Roger Lefebvre updated DROOLS-507:
----------------------------------

    Description: 
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.
