[rules-users] rule compilation problems
Hi all, I am new to JBoss. I just finished making my first program with Rules and it works fine, but when I try to integrate all that into my web application (using Jetty), I get the following error: [java] java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems() [Lorg/eclipse/jdt/core/compiler/IProblem; [java] at org.apache.jasper.compiler.JDTCompiler$2.acceptResult(JDTCompiler.java:341) [java] at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:417) ... I tried to fix the problem with: conf = new PackageBuilderConfiguration(); conf.setCompiler(PackageBuilderConfiguration.JANINO); ... PackageBuilder builder = new PackageBuilder(conf); builder.addPackageFromDrl(new StringReader(rule.getText())); ruleBase.addPackage(builder.getPackage()); as in http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesTomcat but it's not working either. Same message. Can you help me? Thanks G. Arias del RIo ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Michael Neale michael.neale at gmail.com writes: Yes, as discussed, you need to add import statements for the types you want the BRMS to be aware of - if you like, create a feature request jira for auto importing. I deliberately didn't do it cause I thought it would cause more confusion, but perhaps I was wrong. Also, the video on the blog: http://markproctor.blogspot.com I made shows this.Michael. - The other question is: How could us contribute (If any interest on this, of course) , with the module? In particular we are looking for internationalization stuff. It is very important for us, and I think might be interesting for others users. Thanks Speaking of internationalization, I have a more specific question. I'd assume that using one Working memory for rules for one country would be advisable. Now, my business object model would be different also hence the Question: Q1) Can we have a base model that is shared across rules firing in multiple WM's and certain extended objects only loaded for certain WMemories??? I'm sorry I have not invested too much time studying the Drools 4 Class Loaders hierarchy so if you could just tell me the answer, I'd appreciate it. Will reasearch it later in detal. Q2) For that it would also imply when loading (DRL -- Package -- Rule Base -- W.M); Rule bases to Working memory we also have to worry about the object model. So, in the diagram for JBoss Rules 4 (http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesRepository) we only see a deployment strategy for the RuleBase and not its corresponsding Object Model; so that gives me a feeling that all object models are shared. Is this true? ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Removing Child Class Objects in dsl file level
My Code has the following Hierarchy. I am facing some problem, while I try to
remove the Child level class object in .dsl file level.
Class1:
public class Class1{
private Class2 class2;
//getter setters for class2
}
Class2:
public class Class2{
Private Class3 class3;
//getter setters for class3
}
Class3:
public class Class3{
Object[] class4;
//getter setters for class4
}
Class4:
public class Class4{
private String variable;
//getter setters for variable
}
I will get only the object of Class1 in dsl level. When I try to remove the
variable in Class4, I am facing some problem. I need to iterate the variable
in Class4 and check weather all the values in the list of variable are same.
workingMemory.assertObject(class1); // in test class
I was not suppose to assert the object of Class2 or Class3 or Class4.
[when]Some English Text = Class1(cl2 : class2) //in .dsl
file
[then]Log {message}=System.out.println({message}); //in .dsl file
I tried the above code. But I can remove only the Class2 from Class1. I
can’t remove the Class3 from Class2 Class4 from Class3 for futher
iteration.
Can some one help me on this issue?
Thanks.

Re: [rules-users] Double
That's what modify does, it retracts the fact and then asserts it. Mark Matthew Shaw wrote: Hi Scott, My understanding is that the rule will only fire twice regardless because there are only two SheetTotal objects in working memory which is stopping the rule from going into infinite recursion. The no-loop attribute is also behaving correctly as it is not letting the engine add it back onto the Agenda. What is interesting however is that in this case the modify is behaving exactly as if I were to retract and then assert the DutyHourTotal object. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Scott Reed Sent: Wednesday, 30 May 2007 11:48 AM To: Rules Users List Subject: Re: [rules-users] Double Matthew Shaw's message received 5/29/2007 9:39 PM: ok point taken. I have modified my rule so that it looks at an object and I modify a property on that object instead as follows: But still the same issue. * * *rule* sum higher rate totals *salience* 970 *no-loop* *true* *when* timesheet : TimesheetTransferObject( ) total : SheetTotalTransferObject($ihrisType : ihrisType - ($ihrisType.equals(ihrisType.getDutyHourTotal())), $payRate : payRate - ($payRate.equals(timesheet.getOfficer().getSubstantiativeRate()) == *false*)) *eval*(total.getValue().doubleValue() 0) higherDutyTotal : DutyHourTotal( ) *then* higherDutyTotal.setNrHours(DateUtils.addElapsedTimes(higherDutyTotal.g etNrHours(), total.getValue().doubleValue())); *modify*(higherDutyTotal); This modify call tells the rule engine to look at this DutyHourTotal object again. The rule should just keep firing. If there were some condition on the DutyHourTotal that eventually was false it would stop but I am surprised you only see it fire twice and not forever. Perhaps there are side effects of setNrHours() that cause one of the other conditions to fail. * end ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users This correspondence is for the named persons only.

