How to jsp is process in web application ?
Here we discuss how a jsp page is processed in web application when it is requested by the users-
1. First time JSP page is loaded by the JSP container which is also called jsp engine(Where the JSPs complied) .Here the Jsp generated and complied java code which is called servlet code . This code is loaded in servlet engine. This process is occurs on translation time . It is important to note that this occurs only the first time when jsp is requested.
What are the differences between jsp and servlet ?
Both techniques are used to handle the web request in java or creating dynamic content with web pages-
Servlets- servlets executed on server and acting as a middle layer between clients and lower level applications.servlets contain the html code in java program. servlets are well suited to deciding how to handle client requests and invoke them but are not well suited for generating contents.Here markup code is harder to implement or maintain in web application. Developers need more experience of java to written servlets.
JSP- Jsp designed and developed less like programs and more like web pages.Generating html is much easier than servlets. Java code is written in html program or in html code.Jsp can use java bean with specified scope(Session,Request).
What is JSP ?
JSP stands for java server pages. JSP is server sided language which execute only server .The goal of the JSP specification is , creation and management of dynamic web pages. it provide more convenient way than servlets.JSP pages combine static markup like HTML,XML with scripting tags. The main thing is that each server page is translated into servlet the first time invoked.
Version of JSP 1.0 released in September 1999 and JSP 1.2 released in December 1999.
