Hello, I've been trying out the Spring integration package in Drools 5.1.1 and it works really well, but I have run into one issue I can't figure out.
I've defined 2 knowledge sessions from the same knowledge base in the app context - one stateless, one stateful but otherwise identical. They both refer to a collaborator defined as a bean in the app context which is to be used as a global in my rules. This is just an excerpt of my full Spring context, the kbase definition itself is not an issue. <bean id="applicantDao" class="com.acme.app.dao.impl.ApplicantDaoImpl" /> <drools:ksession id="statelessKSession" type="stateless" name="statelessKSession" kbase="kbase"> <drools:script> <drools:set-global identifier="applicantDao" ref="applicantDao" /> </drools:script> </drools:ksession> <drools:ksession id="statefulKSession" type="stateful" name="statefulKSession" kbase="kbase"> <drools:script> <drools:set-global identifier="applicantDao" ref="applicantDao" /> </drools:script> </drools:ksession> The issue is that this configuration works for the stateful but not the stateless session, in the sense that the stateful session appears to have a valid reference to the applicantDao object in the Globals object but the stateless session doesn't. @Test public void testStatelessGlobal() { Globals globals = statelessKSession.getGlobals(); Object global = globals.get("applicantDao"); Assert.assertNotNull(global); } @Test public void testStatefulGlobal() { Globals globals = statefulKSession.getGlobals(); Object global = globals.get("applicantDao"); Assert.assertNotNull(global); } The first test fails (the global variable is null) but the second passes. No errors are thrown by Drools during the setup of the Spring container. What am I doing wrong? Should I be able to define globals in this way for stateless sessions? The XSD seems to indicate this is a valid configuration, but it just doesn't work. Is anyone else working with the Spring integration that can point out my error here? Many thanks, Patrick
