[RomaFramework-dev] R: transaction example

[Luca G. <luc...@as...>]

Hi,
Sorry for delay on reponse. You can use the power of JDO 2 standard in =
Roma.
You can handle more objects in your method and commit anything in a
transactional fashion.

Example:

PersistenceAspect tx =3D ObjectContext.getInstance().getComponent(
"TxPersistenceAspect" );
Try{
  tx.createObject( new Employee() );
  tx.createObject( new Invoice() );
  tx.commit();
} finally{
  tx.close();
}

TxPersistenceAspect is the component declared in Spring's
applicationContext.xml file.

Hope to be help
bye,
Luca Garulli

Oggetto: [RomaFramework-dev] transaction example

Hi, Roma developers,

I am a Roma newbie. Please ask where can I get the Roma database =
transaction
example to process two tables ? In hibernate or jdbc, I can set the =
entity's
attribute before post the transaction.Maybe my question is how can I =
code a
main(String[] args) method to call Roma's API, in order to save two =
records
into two tables in one transaction. Thanks.

wj
