need help on transaction management

[dreuzel]

using jboss 4.2.2.ga, seam 2.0.0.ga ,jta, enterprise management

I need transactionmanagement, but not with the classical helpers
container transaction mangement commits or rollsback the transaction
at the end , leading to timeouts and rolling back multiple correct transactions.


I handle thousands of [independent] updates in a loop,
every item in the loop is individualy commited or rolled back.

seam inects me the entityManger
em
I can get the session em.getdelegate()

as i do not want to setup container Transactions, nor the overall transaction rollback or timeout, I suspend potential active transactions
and do not create new transactions automaticaly

@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) //NOTSUPPORTES suspend all active transactions

I suppose the aboce is correct


within the loop I do not get transactions synchronised with the
entity session manager

loop{
 ses =(Session) em.getDelegate();
 txn=ses.getTransaction();//get transa
 //txn= ses.beginTransact
 txn.begin();

complains: Could not register synchronization for container transaction

switching to bean transactions

@TransactionManagement(TransactionManagementType.BEAN)

complains for bean problems :Could not register synchronization for container transaction bean managed transaction




any Ideas of how to manualy controll the EntityManager transactions ?
all help is welcome
