TheWeb Container
TheWeb Container is a J2EE container that hosts web applications. The web container extends
theweb server functionality by providing developers the environment to run servlets and
JavaServerPages (JSP les).
The EJB Container
Enterprisebeans (EJB components) are Java programming language server components that
containbusiness logic. The EJB container provides local and remote access to enterprise beans.
Thereare three types of enterprise beans: session beans, entity beans, and message-driven
beans.Session beans represent transient objects and processes and typically are used by a single
client.Entity beans represent persistent data, typically maintained in a database.
Message-drivenbeans are used to pass messages asynchronously to application modules and
services.
Thecontainer is responsible for creating the enterprise bean, binding the enterprise bean to the
namingservice so other application components can access the enterprise bean, ensuring only
authorizedclients have access to the enterprise bean’s methods, saving the bean’sstate to
persistentstorage, caching the state of the bean, and activating or passivating the bean when
necessary.
