Introduction (cont...)

• JSP pages are executed by a program known as web

container or jsp container.

• A JSP page is internally converted to a servlet by the

server. That servlet processes the client request.

• JSP supports rapid development of database

applications.

• JSP is web server independent and platform

independent.

Introduction (cont...)

• JSP separates the dynamic content from the

static HTML content. So, a HTML developer

can work with HTML and a JSP developer

can include JSP code at a later point in time.

• Extension of a JSP page is .jsp.

• JSP is built on top of Servlet API.

code) and presentation logic (HTML).

• Difficult for maintaining web applications.

• Takes more time for development.

• JSP container is a program (special servlet)

which forwards the jsp page request to a

servlet container.
