Spring Modules 08a + Jbpm 3.2.6 "Session is closed" hibernate exception.

[eren.aykin]

Hi all,

I am having a hard time configuring the spring-modules jbpmTemplate. I am using Spring ver. 2.5.6.

When I execute the following code:

jbpmTemplate.execute(new JbpmCallback() {	    	    
            public Object doInJbpm(JbpmContext context) {
            GraphSession gSession = context.getGraphSession();
            gSession.saveProcessDefinition(jbpmTemplate.getProcessDefinition());
          ...
             ProcessInstance processInstance = context.newProcessInstanceForUpdate("x");
                 ContextInstance contextInstance = processInstance.getContextInstance();
                 ...	
                 context.save(processInstance);
                 
                ...
                 return null; // I get the error after this line is executed 
            }
        });

I get :

my jbpm.cfg.xml contains:

<jbpm-configuration>

  <jbpm-context>
   
   <service name="persistence">
      <factory>
        <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">

      </factory>
    </service>
   
   <service name="tx" factory="org.jbpm.tx.TxServiceFactory"/>
  	
  
  </jbpm-context>

and my application context contains:

<bean id="jbpmSessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" autowire-candidate="false" name="jbpmSessionFactory">
		
		<property name="dataSource" ref="jbpmDataSource" />
		<property name="configLocation" value="classpath:hibernate.jbpm.cfg.xml" />
		
.... 

<bean id="jbpmDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.jbpm.url}"/>
	</bean>

...

 <bean id="processDefinition"
          class="org.springmodules.workflow.jbpm31.definition.ProcessDefinitionFactoryBean">
          <property name="definitionLocation" value="classpath:processdefinition.xml"></property>
    </bean>

	<bean id="jbpmConfiguration"

		  <property name="configuration" value="classpath:jbpm.cfg.xml" />
		  <property name="createSchema" value="false" />
		  <property name="processDefinitions">
               <list>
                    <ref local="processDefinition"></ref>  
               </list>
          </property>
          <property name="processDefinitionsResources">
     		  <list>
      			  <value>classpath:reportee.processdefinition.xml</value>
     		  </list>
   		  </property>
          
	</bean>

	<bean id="jbpmTemplate" class="org.springmodules.workflow.jbpm31.JbpmTemplate" > 
		<constructor-arg index="0" ref="jbpmConfiguration" />	
		<constructor-arg index="1" ref="processDefinition"/>
	</bean>  
	
        ...

I guess both spring module and jbpm context are trying to close the session. Would you please help me to understand why am I getting this error?
