[rules-users] duplicate class in drools
Hello guys, thanks in advance for your attention... I found 3 DebugWorkingMemoryEventListener (ther are lot like this but this is one among them) class in 3 various drools jars *drools-core-6.0.1, knowledge-api-6.0.1 and kie-api-6.0.1 * jars, which one to be use? two from event.rule package and one from core.event package?

Re: [rules-users] Guvnor-5.5
*We're asked how to run Guvnor on WebSphere quite often... * Nothing wrong with the drools expert, the problem is guvnor this is because you are frequently changing the guvnor implementation and architecture, from 5.0 to 5.3 guvnor used components.xml (seam config) for repository and security configurations. Now 5.4 and 5.5 using beans.xml (spring injection). Even though guvnor is used in development environment, very high profile companies and projects this is big problem for upgrading also developers complaints is very important to avoid guvnor as a rule authoring tool or repository.

[rules-users] CommandFactory.newSetGlobal and scope
Hi everyone, I'm reading through Michael Bali's Drools JBoss Rules book as well as the reference guide, and I've got a question of scope about StatefulKnowledgeSessions. I understand that if I call setGlobal on a stateful session, this global value will be shared for all simultaneous calls to executeRules across all threads. I'm looking into CommandFactory, which has a newSetGlobal method. From what I gather, a global set via CommandFactory.newSetGlobal and then executed with a call to execute(CommandFactory.newBatchExecution(cmds)) would be scoped solely to that execution, regardless of it is a StatefulKnowledgeSession and there are other parallel command executions against the same session. Can anyone confirm if that is accurate? Thanks in advance, -- Ricardo J.

[rules-users] Drools Fusion Performance and RETE algorithm
Hi all Looking at Drools JBoss Rules 5 0 Developer's guide it addresses the Fusion component at page 134, stating: This problem cannot be solved by the standard Drools rule engine. The volume of events is huge and it happens asynchronously. If we simply inserted them into the knowledge session, we would soon run out of memory. While the Rete algorithm behind Drools doesn't have any theoretical limitation on number of objects in the session, we could use the processing power more wisely. Drools Fusion is the right candidate for this kind of task. Ok, but my question is if this is enough, because I would guess that Fusion could be used to derived a more complex/rich event from the stream of events, and afterwards that complex event would be inserted in Working Memory (but not the flow of events that have generated the more complex event), thus reducing RETE algorithm processing. But since in our case every event will most certainly fire a rule, I am not sure about Fusion's usage. This is because our project is more a kind of Event-Trigger-Rule/Action system, meaning we have a high volume of incoming events (say more than 5000/minute), but each of the events will have to trigger a rule (and usually a rule is more or less a complex action, invoking DB operations and data structures manipulation). So, by using Fusion entry-points, would that be different than just sending the events as normal facts to Working Memory, or by dividing this in entry-points( or so called streams) we would have benefits in the RETE processing (I am assuming Fusion also uses RETE someway)? Best regards Orlando.

Hi! I faced the same problem once. It was caused by a problem in my code (constraints, actions, etc.). I'm trying it, but I can't reproduce it now. The problem may be solved in lasts versions. Starting a ruleflow process works? Any log? Anything on the problem view? I can remember solving the problem reading those logs in order to find the erroneous code and editing the XML behind the .rf. 2009/3/11 Femke De Backere femm...@gmail.com Hi! As I was creating a new ruleflow, to fit as a subprocess in another ruleflow, I encountered the following problem: My ruleflow is build, and I checked the correctness with the Check the ruleflow model button. When I close Eclipse and reopen my project again, my whole ruleflow (except for the start node) is gone, the xml behind the .rf still exists, but the view is gone. Has anyone any clue what happened?

Re: [rules-users] Re: rules-users Digest, Vol 28, Issue 19
Thanks for the explanation! I've found the CR1 downloads, I've just tried it, and it works just as I needed :). Just one comment. In my first attempts I missed your comment about using a variable with the specific name processInstance... I'm slower than I thought... But, just as a suggestion, it may be better to have a clearer way to use this special matching. Maybe using a fact property or a keyword... ? Well, I don't know anything about the ruleflow project and its complexity so take my suggestion as it is :). Well, thanks again for the help and congratulations for your impressive work! Ricardo. 2009/3/9 Kris Verlaenen kris.verlae...@cs.kuleuven.be Ricardo, This method has recently been added into WorkflowProcessInstance, it is on trunk and will be in CR1.

I tried to use your solution Kris, but I've found that 5.0.0 M5 WorkflowProcessInstance does not seems to provide getVariable method. I've found that method into WorkflowProcessInstanceImpl searching in svn trunk. I must work with that class or I missed something? Thanks again!

If you want to use rule constraints anyway (because your constraints can become rather complex), there are a few options: - You cannot use globals to pass information used in your constraints, because globals are considered immutable with respect to rule conditions - You can put your data you want to access in your working memory. Rule constraints can then access this info just like any normal rule. - You access the variable value using the special processInstance rule constraint (I just added a new section in the documentation to explain): Rule constraints do not have direct access to variables defined inside the process. It is however possible to refer to the current process instance inside a rule constraint, by adding the process instance to the working memory and matching to the process instance inside your rule constraint. We have added special logic to make sure that a variable processInstance of type WorkflowProcessInstance will only match to the current process instance and not to other process instances in the working memory. Note that you are however responsible yourself to insert (and possibly update) the process instance into the session (for example using Java code or an (on-entry or on-exit or explicit) action in your process). The following exampleof a rule constraint will search for a person with the same name as the value stored in the variable name of the process: processInstance: WorkflowProcessInstance() Person( name == ( processInstance.getVariable(name) ) ) # add more constraints here ...

I'm testing how to share a StatefulKnowledgeSession between N rule flow instances.
