How JSP is different from Servlets?

-

JSP

 Java Server Pages (JSP) is a server-side programming technology that enables the creation of dynamic, platform-independent method for building Web-based applications. JSP have access to the entire family of Java APIs, including the JDBC API to access enterprise databases. It can be thought of as an extension to servlet because it provides more functionality than servlet. A JSP page consists of HTML tags and JSP tags. The JSP pages are easier to maintain than servlet because we can separate designing and development.

JSP

JSP is a collection of technologies developed by Sun Microsystems. It is used to develop web pages by inserting Java code into the HTML pages by making special JSP tags. It can consist of either HTML or XML (combination of both is also possible) with JSP Actions and commands. The full form of JSP is Java Server Pages.

Servlet

Servlet is a Java technology that is managed by a container called a servlet engine. It generates dynamic content and interacts with the client through Request and Response. Servlet extends the functionality of a web server. Though servlets can respond to many types of requests, they generally implement web containers for hosting any website on web server. Therefore, it is qualified as a server-side servlet web API.

KEY DIFFERENCES

  • Servlet can accept all protocol requests, including HTTP, while JSP can only accept HTTP requests.
  • In MVC architecture, servlet works as a controller while JSP works as a view for displaying output.
  • Servlet should be used when there is more data processing involved whereas, JSP is generally used when there is less involvement of data processing.
  • Servlets run faster than JSP, on the other hand JSP runs slower than servlet as it takes time to compile the program and convert into servlets.
  • You can override the service() method in servlet but, in JSP, you can’t override the service() method.
  • In Servlet, you have to implement both business logic and presentation logic in the single file. Whereas in JSP, business logic is split from presentation logic using JavaBeans.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

  b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

Protection of Public Order and Decency  The internet is highly capable of being a saturated and versatile medium at the same time. Its reach is very vast and due to its multimedia capability, its impact can be immediate and profound.
