J2EE Enterprise Java Beans

• Overview
• An enterprise bean is a server-side software
  component that can be deployed in a distributed
  multitier environment.
• An enterprise bean can compose one or more Java
  objects because a component may be more than just
  a simple object.
• Regardless of an enterprise beans composition,
  the clients of the bean deal with a single
  exposed component interface. This interface, as
  well as the enterprise bean itself, must conform
  to the EJB specification.
• The specification requires that your beans expose
  a few required methods