[rules-users] Re: JBRMS Query, very imp for me
Hi Mark, You are right I would try to use Hibernate to store data in MySql. But I have a different problem. For creating rule package through JBRMS I have done following stuffs: The project is really great. but i am unable to download the binary package. The steps followed by me is as below: 1. created a category. 2. created a package associated with that category. 3.Loaded a fact model which is a bean class and linked it with the package. 4. created some business rules. 5.imported the bean class in the configure package option and saved the changes. 6. created a new snapshot. 7. Build the package and it shown a success message too. 8. Now tried to download the package but it is giving package not found. Please let me know the solution. The message below is shown after i have created all the necessary stuffs. Building a package will collect all the assets, validate and compile into a deployable package. and the message that Package built successfully. But cant down load the package as it is giving the following menage.

[rules-users] About Decision table
Hi to all, we wrote some rules as follows package com.leave import com.leave.paternity; rule Paternity Approved salience 1000 when paternity : paternity(gender == 'male',status =='married',role =='permanent',tenure = 2,year == 1,applied ==2); then paternity.eligible = 2; paternity.available = 2; System.out.println(leave approved for : + paternity.getname()); System.out.println(Total eligible leaves are : + paternity.getEligible()); end rule Paternity Approved1 salience 800 when paternity : paternity(gender == 'male',status =='married', role =='permanent(Onsite)',tenure = 2 , year ==1, applied ==2,withinmonth = 30); //withinmonth means if applied with in a month after returning from Onsite then paternity.eligible = 2; paternity.available = 2; System.out.println(leave approved for : + paternity.getname()); System.out.println(Total eligible leaves for employee Onsite are : + paternity.getEligible()); end And they are working fine in jboss 4.0 But we need help that in (from the above how can we write decision table for user (non developer that he wants to change the rulse) Pls give us some useful suggestions Regards: Kranthi Dalai ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] DSL to DRL File Conversion - Is it possible ?
Hi Mark , Can you just help me in converting this drl to dsl. ? How do i break lines in DSL involving OR conditions.? [when]- works for AND conditions . Do i really need give some english text (DSL mapping) for each line of the when condition when i use [when]- //Sample drl file. package com.fruit; import com.test.sample.*; rule FruitExample when C: Customer(); Fruit ( name == apple , costinrupees == 10) ; eval ( C.getNumOfCustomers() == 20 ( C.getCityname() == kanput || C.getCityname() == Disput )) then System.out.println(Rule Success); end The above conditions could be wrriten on a single line using eval() . But this looks pretty long. Are there any other options i coudl try for breaking line.? Do we have any workarounds for this.? Mark Proctor wrote: Its not straight forward but you can use the DRLDumper, one a PackageDescr, assuming it parses without errors: DrlParser parser = new DrlParser(); PackageDescr pkg = parser.parse( source, dsl ); final DrlDumper drlDumper = new DrlDumper(); final String drlResult = drlDumper.dump( pkg ); Michael Neale wrote: no in 3.0 version unfortunately. You can tell the parser to print out the DRL - but it will just write it out the System.out (only for debuggin). Look in RuleParser for that option. In trunk - which will be the new version - there is a seperate step which outputs DRL - but I don't think that made it into the M1 release - should be in M2 though.

Re: [rules-users] Or and Collect
Edson Tirelli was heard to exclaim, On 05/29/07 17:13: $badBugs : List() from collect( Bug( (devOwner memberOf $group || supportOwner memberOf $group), severity == hair-on-fire ) And use || and for connecting constraints and and and or for connecting CE's. Ahh, ok. From the examples I'd seen, it was hard to tell, and the docs still show the two as equivalent for connecting CEs (section 3.15). This will allow me to replace an ugly predicate hack with a clunky but workable parenthetical grouping. Of course, if you'd care to implement yet another handy Collections-based constraint, I could make it really clean: We've got contains, and now memberOf (thanks for implementing my suggestion), so how about intersects? CheeseCounter( stinkyCheeses intersects crumblyCheeses ) Then I could write my rule like so: collect( Bug( (owners intersects $group), ... This would save me from having to edit ten or twenty rules when management inevitably decides that another kind of owner has to be included in the rules -- there are actually five owners now (which makes for a very ugly parenthetical). Can I file a jira for intersects, or should I quit being greedy, and enjoy the shiny new memberOf that I am in fact very happy about? :) -- Dirk Bergstrom [EMAIL PROTECTED] _ Juniper Networks Inc., Computer Geek Tel: 408.745.3182 Fax: 408.745.8905 ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
