How to handle transaction?

[Winster]

Hi,

I want to store entities into database using
"delegator.create(genericValue)". I want to wrap this operation in a
transaction so that if any of the entity insert operation fails, rollback
all previous insert operations. How can I do that in OFBiz?

Thanks in advance

If the operation is within a service, you don't need to worry about
handling transactions - the service engine does that for you.

Thanks Adrian. Currently I am invoking the method from groovy directly. So,
I need to change the way I did, right?

How did you invoke Groovy?

Hello Winster,

You need to call the service as :

dispatcher.runSync("MyService", map);

This way a new transaction is automatically created if there is no current
transaction in place.  If there was a transaction (in case of service
chain, one service calling to another service) a new transaction is not
created (unless in service definition you have mentioned to create a new
transaction always).
