Question :What is the difference between a Server, a Container, and a
Connector? (EJB)
Answer :An EJB server is an application, usually a product such as BEA WebLogic,
that provides (or should provide) for concurrent client connections and
manages system resources such as threads, processes, memory, database
connections, network connections, etc.
An EJB container runs inside (or within) an EJB server, and provides
deployed EJB beans with transaction and security management, etc. The
EJB container insulates an EJB bean from the specifics of an underlying EJB
server by providing a simple, standard API between the EJB bean and its
container.
A Connector provides the ability for any Enterprise Information System
(EIS) to plug into any EJB server which supports the Connector
architecture. See http://java.sun.com/j2ee/connector/ for more indepth
information on Connectors.
