Using external classes in BPMN (serviceTask?)

by sam.squire＠paretopartners.com

Hello, I can run Java from within a scriptTask but do not seem to be able to use external classes properly. How might I call methods on a class using a serviceTask? A previous post[1] referred to creating an interface of the class and then referring to that interface. Is that interface the equivalent of an import in the native drools XML format? [1] http://www.mail-archive.com/rules-users@lists.jboss.org/msg15014.html Has anybody been able to get this to work? Can anyone point me in the right direction? Thanks!

error importing java built in api's inside functions

by Kripa Nathwani

Hi, Inside a function I am trying to import java api i.e. java.math.* so that I can use in built math function to perform certain calculations but it does not recognize and validate it. I also tried to import the rt jar file(through "new file" option in drools 5.1 ) but the package does not get built and gives import error. It seems it is not able to recognize the jar. Is there any way by which I can use the java api or start importing the api jars into package(I don't want to use it as fact. Hence I am not using "upload pojo model jar" option).

Specifying time in date-effective

by devyani.sapre＠wipro.com

Hi All I am using 4.0. I have a requirement to execute a rule only during a specified time of a given day While going through the documentation I found that I could use the date-effective attribute to specify the date and time 6.5.1.8. date-effective default value : N/A type : String, which contains a Date/Time definition A rule can only activate if the current date and time is after date-effective attribute. But while trying out the same, the engine recognizes only the day and not the time. How do I specify the time? So far I have been using the std format HH:MM:SS , tried both 12-hr and 24 -hr format but no luck. Please help. Also, I would like to know how can I make a rule run on a specified time everyday. With date-effective specifying a date would be mandatory? Is thr a way or I need to put that in the rule condition part.

Drools Flow: Activities and Sequence Flows

by Simon Peter

Hi, Although the BPMN2 specification hasn't actually been ratified as yet, Drools 5.1.x does appear to be backing BPMN2 (obviously a good decision!). However, according to the spec, Drools isn't doing BPMN proper - and regardless of whether the spec has been ratified or not, it could be closer than it is. There are a couple of examples I've come across, but the most obvious one is the treatment of multiple sequence flows entering and leaving activities. Where Drools requires a Gateway for this, the spec does allow it. To quote from the spec: "But there are special considerations relative to Sequence Flows when applied to Activities. An Activity that is the target of multiple Sequence Flows participates in 'uncontrolled flow.'" It goes on to describe the expected behaviour; the sequence flow should behave as an exclusive gateway. See page 441 of the spec available @ http://www.omg.org/cgi-bin/doc?dtc/10-06-04.pdf (it's a 7.5 meg download) I can raise a bug if that is appropriate. - Simon

Chained Rules

by djb

Hi all, I know there are some basic ways to chain rules together, by setting flags in consequences that are checked in the conditions of other rules... but in a large system based on rule templates, where thousands of rules are generated, it is not feasible to chain rules in this manner, especially when they are chained in a somewhat arbitrary fashion (eg. True if Rule 130 AND Rule 200 AND Rule 480 fire) has anyone had this situation before? would I need to execute this as a post-processing step? or, is there any design pattern that will allow rules to be chained, preferably in a manageable way? regards, Daniel -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Chained-Rules-tp77549...

Change drools process variables

by jawa

Hi, I am writing a drools flow which is backed up by JPA. It get stored into db and then reloaded etc. I've some user task nodes on which flow stops and gets stored in db. Then i reload it from db and resume flow etc. When i start my flow I supply it with flow parameter map. It starts with those flow variables. Now when it reaches a user task it stops there and get stored in db and wait for that node to complete. Then for a certain type of request I reload my session and complete the work item and flow resumes from where it stopped last time. What i wanted to know is can I modify the object i inserted into flow while starting it first time? Is it possible at all? Thanks -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Change-drools-process... Sent from the Drools - User mailing list archive at Nabble.com.

Difference between documentation and eclipse

by Ashish.zokarkar

Hello, I am referring documentation from http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-flow/html... link and downloaded the eclipse plug-in from download page. But in eclipse screen, I am unable to find some nodes like (state or foreach node). I attached the screen shot of eclipse. Please refer that and let me know, if I have to do something extra to get them. http://drools-java-rules-engine.46999.n3.nabble.com/file/n1594927/nodes.png Ashish -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Difference-between-do...

Loop back flow

by Ashish.zokarkar

Hello, I am trying to create a sample loop back flow using drool. What I want is, according to condition, flow should either complete or go to 1 state (s1). But I am not able to loop back using diverge control. Using which node, we can do the loop back?? I attached the screen shot with it. Please refer it and let me know your comments on this. http://drools-java-rules-engine.46999.n3.nabble.com/file/n1594971/flow.png Ashish Zokarkar -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Loop-back-flow-tp1594...
