with child tables you will get as many records as there are child records for
each master record.
However, if you only want one master record if there are child record, you
would need to use the exists statement.
Example:
rule Multiple results set
when
order: Order
exists ( Invoice from order.invoices)
then
System.out.println(Rule Example (Multiple results set)+order.getId());
end;
Cheers,
Vikrant

Hi,
In one-to-many relationship object type, Drools generate multiple results based

belongs to parent object. I wanted the RHS part should be executed only if
conditions imposed
on child object satisfies.
I have two facts with 1-* relationship defined in object mapping.
class Invoice{}
class Order{

I wanted RHS should be executed with only one result irrespective of child
records length.
rule Multiple results set

Result:
Rule Example (Multiple results set)1000

RE: [rules-users] Drools ruturn multiple results based on child objects data length
Hi Mohamed,
The logical 'OR' operator internally will create two different rules and both
can fire, hence you are getting two different firings.
What you need to use is the following operator , '||'. This should treat it as
one rule and fire if either of the two conditions are true.
Example:
rule test
when
order: Order
(
exists ( condition-1 with child objects || condition-2 with child objects)
)
then
SOP(order id +order.getId());
result :

Thanks Vikrant.
I have one more qurey on 'OR' logical operator for the following scenario:
I want the the boolen result from parent object which satisfies two different
condition sets with child objects. I made the rule which is generated duplicated
results if both conditions are satisfied.
rule test
when
order: Order
(
exists ( condition-1 with child objects)
or
exists (condition-2 with child objects)
)
then
SOP(order id +order.getId());
result :
order id 1000
order id 1000
return the results in twice if both the conditions (cond-1 cond-2) are
satisfied. It just combine
both results and behaves like 'union all' instead of 'union' function.
Can you help on this?

I am a bit of a newbie myself, but I assume the following would work: When $p: ParentFactObject() $c: childFactObject(TestMe==false) from $p.ChildFactObjectList Then //do something End Another way is to simply assert the ChildFactObjectList as separate facts into the working memory and then pattern match just them.
