Re: [rules-users] RuntimeDroolsException as Solver concludes execution
Looks like an NPE in your rule. Maybe maintenanceSlot or something is null. You should raise an issue with drools-core (drools expert) that it should give a better runtime error to show on which line it NPE'ed. With kind regards, Geoffrey De Smet dweppenaar schreef: Hi. I am experiencing the following exception: org.drools.RuntimeDroolsException: Exception executing ReturnValue constraint org.drools.rule.returnvaluerestrict...@a5f6c234 : java.lang.NullPointerException. The rule that is causing the exception to occur is the following: rule spreadOvertime when $violatingTask : MaintenanceTask(eval(maintenanceSlot.getAvailability() == 1), motor != null, maintenanceTechnician != null, $overtimeTaskID : id); ArrayList( $numberOfViolations : size ) from collect( MaintenanceTask( id == ($overtimeTaskID + 1) || id == ($overtimeTaskID + 2) || id == ($overtimeTaskID - 1) || id == ($overtimeTaskID - 2), eval(maintenanceSlot.getAvailability() = 1) ) ); then insertLogical(new IntConstraintOccurrence(spreadOvertime, ConstraintType.NEGATIVE_SOFT, $numberOfViolations, $violatingTask, $numberOfViolations)); //System.out.println(Rule Fired: spreadOvertime ( number of violations: + $numberOfViolations + for task + $violatingTask + )); end The purpose of the rule is to spread the closer to normal maintenance shifts. Just to clarrify what the objects are: MaintenanceTask: Consists of a MaintenanceSlot, MaintenanceTechnician and Motor MaintenanceSlot: Day, Timeslot, Availability and Index The 'availability' of a MaintenanceSlot specifies whether it is considered Overtime, ProductionTime or Normal Maintenance This exception is thrown at the end of solving as the solver (I presume) is supposed to return the best solution. The score is calculating and updating but at the end of the specified step count, this exception occurs. If I comment this rule out, no exception. Any help would be appreciated!

Hello Edson, Frankly, I wouldn't spend a lot of time on this. The alternate approach is to inject the working memory into the Seam component as described in the docs.

I'm guessing the Seam guys tested this before releasing, so I'm assuming (as Edson pointed out) a JVM issue with Mac OS X Leopard?

Re: [rules-users] RuntimeDroolsException: Unable to load -- Solved
Solved. Actually, Mark Proctor solved this several days ago when he asked if Seam came with its own Drools jars. It does. If you use the non-Seam bundled drools jars, you will get this exception. Sorry for wasting anyone's time on this, but I'm curiousany ideas what is different between the standard Drools distribution and what comes with Seam?

Re: [rules-users] RuntimeDroolsException
This exception is thrown when it cannot find (one of) the necessary libraries for loading the Java Dialect. In this case probably the eclipse jdt compiler. Make sure all the necessary dependencies are in your classpath. If you are using a Drools project, the Drools classpath container should automatically do that for you. However, note that the eclipse plugin currently only works with eclipse 3.2.x, it will be upgraded to 3.3 for the next major release. If I remember correctly, I believe this exception is thrown if you try to use the plugin in eclipse 3.3.
