Introducing Enterprise Java Application Architecture and Design - Pro Java EE Spring Patterns - page 7

As shown in Figure 1-5, there are two server-side containers:
• The web container hosts the presentation components such as Java Server Pages
( JSP) and servlets. These components also interact with the EJB container using
remoting protocols.
• The EJB container manages the execution of Enterprise JavaBeans (EJB) compo-
nents.
Figure 1-5. Java EE platform architecture
On the client side, the application client is a core Java application that connects to
the EJB container over the network. The web browser, on the other hand, generally inter-
acts with the web container using the HTTP protocol. The EJB and web containers
together form the Java EE application server. The server in turn is hosted on the Java
Virtual Machine ( JVM).
