ANT Compile issues
by Bhamidi, Krishna
Hi,
I am using DROOLs 5.0.0 CR1 and use the compiler from Drools-Ant. When I attempt to execute the rules using a rule agent, I get an exception that in part reads
java.lang.NullPointerException
at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1820)
(Full stack follows this e-mail.) However, when I download the pkg file for the same ruleset from Guvnor and use it in the rule agent, it runs fine.
I use the following for building -
<taskdef name="compiler" classname="org.drools.contrib.DroolsCompilerAntTask" classpathref="compiler.classpath" />
<compiler srcdir="../${rulesDirectory}" tofile="../${buildDirectory}/${projectName}_rules.pkg"
classpath="../${buildDirectory}/${projectName}_rules.jar"
binformat="package">
<include name="*.drl" />
<include name="*.brl" />
<include name="*.xml" />
<include name="*.dslr" />
<include name="*.xls" />
</compiler>
What I should do to compile correctly?
Full Stack

Any news on Drools 5.1

I am planning on diving into a Drools based workflow related project pretty
soon and have kind of been waiting for 5.1 to come out (or maybe the next
milestone release). Any news on 5.1 availability? Thanks -Chuck

drools expert: memory issues
by Miguel Machado
hi all,
I'm quite new to the drools rule engine and i've been using it for a project where i need to filter events and execute actions accordingly.
I'm currently running a DRL file and creating a stateful session from it, and then running 2/3 facts every time. Every X seconds I collect the available facts and call fireAllRules() + dispose(), always within the same session. The DRL file has circa 2160 rules declared (an external program is producing them), and i'm using the "no-loop", "lock-on-active", "activation-group" and "agenda-group" options on almost every one.
My main problem is that the software is consuming too much memory when it loads the rules to the knowledge base variable, it reaches +300Mb which is just not affordable in this project. Is there any way i can work around this? I've tried setting some configuration properties but to no avail. What techniques may i try in order to reduce memory load on drools startup? What would be the best approach for dealing with so many rules?
Anything would help, thanks in advance,
_ miguel

Extending the "validation of rules" functionality in Guvnor
by Premkumar Stephen
Hello everyone,
Currently, the validate functionality ensures that rules have proper
syntax.
it is possible to extend this functionality so that business use cases might
also be validated? Is there an API/examples to do that.
For eg, in our domain, an object X can be evaluated for 3 criteria ( a, b,
c )
However, we would need to prevent rules written which combine criteria b and
c
Rules can have the combinations ( a,b,c, ab, ac ). Combinations ( bc and abc
) should not be allowed.
Regards,
Prem

How to do Exception Handling???
by nanic23
I have a ruleflow that handles exceptions when they are raised by a "Fault"
node but I am not being able to accomplish the same if an exception is
thrown by a workItem or an action node instead.
I have a workItem node with a work item handler that throws a
RuntimeException. My exception handler in the composite node is not catching
this exception.
So, question
1) how can I handle runtime exceptions thrown by my workItemHandlers?
2) how can I get a hold of the exception to log the stack trace?
Any ideas or tips are very appreciated.
Nick.

Issue with drools-flow/persistence
by Daniel Ilkovich
I'm stumped. I'm trying to implement persistence with Drools-flow, and I'd
like to grab the value of a property on a workitem / processinstance, but
everytime I try to get the workitem or process instance I end up with the
stack trace below.
I'm walking through the source and from what I can tell, this happens
anytime I try and grab a property that is annotated with @Lob in an entity
class.
My environment is hibernate/mysql/JPA persistence using BTM as a transaction
manager.
These are the relevant lines of code:
ksession =
JPAKnowledgeService.loadStatefulKnowledgeSession(ksession.getId(), m_kbase ,
null, m_environment);
m_pi = ksession.getProcessInstance(m_pi.getId());
What am I doing wrong?

Resuming the Flow: SESSION_ID, PROCESS_INSTANCE_ID, WORKITEM_ID
by tolitius
Hi Flow Crew,
This is about reloading the session and resuming the flow.
Let's say the flow reached one of its wait states, and was persisted.
Two days later an "assigned actor" does his/her duties, and the flow can
be resumed.
At this point, we need to call something, let's call it a
WorkflowService, that would have a resumeFlow( someBusinessId ) method that
will be called.
Here is where the question starts...
I understand there are three pieces in this puzzle: SESSION_ID,
PROCESS_INSTANCE_ID and WORKITEM_ID
I also understand that in order to resume the flow, I need to get a hold
of that certain work item that is ready to be completed, and let the flow
know it is completed.
But at the point, where I should resume the flow, I have no reference to
neither SESSION_ID, PROCESS_INSTANCE_ID or WORKFLOW_ID.
1. How are these three related to each other?
2. How do I find these three associated IDs?
2. Which one(s) do I need to resume the flow?
3. If I (somehow) get the reference to SESSION and PROCESS_INSTANCE
ids, how do I know which work item is ready to be completed?
Thank you,
/Anatoly

Drools Flow: looking for a Fault Node / Handler example
by Nol de Wit
Hi all,
In the documentation and other articles I reed about the Fault Node,
and how it acts as a bit of an End Node in Flow.
I've been searching on the net in general, and the mail-list archive
in particular for an example on how to use this, but without much
success.
In mostly interessted in the 'Exception Handlers' that apperently can
be used for this. What is the format of such handler, and how to
register it...
Thanks,
Nol
