how to create kbases with useful names for JMX

by cjohns13

How can I create new container / knowledgebases so that the names as shown in JMX are not random UUID() strings?

by Péter Gergely, Horváth

Hi All, I am evaluating Drools 6 for one of our projects but found a strange issue with Eclipse integration; debug functionality does not seem to work at all. Only Rules view displays the rules (which is I believe independent from the debugger) but all of the other views (Agenda, Audit, Global Data, Process Instance, Process Instances, Working Memory) are always empty. I have confirmed that Drools nature is enabled on the project (it is actually the example project generated by the Eclipse … [View More]

@propertyReactive not work when condition are coded in java

by wtang

I have rule1 and rule2 and rule1 is modifying an object whose property is checked in the when part of rule2 and rule2 should fire. The problem is rule2 is not firing. When I took out the @PropertyReactive annotation, then rule2 will fire. After further investigation, I find the cause is because in the when part I am calling java function to do the comparison as suppose to using native operators like "==". Property Reactive seems to be not working when in the WHEN part of the rules we are … [View More]
