Personally, I never use DRL functions. I create my functions in a java class module, and I import functions into drools. I have noticed that in earlier versions of Drools (I don't know about recent versions), that using drl functions put a larger load on system than using imported external functions. Plus you gain the added benefit of being able to use your IDE's built-in debugger to step through the function logic. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of ipeshev Sent: Wednesday, January 25, 2012 10:17 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] Debug rule functions ? Hello, could some give me some tips for debugging *functions* in .drl ? by now I'm not able to debug *inside the functions* which are called by the rule sequence. I follow the http://docs.jboss.org/tools/3.0.0.GA/en/drools_tools_ref_guide/html_singl... JBoss Drools Tools Reference Guide but what is show there is how to debug a very simple *rule sequence*. I have no problem with that - following the guide everything is ok. BUT There is nothing shown about a more complex case when there are functions (java-like) in the .drl file and the rule calls one or more of these functions. And one function calls another etc. (just like in normal programming) When a put a breakpoint inside functions I cannot debug them. I can only debug the *rule* ("then" section) Any help would be appreciated? Or any official info if this supported at all. versions etc. Best Regards Ivan -- View this message in context: http://drools.46999.n3.nabble.com/Debug-rule-functions-tp3689774p3689774....

Hi, the best option I've seen by now is the one mentioned by Armand Welsh - use imported java class with methods instead of drools functions. btw: by now I group my classes into jars, but I've never tried to use standalone .class files. anyone tried this? anything special (some settings) in order .class to be found? (note: I use local .drl files instead of Guvnor repository to load rules into memory) -- View this message in context: http://drools.46999.n3.nabble.com/Debug-rule-functions-tp3689774p4020602....
