Java EE 8 Cookbook

How it works...

The first thing we did was mark our bean to hold states and have its transactions managed by the server:

@Stateful@TransactionManagementpublic class UserBean {    ...}

What happens then? If you note, no method that deals with adding or removing stuff does any transaction management. But they are still managed:

 Transaction started 1 added Transaction will be commited Transaction commited? true

So you have all the transaction intelligence without writing a single line of transaction stuff.

It will transact even when the bean would releases its resources:

 Transaction started User logout. Resources will be released. UserBean will be destroyed Transaction will be commited Transaction commited? true
