What exactly is J2EE? I am working with Servlets, JSP, Beans, JDBC and MVC on Tomcat but never did any work with EJB. Can I say I work on some J2EE or is J2EE only EJB and other stuff that is on WebLogic, WebsPhere and JBoss?
Servlets and JSP are part of Java EE (the web tier part). EJB is another part of Java EE (the business tier). Tomcat is a servlet container; it only supports servlets and JSP, not EJB. Weblogic, Websphere and JBoss also support EJB.
