Java Server Page (JSP) is a web programming language that runs on the Java platform, and is part of Java 2 Enterprise Edition technology (J2EE). JSP is very fit and strong to handle the presentation on the web with the support of the Application Programming Interface (API) complete and portability and provides the means to create an application that separates business logic (the system), presentation and data.
JSP was created to simplify the presentation layer that is dynamic in a way to separate the contents of which are static with dynamic content on a page. JSP is designed as a presentation layer of a web application, which adds JSP Java program on a web page that is static.
JSP pages also contain elements that allow the server to insert dynamic content in pages. JSP element can be used for various purposes, such as retrieving information from the database. JSP set a number of standard elements that are useful for web applications, such as accessing JAVABEAN component.
JAVABEAN
JAVABEAN is a component that is reusable in java. JAVABEAN used to manage data between the client application or applet and components running on the J2EE server or between server components and database.
Java Bean components have instance variables and get and set methods for accessing data stored in instance variables. JAVABEAN component has a simple design and implementation. Java Bean components to manage user input and send the input to enterprise beans running on the business tier for processing. The use of JAVABEAN application will be easier if compiled with some Java-based applications a higher level of code used. For some applications, the Java Bean needs some code and character values that will be used as the opening code in making a program. With the opening code, the JAVABEAN applications to work more optimally to design a simple application, before we make some advanced programs, such as applications contained in C.
