- 7. A Java servlet is a Java program that extends the capabilities of a server. Although servlets can respond to any types of requests, they most commonly implement applications hosted on Web servers.
- 8. The Smarter Way To Learn NetBeans is a software development platform written in java. The NetBeans Platform allows applications to be developed from a set of modular software components called modules. NetBeans is cross- platform and runs on Microsoft Windows, Mac OS X, Linux, Solaris and other platforms supporting a compatible JVM.
- 9. MV C One of the most common Design Patterns is Model- View-Controller (MVC) The model does all the computational work It is input/output free All communication with the model is via methods The controller tells the model what to do User input goes to the controller The view shows results; it is a “window” into the model The view can get results from the controller, or The view can get results directly from the model
- 10. Advantages of MVC One advantage is separation of concerns Computation is not intermixed with I/O Consequently, code is cleaner and easier to understand Another advantage is flexibility The GUI (if one is used) can be completely revamped without touching the model in any way Another big advantage is reusability The same model used for a servlet can equally well be used for an application or an applet (or by another process) MVC is widely used and recommended
- 11. MVC for servlets The model, as usual, does all the computational work, and no I/O The model can consist of multiple classes The servlet class (the one that extends HttpServlet) acts as the controller The servlet gives any relevant information from the user request to the model The servlet takes the results and passes them on to the view The view—that is, the HTML page that is returned to the user—is frequently created by JSP
