    Task activity failure to save history data of the task

    Aurelijus Janeliunas Newbie

      Hi,

       

      We have problems with task execution in our SEAM-SPRING-JBPM+JBOSS hybrid enviroment. It fails to save history task due transaction failures. The exception looks like:

       

      2011-02-15 15:13:05,792 WARN  [org.hibernate.util.JDBCExceptionReporter] (WorkManager(2)-5) SQL Error: 0, SQLState: null

      2011-02-15 15:13:05,792 ERROR [org.hibernate.util.JDBCExceptionReporter] (WorkManager(2)-5) Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:beaa:4d5a79d2:163e status: ActionStatus.ABORT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:beaa:4d5a79d2:163e status: ActionStatus.ABORT_ONLY >)

      2011-02-15 15:13:05,797 WARN  [org.hibernate.util.JDBCExceptionReporter] (WorkManager(2)-5) SQL Error: 0, SQLState: null

      2011-02-15 15:13:05,797 ERROR [org.hibernate.util.JDBCExceptionReporter] (WorkManager(2)-5) Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:beaa:4d5a79d2:163e status: ActionStatus.ABORT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: 7f000001:beaa:4d5a79d2:163e status: ActionStatus.ABORT_ONLY >)

       

      I have exact place where it fails in JBPM core:

       

      TaskActivity.execute(ExecutionImpl execution) --> HistoryEvent.fire(new TaskActivityStart(task), execution) --> TaskActivityStart.process() -->  dbSession.save(historyActivityInstance)

       

      We use most common approach to reach JBPM functionality in Seam. We inject processEngine spring bean in seam enviroment:

      • Spring configuration:

      <?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:seam="http://jboss.com/products/seam/spring-seam"

             xmlns:jee="http://www.springframework.org/schema/jee"

             xmlns:aop="http://www.springframework.org/schema/aop"

             xmlns:oxm="http://www.springframework.org/schema/oxm"

       

             xsi:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

             http://jboss.com/products/seam/spring-seam http://jboss.com/products/seam/spring-seam-2.2.xsd

             http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

             http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd">

           <!-- jBPM beans. --> 

          <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper"/>

          <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine"/>

      </beans>     

      • In Seam side we start process instance:

       

          private Object _start(String key, String id, Map<String, Object> data){

              if ( StringUtils.isEmpty(key) || StringUtils.isEmpty(id) ){

                  return Boolean.FALSE;

              }

              //return execution service

              ExecutionService execService = _getExecutionService();

              //

              if ( execService == null ){

                  return Boolean.FALSE;

              }

              try {

                  //prepare data for jBPM start the process

                  Map<String,Object> _variables = new HashMap<String, Object>(0);

                  _variables.put("current", data);

                  //start the new process

                  execService.startProcessInstanceByKey(key, _variables, id);

                  return Boolean.TRUE;

              } catch (Exception e) {

                  logger.error("[OperationManagerImpl:_start] errors:", e);

              }

              return Boolean.FALSE;

          }

       

      Notice. All data placed in parameter "data" are implementing Serializable interface. So, we don't have any problems with variable serialisaztion inside JBPM core.

      • Whole application use spring style transaction manager (SEAM and JBPM).

      Any ideas how to "erase" these exceptions from application?

       

      Best regards,

          Maybe you should expand your spring-configuration. I'm not an expert in this issue but I think there must be beans configured in a way like this:

           

               <bean id="sessionFactory"
                    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

                    <property name="configLocation" value="classpath:jbpm.hibernate.cfg.xml" />
                    <property name="dataSource" ref="dataSource" />
               </bean>

               <bean id="transactionManager"
                    class="org.springframework.orm.hibernate3.HibernateTransactionManager">

                    <property name="sessionFactory" ref="sessionFactory" />
                    <property name="dataSource" ref="dataSource" />
               </bean>

               <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
                    destroy-method="close">

                    <property name="driverClassName" value="YourDriver" />
                    <property name="url" value="someUrl" />
                    <property name="username" value="user" />
                    <property name="password" value="password" />
               </bean>

           

          But I don't use JBPM with Spring so I'm not confident at all.

            I have sessionFactory and dataSource configurations in my application. In fact, the other process instances with task tags are working correctly expect this one.
