Hello Everybody,
I've used Drools5.1.0 and I have following Config In Spring :
<drools:resource id="profileChangeProcess" type="DRF"
source="classpath:/process/profilechangeprocess.rf"></drools:resource>
<drools:resource id="documentsRule" type="DRL"
source="classpath:/rules/documentsrule.drl" />
<drools:resource id="ChangeSet" type="CHANGE_SET"
source="classpath:/ChangeSet.xml"></drools:resource>
<drools:resource-change-scanner id="scanner" interval="10" />
<drools:kagent id="agent" kbase="knowledgeBase"
new-instance="true">
<drools:resources>
<drools:resource ref="profileChangeProcess"></drools:resource>
<drools:resource ref="documentsRule"></drools:resource>
<drools:resource ref="ChangeSet"></drools:resource>
</drools:resources>
</drools:kagent>
<drools:kbase id="knowledgeBase"></drools:kbase>
now when i run the code i get following exception :
org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'kSession': Error setting property values; nested exception
is org.springframework.beans.NotWritablePropertyException: Invalid property
'knowledgeAgent' of bean class
[org.drools.container.spring.beans.StatefulKnowledgeSessionBeanFactory]:
Bean property 'knowledgeAgent' is not writable or has an invalid setter
method. Does the parameter type of the setter match the return type of the
getter?

Thanks

I'd refer you to one of the other emails:
"Rules Fest is in full swing, http://rulesfest.org/html/home.html. Great attendance
with around 100 people and great food :)
Myself[Mark], Edson and Davide are here. Davide did a great lunch time talk. Kris will be
arriving on Wednesday to help with the BootCamp.
It's been a lot of preparation last week and we'll be very busy this week and
next, so apologies if our responses aren't timely on mailing lists and irc."
My best advice is you may be able to work around it by defining the beans using normal
spring syntax and not using the drools namespace

Could you please create an isolated test case for this? I'm at the rule fest
right now, but i would like to take a look at this later.

Hi Esteban,
I dont think we need separate usecase here. At least in my case i have tried
with the test case provided in the source code 5.1.1.
Please try in this package
Version: 5.1.1
Module Name: drools-container
Test class:
org.drools.container.spring.beans.persistence.JPASingleSessionCommandServiceFactoryTest
The test/resource folder has 3 beans.xml file. choose any one of them and
try configuring with Kagent+Ksession with JPA
Please let me know if you need any other information.
Regards,
K R Kaleraj

I'm asking you for a test because there is already a test in drools that
uses kagent+kbase spring configuration. The test is
org.drools.container.spring.SpringDroolsTest and uses
org/drools/container/spring/kagents-beans.xml configuration file.
Could you check the tests present in that class?
Best,

Thanks for the response.
In fact, I have seen these files earlier. Moreover I am just trying to run
the test provided which is not working. The file you mentioned has kagent
but missing persistence configuration. I doubt this issue comes while you
are trying to configure JPA.
Please configure kagent in beans.xml provided at
org/drools/container/spring/bean/persistence/beans.xml
I want to configure a kagent for the below kbase configured in that file and
should use in ksession mentioned below.
<drools:kbase id="kbProcessWorkItems" node="node1">
.....
<drools:ksession id="jpaSingleSessionCommandService"
type="stateful"
kbase="kbProcessWorkItems">
.....

I'm running 5.2.0.SNAPSHOT here. What I did is to add a new test in
JPASingleSessionCommandServiceFactoryTest:
@Test
public void testAgents() throws Exception {
KnowledgeAgentImpl kagent1 = ( KnowledgeAgentImpl ) ctx.getBean(
"kagent1" );
}
I also have added the agent's definition into beans.xml:
<drools:kagent id="kagent1" kbase="kbProcessWorkItems"
new-instance="true"
/>
The test works. Could you try this same test in 5.1.0? Maybe we are dealing
with an already fixed bug. Again, that is why I'm asking you for an isolated
test case.
Best,

Hello Esteban,
NOTHING CHANGES. Same issue continuous. Please check the exception stack
trace in the post beginning by Kiran. We can not use 5.2 at the snapshot
stage. Please let us know the work around.
excerpt of my bean.xml is below...
