Hi All- I'm trying to use Drools in a Spring 4 applications. Trying to inject
a StatelessSession in a Spring bean:
@Service
public class RulesServiceImpl implements RulesService {
@Inject()
private StatelessKieSession kStatelessSession;
...
}
This results in:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type [org.kie.api.runtime.StatelessKieSession] found
for dependency: expected at least 1 bean which qualifies as autowire
candidate for this dependency. Dependency annotations:
{(a)javax.inject.Inject()}
pom.xml is as follows:
<kie.version>6.0.1.Final</kie.version>
<drools.version>6.0.1.Final</drools.version>
<dependency>
<groupId>org.kie</groupId>

<version>${drools.version}</version>

<dependency>

</dependency>
and applicationContext.xml:
<kie:kmodule id="kmodule1">
<kie:kbase name="kbase1" packages="rules">
<kie:ksession name="ksession1" type="stateless" />
</kie:kbase>
</kie:kmodule>
<bean id="kiePostProcessor"
class="org.kie.spring.KModuleBeanFactoryPostProcessor" />
I also tried the other route:
@PostConstruct
public void setUp() {
KieServices kieServices = KieServices.Factory.get();
KieContainer kContainer = kieServices.getKieClasspathContainer();
kStatelessSession = kContainer.newStatelessKieSession("ksession1");
}
This results in NullPointerException:

I do see the following in the console:

try the following....
RulesServiceImpl.java
@Inject
ApplicationContext context;
StatelessKieSession kieSession;
KieBase kiebase;
@PostConstruct
public void postConstruct(){
kieSession = (StatelessKieSession) context.getBean("ksession1");
kieBase = (KieBase) context.getBean("kbase1");
System.out.println("kieBase == "+kieBase );
System.out.println("kieSession == "+kieSession);

The above code works perfectly if it is a batch program.
It doesn't work in a Spring MVC web project.
Is that a known issue?

It’s not a known issue, but that doesn’t mean it isn’t an issue. I guess open a JIRA, and
maybe take a look into yourself, to see if you can figure out the fix.

Hi Alan- I am not able to reproduce the issue anymore. It 'just' is working fine.
No problems at all.
We recently did install a lot of long due ubuntu updates though.
Really sorry for this.

It’s not a known issue, but that doesn’t mean it isn’t an issue. I guess open a JIRA, and
maybe take a look into yourself, to see if you can figure out the fix.

The above code works perfectly if it is a batch program.
It doesn't work in a Spring MVC web project.
Is that a known issue?

Can you provide the entire path of the pom.properties files in your
application?

I debugged the issue.
Hi The problem is that it fails when you have the sessions and modules
defined in a jar.
The path to the pom.properties in the jar file is:
META-INF\maven\com.verisk.sws.csp\cepCSP
Also I have the issue with webpshere. This treats jars as wsjar
There is no condition in the kie-spring integration code to handle wsjar.
So it thinks it is a file system and subsequetly fails.
Thanks,
Alan
