J2EE
Distributed Multitiered Applications (Architecture)
Web Pages(HTML) -> JSP, Servlet(Spring MVC) -> EJB(Spring Bean) -> JDBC(Hibernate)
Java EE Components
- Application clients and applets are (client) components that run on the client.
- Java Servlet, JavaServer Faces, and JavaServer Pages (JSP) technology components are web components that run on the server.
- EJB components (enterprise beans) are business components that run on the server.
Java EE Container
Containers are the interface between a component and the low-level, platform-specific functionality that supports the component. Before it can be executed, a web, enterprise bean, or application client component must be assembled into a Java EE module and deployed into its container.
EXAMPLE:
- Tomcat, Jetty -> JSP/Servlet Container
- WebLogic, WebSphere, JBoss, GlassFish -> EJB Container
