I am using the Drools 5.4 integration server in a stateless session. I have it running fine with the example. Now, I want to use custom Quartz calendars in my rules. The only way I could come up with to do this in Spring (a la integration server) was to create a bean that takes a ksession constructer then creates the calendars and adds them to that ksession. I see that the bean is created with a knowledge session and all seems ok, but none of my calendar-based rules ever fire regardless of how the calendars are configured. (I test the calendars in my bean (with a call to isTimeIncluded()) and they seem to be in working order. Also weird is that bean's constructor gets called twice and with two different knowledge sessions. Once when I start the application, and then again when I send to the rules service. 1) What is the right was to add custom calendars to a knowledge session (via Spring)? 2) Any idea why my bean is getting called twice with different knowledge sessions? Thanks for any insight. -J ---in knowledge-service.xml <drools:ksession id="ksession1" type="stateful" kbase="kbase1" note="node1"/> <bean id="myCalendar" class="org.test.MyQuartzCalendarLoader"> <constructor-arg ref="ksession1"/> </bean> --- MyQuartzCalendarLoader.java public class MyQuartzCalendarLoader { private static StatefulKnowledgeSession thisSession=null; public MyQuartzCalendarLoader (StatefulKnowledgeSession thisKs) { //gets called twice? thisSession=thisKs; print thisSession.tostring() -- looks ok WeeklyCalendar calendar = new WeeklyCalendar(); org.drools.time.Calendar onlyWeekDays = QuartzHelper.quartzCalendarAdapter(calendar); calendar.setDayExcluded(Calendar.WEDNESDAY,false) -- I toggle just to test print onlyWeekDays.isTimeIncluded(now.getTime()); --- also works as expected Calendars cals = thisSession.getCalendars().set("ONLYWEEKDAYS",onlyWeekDays); } } --- test.drl rule "weekdays" dialect "mvel" <-- This rule never fires unless i remove calendars. calendars "ONLYWEEKDAYS" when $m:Message() then $m.text = "FIRED" end -- View this message in context: http://drools.46999.n3.nabble.com/Add-calendars-to-knowledge-session-from...
