Question on EntityManager.flush()

carstenrudat Feb 21, 2007 9:42 AM

Hi All,

I have a SFSB-Method "print" (no special transaction-attribute -> REQUIRED) that works as an entry point for printing. Printing is done by Eclipse-BIRT but there is a "prePrintProcess" which put some data in a table "printdata" for BIRT.

The problem is, that the BIRT-Process is called within the method "print" and so the are no data in "printdata", because the transaction has not been commited, so far.

So, I tried to encapsulate the "prePrintProcess" in a separate method of the SFSB and set an annotation @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW). Before the method "prePrintProcess" returns, I call "myEntityManger.flush()". But after this method "prePrintProcess" there is still no data in "printdata" :-(.

What should I do (besides BMT)?

Thanks for any help!

Carsten

Hi Carsten,

there is no new TX created when you call method within the same bean.
You have to implement your prePrintProcess in another bean (layer) and
mark as REQUIRES_NEW. Then will be the new TX created and commited.

Altertnatively you can do:
ctx.getBusinessObject(MyInterface.class).prePrintProcess();

This will route the call through the container.
