EJB containers
An EJB server is a container for one or more EJB containers. An EJB server manages and coordinates allocation of EJB application resources, J2EE naming functionality, communication with remote resources, etc. An EJB container manages the actual EJBs including their lifecycle, object pooling, security, transactions, etc. The EJB container is all about concentrating user transaction requests into a shared database. The application server is the modern TP monitor, and the EJB is where the transactional interaction with the database happens. Find information about Enterprise JavaBeans (EJB) containers and how to properly contain transactions in a shared database.
