I know how much I said, but it is not necessarily correct. J2EE: This thing represents two different things, one is a server software for Sun, paying attention is a specific software, not technology. The other is a java technology that is generally Sun, including JSP, servlet, javabean, ejb, etc. J2SE: I know, Sun's JDK has a specialistic version of the version of For electronics, called J2ME, used to develop applications such as mobile phones, PDA, J2SE is used for computers. Javabean: Popular speaking is to encapsulate a lot of function class, used to be called by other JSP, servlets, etc. EJB: More popular speaking, you can make your Javabean on multiple computers for you to call. Servlet: The UI design used to interact with the user through the HTTP protocol is too poor, and the JSP can achieve more convenient UI design. Struts: JSP mixed the web page and code, too mess, so Struts can help you separate JSP UI and logical parts. Hibernate: alternative to JDO???
