Hello,

I experience a problem autowiring my KieSession object into my Controller field in Spring.

I read the Spring integration configuration part of Drools documentation and edited my Spring

configuration as adviced. However on deploying I receive one and the same well know exception:

"org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.kie.api.runtime.KieSession] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.kie.api.cdi.KSession(name=, value=ksession-rules)}"

My application's web.xml defines my spring configuration entries as follows:

<servlet-name>mvc-dispatcher</servlet-name>

......

</servlet>

<servlet-mapping>

<servlet-name>mvc-dispatcher</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

/WEB-INF/beans.xml,

/WEB-INF/security.xml,

/WEB-INF/entityManager.xml

</param-value>

</context-param>

As guided by Drools documentation I entered the following Drools configuration in my spring configuration (I try to put the bean both in mvc-dispatcher-servlet.xml configuration and in beans.xml the result is the same).

<kie:kmodule id="spring_module">

<kie:kbase name="rules" packages="com.my.sample.drools.rulespackage">

<kie:ksession name="ksession-rules" type="stateless">

</kie:ksession>

</kie:kbase>

</kie:kmodule>

I have this package "com.my.sample.drools.rulespackage" with a simple and tested rule in it.

In my Controller class I am trying to autowire the KieSession bean to a field as follows:

@Controller

@RequestMapping(value = "/")

public class BaseController extends AbstractController {

private static final Logger log = Logger.getLogger(BaseController.class);

@Autowired

@KSession("ksession-rules")

KieSession mySession;

.............

}

I tryed with @Inject instead of spring's @Autowire, the result is the same.

I am using the following Drools dependencies with their versions:
drools-core - 6.0.0.FINAL; drools-compiler - 6.0.0.FINAL; kie-spring - 6.0.0.FINAL; (I am trying to keep it simple as my first integration try.)

The spring version that I am using is 3.2.4.RELEASE.

I debugged KModuleBeanFactoryPostProcessor and I can clearly see that an object tree with KieModuleModelImpl, KieBaseModelImpl, KieSessionModelImpl,

with the corresponding details that I entered in the configuration above (packages, name, type, etc.) is created!. However it seems that a KieSession bean is not registered
spring's container.

What I do wrong? Can anyone please help?

Thanks in advance!
Best Regards,

Milen
