Guvnor test scenarios for rules that use globals
by Lisa Horton
In Guvnor 5.1 I have several rules that invoke services defined as globals. Rules that invoke methods on these globals run OK when deployed, but a test scenario that triggers such a rule gets an exception.
For example, with a global named "logger" a rule that has in its THEN clause:
logger.debug("customer was added to session");
Test Scenario that triggers this rule gets the error:
[Error: unable to access property (null parent): debug]
Thanks for your help.

Guvnor 5.2.0 (Final) under Geronimo 2.1.4
by john＠oa
Guvnor 5.2.0 (Final)
Hello
I need to get Guvnor 5.2.0 (Final) up and running under Geronimo 2.1.4
(Tomcat6 variant).
Have started looking at this and have already found that there are class
loading/conflict issues as the container utilises xstream 1.2.2 and the
Guvnor requires 1.3.1.
There are probably a whole host of other issues. Has anyone used the Guvnor
under Geronimo? Any tips on getting this working much appreciated.
Cheers
John

Working with Declared Types
by హరీష్ చౌదరి కూకట్ల
Hello EveryOne,
We are using declared types in our technical rules. But, in the then part of
the rule we want to insert these declared objects to a global list so that I
can get the output. So, is there anyway to insert these declared types into
the list.
Thanks,

Memory leak in 5.2/5.3
by Swindells, Thomas
I'm in the middle of trying to upgrade our application to Drools 5.2 from 5.1 however I keep facing out of memory issues (I've also tried on the current 5.3 beta).
I've simplified my code into the following test case which on my machine after about 600 or so iterations gives an Out of memory exception:
@Test
public void testCase() throws InterruptedException
{
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
for(int i = 0; i < 1000; i++) {
System.out.println("Run " + i);
StatefulKnowledgeSession session = kbase.newStatefulKnowledgeSession();
for(int j = 0; j < 100; j++) {
session.insert(new byte[10240]);
}
session.dispose();
session = null;
System.gc();
}
}
Am I missing anything here - I'm calling session.dispose() which is all I believe is necessary when finishing the session, however using a profiler shows that all the StatefulKnowledgeSessionImpl and ReteooStatefulSessions are still present and therefore keeping hold of all the byte arrays and memory.
Using a profiler it shows that the GC roots of the StatefulKnowledgeSessionImpl are
kruntime of org.jbpm.process.instance.ProcessRuntimeImpl
kruntime of org.jbpm.process.instance.event.DefaultSignalManager
kruntime of org.jbpm.process.instance.timer.TimerManager
kruntime of org.drools.reteoo.ReteooStatefulSession
Similarly for the ReteooStatefulSession:
session of org.drools.impl.StatefulKnowledgeSessionImpl
session of org.drools.impl.StatefulKnowledgeSessionImpl
workingMemory of org.jbpm.process.instance.ProcessRuntimeImpl
workingMemory of org.jbpm.process.instance.ProcessRuntimeImpl
workingMemory of org.jbpm.process.instance.ProcessRuntimeImpl
Is this a known issue? Am I missing anything in my code above.
I guess the alternative is to reuse my sessions - what is the most efficient way to remove all the facts from the working memory and get it back into a pristine state?
Thanks,
Thomas
