April 2007 - rules-dev - Jboss List Archives

by Bynum, Joe

I'm doing some simple evaluation of jrules and I ran into a problem. Here's the rule I'm having problems with: rule "751845 - Check Stages" when order : Order( stages excludes 921 ) then System.out.println( "This order contains " + order.getStages() ); end OUTPUT: This order contains [804, 921] I'm actually trying to do the opposite using 'stages contains 921'. stages is defined as follows in the Order object. private ArrayList<Integer> stages; I'm using the 3.0.6 binaries on W2K w/Eclipse. Any ideas what I'm doing wrong here?

allowing self joining combinations

by Michael Neale

I know that we by default remove self joins, ie: when Foo() Foo() will not match for the same instance of Foo - is it possible to turn that off? I know we talked about it at one point, not sure what the latest position is (someone was asking me and I can't recall what our final position is). FYI Jess and Jrules both self join by default.

ClassFieldInspector and Groovy Classes

by Terry Laurenzo

The attached diff (against 3.0.5 sources) adds a condition to the ClassFieldInspector to not analyze methods named <clinit>. For some reason, the Groovy compiler is outputing classes that were causing this check to choke and throw an IllegalArgumentException because of a <clinit> method with ACC_PUBLIC access code. Applying this patch allows Drools to operate correctly with compiled Groovy Fact classes. This seems like a pretty innocuous change that someone should apply to SVN. Unfortunately, it is rather difficult to create a test case for it. Terry Laurenzo

Persistent store and web administration

by Schwenker, Stephen

Hello, We have been using jboss rules for 6 months now and find it to be a good tool overall. On the other hand we have noticed a few down sides. Currently our rule engine runs on a jboss server and is deployed in a sar. Every time we want to change the rules, we have to re-package and re-deploy the app. We want to advance our solution by providing a web application to administer the rules. The first step of this will be to create a form of persistent store for the rules. My first thought is to put it into a database because we can then manage it easily with a web admin. Has anyone done some work on this or can give me some ideas on how I should start working on this? I'm willing to contribute some of my code to the project if anyone is interested. Thank you, Steve.

What is the real benifit of 'From' - DB performance Vs Rete

by Arjun Dhar

Hi, I'm aware that you are working on 'From', to pull external data and use it in the Rule conditions for comparison with that external data. Three Questions: Q1. I could define my own business object that fetches in the data? Cant I? What additional benifit does 'From' give me? Q2. I use Decision Tables extensively; how do I use 'From' in a decision table? is it like a Keyword,.. but I cant imagine how it would be used? Could you please give an example. Q3. When executing PL/SQL logic, the data is at the database itself and so is the logic. 3.1. If we decide to abstract the logic to rules and fetch data from the database, in theory wouldnt pure PL/SQL be faster inspite of Rete running the logic? 3.2. Since most mainstream applications use external data, when we talk about SPEED how significant can the rule engine be? If my conditions depend on external data, does the speed of the rule engine really count? Unless the rule engine is sitting inside the database I have my doubts. ... The above are pratical issues that am sure everyone would ask. Thanks, Arjun

two great bugs

by Mark Proctor

Found two great bugs this weekend: http://jira.jboss.com/jira/browse/JBRULES-778 (fixed) when $p : Person( $cheese : cheese ) then modify( $cheese ) end The above would actually use the $p fact handle for the modify, causing the handle to reference $cheese instead of $p. This is now fixed, field bindings now have their fact hand cleared, so on modify when the fact handle is null it retrieves it from the working memory. http://jira.jboss.com/jira/browse/JBRULES-780 (in the process of fixing) no-loop is currently trapped with: // if the current Rule is no-loop and the origin rule is the same then return if ( this.rule.getNoLoop() && this.rule.equals( context.getRuleOrigin() ) ) { return; } That means we have a tuple that reached the terminal node, but is not added to the memory or an activation created and attached. Thus on a modify or a retract the Tuple reaches the RuleTerminalNode and causes a NullPointer.
