A modular 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. A modular container manages the actual EJBs including their lifecycle, object pooling, security, transactions, etc. The modular container is all about concentrating user transaction requests into a shared database.
