JSP Implicit Objects are also called pre-defined variables. JSP Implicit Objects are the Java objects that the JSP Container makes available to developers in each page and developer can call them directly without being explicitly declared. Q.4 Which are the Implicit objects in JSP? Override jspDestroy when you need to perform any cleanup, such as releasing database connections or closing open files. The jspDestroy() method is the JSP equivalent of the destroy method for servlets. The destruction phase of the JSP life cycle represents when a JSP is being removed from use by a container. JSP Execution: Whenever a browser requests a JSP and the page has been loaded and initialized, the JSP engine invokes the _jspService() method in the JSP. JSP Initialization: it is performed only once and as with the servlet init method, you generally initialize database connections, open files in the jspInit method. If the page has never been compiled, or if the JSP has been modified since it was last compiled, the JSP engine compiles the page. JSP Compilation: When a browser asks for a JSP, the JSP engine first checks to see whether it needs to compile the page.

This is done when the first request to the JSP page is made. Translation phase: in this JSP pages get translated to servlet code. Static HTML: Regular HTML, of course, cannot contain dynamic information. JavaScript: JavaScript can generate HTML dynamically on the client but can hardly interact with the web server to perform complex tasks like database access and image processing etc. Server-Side Includes (SSI): SSI is really only intended for simple inclusions, not for “real” programs that use form data, make database connections, and the like. Pure Servlets: It is more convenient to write (and to modify!) regular HTML than to have plenty of println statements that generate the HTML.

Second, it is portable to other operating systems and non-Microsoft Web servers.

Active Server Pages (ASP): The dynamic part is written in Java, not Visual Basic or other MS specific language, so it is more powerful and easier to use. Q.2 What are the advantages of using JSP over other technologies? JSP does not require additional files like java class files, web.xml etcĥ) JSP is built on Java technology, so it is platform independent.

In JSP, we can use a lot of tags such as action tags, JSTL, custom tags etc.

The servlet code needs to be updated and recompiled if we have to change the look and feel of the application. If JSP page is modified, we don’t need to recompile and redeploy the project. In servlet technology, we mix our business logic with the presentation logic.ģ) Fast Development: No need to recompile and redeploy

JSP can be easily managed because we can easily separate our business logic with presentation logic. In addition to, we can use implicit objects, predefined tags, expression language and Custom tags in JSP, that makes JSP development easy. We can use all the features of a servlet in JSP. JSP technology is the extension to servlet technology.
