This trail shows how to declare transactional properties for any POJO methods in an EJB 3.0 application and how transactions work for database operations.
Application Transactions
Application transaction is a long running transaction that spans across several method invocations in different threads. It especially useful in session-based web applications, where each transaction might involve a series of pages. In this trail, we will show how application tra 闃呰鍏ㄦ枃

Those beans are very useful in session-based web applications (e.g., a shopping cart).

Stateless Session Beans
This trail illustrates how to develop and use EJB 3.0 stateless session beans. Those beans can be used to build the programming interface between the middleware and the front-end servlets or rich UI clients.
