Method Detail

createEntityManagerEntry

protected org.apache.deltaspike.jpa.impl.transaction.context.EntityManagerEntry createEntityManagerEntry(javax.persistence.EntityManager entityManager,
                                                                                                         Class<? extends Annotation> qualifier)

Overrides:

createEntityManagerEntry in class org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy

applyTransactionTimeout

protected void applyTransactionTimeout()

getDefaultTransactionTimeoutInSeconds

protected Integer getDefaultTransactionTimeoutInSeconds()

lazyInit

protected void lazyInit()

createDefaultTransactionConfig

protected org.apache.deltaspike.jpa.api.transaction.TransactionConfig createDefaultTransactionConfig()

getTransaction

protected javax.persistence.EntityTransaction getTransaction(org.apache.deltaspike.jpa.impl.transaction.context.EntityManagerEntry entityManagerEntry)

Overrides:

getTransaction in class org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy

beforeProceed

protected void beforeProceed(javax.interceptor.InvocationContext invocationContext,
                             org.apache.deltaspike.jpa.impl.transaction.context.EntityManagerEntry entityManagerEntry,
                             javax.persistence.EntityTransaction transaction)

Needed because the EntityManager might get created outside of the UserTransaction (e.g. depending on the implementation of the producer). Can't be in BeanManagedUserTransactionStrategy.UserTransactionAdapter#begin() because ResourceLocalTransactionStrategy needs to do

 
 if (!transaction.isActive())
 
 {
 
   transaction.begin();
 
 }
 
 

for the EntityTransaction of every EntityManager and BeanManagedUserTransactionStrategy.UserTransactionAdapter#isActive() can only use the status information of the UserTransaction and therefore BeanManagedUserTransactionStrategy.UserTransactionAdapter#begin() will only executed once, but EntityManager.joinTransaction() needs to be called for every EntityManager.

Overrides:

beforeProceed in class org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy

Parameters:

invocationContext - current invocation-context

entityManagerEntry - entry of the current entity-manager

transaction - current JTA transaction wrapped in an EntityTransaction adapter

resolveUserTransaction

protected UserTransaction resolveUserTransaction()
