[rules-users] org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[

Hello, I am new to Drools. On starting to execute a simple program, eclipse gives the following stacktrace as error. I even included the org.eclipse.jdt that comes with eclipse, but it is still giving me error. Anybody please suggest the problem. I am using Drools 5.0 and its dependencies and Eclip

Re: [rules-users] Stateful vs. Stateless Session Performance

Thanks Wolfgang- I did not realize the stateless session was just a wrapper around the stateful session. I think the stateful with manual cleanup after each fireAllRules invocation is the way to go here. As a follow up question, do you think Drools and Rules Engines in general are the way to go f

[rules-users] Query in stateless knowledge session returns no results

Hi all, I'm new to Drools, so please excuse me if I'm asking about the obvious--it's certainly not obvious to me. The problem is this: I use a stateless knowledge session where a list of facts is inserted. The rules that fire create new facts, and after all the rules have fired, I'd like to obt

I am stuck in getting knowledgebase from web application context, I am able to get the knowledgebase and execute rules from that base if it is desktop application. Guide me in this regard, how to get the knowledgebase from web application using knowledgeAgent approach. -- View this message in con

Ah, other engines don't do nested accessors because they're wimps.  WIMPS! :) --- On Fri, 7/29/11, Mark Proctor wrote: From: Mark Proctor Subject: Re: [rules-users] Condition syntax to access Map To: rules-users@lists.jboss.org Date: Friday, July 29, 2011, 8:52 AM On 29/07/

Re: [rules-users] How to add application data via StatefulKnowledgeSession

If the "global" is both modified by rules and investigated by rules: then it's not a global but a singleton fact. You can use a global in a condition, but only if the data obtained from the global is constant over time. I think that your "container" ought to be a fact. -W 2011/7/29 Matthew Erl

Re: [rules-users] How to add application data via StatefulKnowledgeSession

I'm using Drool 5.  I reviewed globals and it looks like it might be appropriate for my situation.  I find plenty of documentation on how to use a global in a consequence, but none on how to use a global in a condition.  Do you know if it's possible to use a global in a condition?  My situation

[rules-users] error resolving class name on imported class when loading package

I am getting an error when the knowledge agent loads a pkg. The rules source file contains an import for a class: com.abclegal.domain.task.FileDocumentsWithCourtTask and the RHS of a rule makes a cast using the class name without fully qualifying it: ((FileDocumentsWithCourtTask)$step.ge

Re: [rules-users] Flow isn't behaving as I'd expect

I've found the answer to my problem - it's behaving as designed, but the design is less than intuitive. Apparently others agree. Here's a thread involving Michal Bali and Mark Proctor which discusses the issue: executing-ruleflow-with-AgendaFilter-td60084.html executing-ruleflow-with-AgendaFilte

Are you aware of the "Expert" manual's Chapter "Authoring", where Section x.2, "Templates" discusses these and, in Subsection x.2.2, "Expanding a Template" shows how to use Collections of Pojos and Maps as parameter provides for template expansions? -W 2011/7/29 David Godfrey > Can someone point

Can someone point me in the direction of documentation or examples for using Rule Templates together with data held in a database (or source other than XLS / CSV which seems to be what all the examples show)? Many thanks, David ___ rules-users mailing l

Re: [rules-users] Stateful vs. Stateless Session Performance

The comparison might not be done with the required fairness. Consider that the stateless session's execute method implies a dispose() call, which you appear to be skipping in the stateful test code. If your rules do not insert secondary facts and if you are able to clean up properly after processi

Re: [rules-users] How to add application data via StatefulKnowledgeSession

Which version of drools are you using? The document you pointed out seems a little bit old. Since Drools 5, you can use globals to use application's data in your DRLs. If you are using Drools 5 or higher, I suggest you to read the documentation about globals. Best Regards, XXX
