Re: [rules-users] Creating a Query in Guvnor

You wouldn't be able to execute a query after the return of execute() from a stateless knowledge session. Consider writing a low-salience rule that fires for the conditions you'd use in the query and add the matching facts to a global List, or insert a single fact prepared to collect these facts i

Re: [rules-users] Creating a Query in Guvnor

I tried this with no success. Any thought on how to resolve this? I have a package defined in Guvnor and referenced in my change set. I can set it up and fire all rules but I need a way to get the results out of my stateless knowledge session. Any thoughts? David David R Robison Open Roads Cons

Re: [rules-users] Creating a Query in Guvnor

There isn't an explicit editor for this - there's a JIRA for it, but I forget the number. You might be able to work around it by either modifying the drools.package asset or adding a query definition in the advanced view of the package imports or global settings. All are added to the package DRL a

[rules-users] Drools Planner: what if possible values of a PlanningVariable are dependent of another one?

Hi All, I have a PlanningEntity that has several planning variables, say A and B. Now, if A is O then B can be X or Y and when A is P then B can be Y or Z. I see two routes: * create a solution property that generates X, Y and Z as alternatives for B and rely on the score rules to dismiss

Re: [rules-users] Is Drools suitable for preprocessing my Resource Allocation Problem

Thanks very much for this detailled anbwser. this helps me much. I am currently playing with Drools, and trying to build rules in Java from my own Rule objects, with the help of the lang.api. Here are some comments in the flow of your anwsers > > > The optimizer takes as input (among others) a l

Re: [rules-users] Multi-threading inefficiency caused by static class synchronization?

Thank you for the advice. That's a good solution if we choose to deploy the rule engines as standalone services. We are also evaluating deploy the rule engine as a embedded component in legacy applications. In this case they have to be in the same JVM. -Ping -- View this message in context: ht

Re: [rules-users] Multi-threading inefficiency caused by static class synchronization?

Thank you. You are right the locks are guarding the session creation. I will try stateful session with fact retracting. I was using stateless session because the rules I'm going to deploy are all simple rules without much inference. So another question is: to make the multi-threading efficient, I n
