Web and EJB Containers
Containers provide runtime support for application components. Application components use
the protocols and methods of the container to access other application components and services
provided by the server. The Enterprise Server provides an application client container, an
applet container, a Web container, and an EJB container. For a diagram that shows the
containers, see the section
“Enterprise Server Overview” on page 23.
