Re: [rules-users] Fuse ESB & Drools 6 problem

I'm testing the drools new version (6.1.0.Beta4) but I have a problem with the Stateful Drools Session. I have deployed in JBoss Fuse ESB the last versión of the drools (drools camel, jbpm, spring, etc), I have atached my camel context bundle (It's a maven project). This is my camel-context <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:kie="http://drools.org/schema/kie-spring" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://drools.org/schema/kie-spring http://drools.org/schema/kie-spring.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> <kie:kmodule id="kModule"> <kie:kbase name="rules" packages="rules"> <kie:ksession name="ksession1" type="stateful"> <!--<kie:batch> <kie:fire-all-rules/> </kie:batch> --> <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 class="org.postgresql.ds.PGPoolingDataSource" id="jbpm-ds"> <property name="serverName" value="localhost"></property> <property name="databaseName" value="drools"></property> <property name="portNumber" value="5432"></property> <property name="user" value="DWP"></property> <property name="password" value="DWP"></property> </bean> <bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="jbpm-ds"/> <property name="persistenceUnitName" value="org.jbpm.persistence.jpa.local"/> </bean> <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="myEmf"/> </bean> <bean id="kiePostProcessor" class="org.drools.osgi.spring.OsgiKModuleBeanFactoryPostProcessor"/> <bean id="fireALlRulesCommand" class="com.execute.command.FireAllRules"/> <camelContext xmlns="http://camel.apache.org/schema/spring"> <route trace="false" id="testRoute"> <from uri="timer:testRoute?period=10s"/> <to uri="log:message"/> <to uri="kie:ksession1?action=insertBody" id="AgeVerification"/> <bean method="fireAllRules" ref="fireALlRulesCommand"/> <to uri="kie:ksession1?action=execute"/> </route> </camelContext> </beans> As you can see it is an scenario where Drools is in an stateful session with persistence configured. The bundle is executed without errors but I want that Drools executes my rules each time that the route is executed ( fireUntilHalt mode but I wasn't able as seems that this command is not availble in a persisted environment ), for this reason I've created a bean with the command: fireAllRules and I use <to uri="kie:ksession1?action=execute"/> to execute the rules but the problem is that the rules are only executed the first time, only the first time and never in subsequents executions of the route. The persistece seems to work well ( I can see the datamodel created and populated as expeted in the DB ). However if I change to use stateless mode ( no persistence then ), the rules are executed each time that route is executed ( as expected ), and therefore I don´t need the command fireAllRules <bean method="fireAllRules" ref="fireALlRulesCommand"/> <to uri="kie:ksession1?action=execute"/> Questions: Is it possible to have a stateful fireUntilHalt drools session that keeps using the same knowledge session in subsequent camel route executions? If it is not possible, Can I have a stateful ( persisted )drools session and invoke "fireAllRules" whenever I make changes in the knowledge session ( new Facts are inserted )? I've deep dived into the web looking for examples or documentation of this scenario both in Spring and Blueprint. Does anyone of you have any pointers to documentation on the matter?
