spring Transaction exception handling

[vijay jacob]

Bascically with spring txn management . We can annotate the service layer class with @Transactional.

Also i have annotated my dao layer class with @repository to make checked exception to uncehcked exception

Now when a runtimeexception is encoutered by the service layer class it will rollback.


My question how do we go about the exception handling. I will have to put some error message to UI .So i need to capture the exception .

How do i go about it.
