Cannot issue fireUntilHalt when using persisted session ------------------------------------------------------- Key: DROOLS-507 URL: https://issues.jboss.org/browse/DROOLS-507 Project: Drools Issue Type: Feature Request Affects Versions: 6.1.0.Beta3 Environment: Mac OSX Maverick, Spring 4.0.1 Reporter: Roger Lefebvre Assignee: Mark Proctor Generating the following exception when using runUntilHalt() with persistence. Exception in thread "SimpleAsyncTaskExecutor-1" java.lang.UnsupportedOperationException: Command session.fireUntilHalt(); cannot be issued on a persisted session at org.drools.persistence.SingleSessionCommandService$TransactionInterceptor.execute(SingleSessionCommandService.java:474) at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:353) at org.drools.core.command.impl.CommandBasedStatefulKnowledgeSession.fireUntilHalt(CommandBasedStatefulKnowledgeSession.java:272) at com.s.c.m.CallHandler$RunEngine.run(CallHandler.java:115) at java.lang.Thread.run(Thread.java:722) Persistence and KieSession defined in Spring as follows: <!-- provides KnowledgeStoreService implementation --> <kie:kstore id="kstore"/> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ruleEngine" /> <property name="username" value="xxxxxx" /> <property name="password" value="yyyyyyyy" /> </bean> <bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="persistenceUnitName" value="org.drools.persistence.jpa.local"/> </bean> <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="emf"/> </bean> <kie:kmodule id="callManagerModule"> <kie:kbase name="commandKBase" packages="rules.command" eventProcessingMode="stream"> <kie:ksession name="commandEngine" type="stateful"></kie:ksession> </kie:kbase> <kie:kbase name="campaignKBase" packages="rules.campaign.*" eventProcessingMode="stream" equalsBehavior="equality"> <kie:ksession name="campaignEngine" type="stateful" > <kie:consoleLogger/> <kie:configuration> <kie:jpa-persistence> <kie:transaction-manager ref="txManager"/> <kie:entity-manager-factory ref="emf"/> </kie:jpa-persistence> </kie:configuration> </kie:ksession> </kie:kbase> </kie:kmodule> <bean id="taskExecutor" class="org.springframework.core.task.SimpleAsyncTaskExecutor"> <property name="daemon" value="true"/> </bean> <bean id="campaignHandler" class="com.s.c.m.CallHandler" init-method="init"> <constructor-arg type="org.springframework.core.task.TaskExecutor" ref="taskExecutor"/> </bean> I invoke fireUntilHalt method as follows: private TaskExecutor taskExecutor; public CampaignCallHandler(TaskExecutor taskExecutor) { this.taskExecutor = taskExecutor; } public void init() { taskExecutor.execute(new RunEngine()); } class RunEngine implements Runnable { @Override public void run() { campaignEngine.fireUntilHalt(); } } NOTE: This occurs on a new system where nothing has been persisted to the database. In other words, there isn't a session available to be loaded. I have yet to have success reloading a session - that is a separate issue that I believe DROOLS-422 partially identifies.
