OSIV (Open session in view) pattern is imlemented using filters... and it says:

When the request arrives, you start a database transaction and open a new persistence context. After the controller
has executed and the view has been rendered, you commit the database transaction.

My question is: controller is a servlet and filter code will come in picture immediately when servlet (controller) ends and before the Jsp is shown... ( and not after Jsp is shown as written in the above statement)... Is my understanding correct ?
