What is an EJB component?  EJB components are the Java component model for enterprise applications.

  * EJB components are Java server-side components that are based on   standard distributed object  technologies, CORBA  and RMI.EJB components are always distributed, which makes them fundamentally different from standard JavaBeans components.

  * EJB  components  provide the  business  logic part of   an application. They are not concerned with presentation issues, and therefore must be used in conjunction  with  display technologies like  servlets  or  JavaServer  Pages (JSP)  technology  for HTML clients, or Java applications that use technologies such as AWT or Swing.

  * Application  servers that implement the EJB specification can simplify business application systems by providing  services  that handle the complexities:  security, resource pooling, persistence,concurrency, and transactional integrity.
