Re: [rules-users] Persistence in Drools 6

[dush...@gmail.com]

Hi Jean Philippe,

I managed to get around using kie-spring with KieScanner integration. if you
use exact configuration as below you will be able to setup persistence,
scanner together with spring 6.1.0. 


<bean id="kReleaseId" class="org.drools.compiler.kproject.ReleaseIdImpl">
                <constructor-arg index="0" value="xx.yy.zz" />
                <constructor-arg index="1" value="artifiactl" />
                <constructor-arg index=&quot;2&quot; value=&quot;&lt;b>LATEST*" 
/>
</bean>

<kie:kmodule id="kModule">
                <kie:kbase name=&quot;&lt;b>defaultKieBase*">
                        <kie:ksession name=&quot;&lt;b>defaultKieSession*">
                                <kie:configuration>
                                        <kie:jpa-persistence>
                                                <kie:transaction-manager 
ref="txManager" />
                                                <kie:entity-manager-factory 
ref="myEmf" />
                                        </kie:jpa-persistence>
                                </kie:configuration>
                        </kie:ksession>
                </kie:kbase>
        </kie:kmodule>

<kie:environment id="env">
                <kie:entity-manager-factory ref="myEmf" />
                <kie:transaction-manager ref="txManager" />
</kie:environment>

<bean id="kiePostProcessor"
class="org.kie.spring.KModuleBeanFactoryPostProcessor">
                <property name="releaseId" ref="kReleaseId" />
</bean>

In a separate bean execute below code to set-up scanner (can use
init-method).

                ReleaseId releaseId = (ReleaseId)
applicationContext.getBean("kReleaseId");
                KieServices ks = KieServices.Factory.get();
                KieContainer kieContainer = ks.newKieContainer(releaseId);
                KieScanner kieScanner = ks.newKieScanner(kieContainer);
                //kieScanner.start(5000L);
                kieScanner.scanNow();


Note highlighted text snippets. use them as is.  Caveat is , when you set-up
kbase with a release id and kiecontainer, default  beans created by spring
would be ignored. instead   container would create default kbase and a
ksession(s)(stateful,stateless) for you. those names should be included as
highlighted.

This is totally a workaround I found while debugging and yet to test if
scanner functionality is working properly.
