 Hi All,

I am using JBPM with Spring and Hibernate. I am getting the following exception while getting the variables using executionImpl and is as follows:

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: org.jbpm.pvm.internal.model.ExecutionImpl.variables, no session or session was closed
org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358)
org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350)
org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:343)
org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86)
org.hibernate.collection.PersistentMap.entrySet(PersistentMap.java:242)
org.jbpm.pvm.internal.model.ScopeInstanceImpl.getVariables(ScopeInstanceImpl.java:237)
com.jpmc.speadd.service.impl.SpeaddWorkFlow.StartWorkFlow(SpeaddWorkFlow.java:245)
 
 My JBPM-config file snippet:
 



<command-service name=+"txRequiredCommandService">  <retry-interceptor />  <environment-interceptor /> <spring-transaction-interceptor /> </command-service> 



<


transaction-context>


<transaction type=+"spring"+/>


<repository-session/>


<db-session/> 


<message-session/>


<timer-session/>


<history-sessions>


<object class=+"org.jbpm.pvm.internal.history.HistorySessionImpl"+/>


</history-sessions>



<!--Need to set explicitly that we don't want jbpm to create sessions
-->



<hibernate-session current=+"true"+ close=+"false"/+>


</transaction-context>



Can you please let me know how can i solve the same? Please send a response as soon as possible.

With Regards,
Felix K Jose
