Subject RE: daomanager doesn't rollback transaction?
Date Wed, 02 Aug 2006 13:52:30 GMT
If you have an external transaction manager set up, the *Transaction calls are effectively
ignored because you've told iBATIS to leave things up to the external manager.

Are you intending to use Websphere as the external manager or Spring?

I don't know much about Websphere, but for Spring you would need to configure the transaction
handling in your application context.  The easiest way, which requires no Java code changes,
is through declarative transactions:


The various txn options are defined here:


The basic idea is that you wrap your  DAO bean with a TransactionProxyFactoryBean and configure
it to use transactions on the methods you want to handle as transactions.  Then Spring intercepts
calls to the DAO and treats them as transactions according to how you've configured things.

Subject: RE: daomanager doesn't rollback transaction?
I'm using oracle9 with ibatis sqlmap 2.1.7 and
deploying on websphere application server and have the
transaction set as external and I'm using spring 2.0
following is my code for the transaction. It's able to
delete but when an exception is thrown after deletion,
it doesn't rollback, looking forward to your opinions


if(p.getChildren() != null && p.getChildren().size()
for (Iterator it=p.getChildren().iterator();
it.hasNext(); ) 
Child child= (Child)it.next();
child.setParentSeqNum(	p.getSeqNum());
