Web Servlets and JSP
3 days Course
Course Description
Discover Sun’s cutting edge technologies for building backend Web applications, in a 3 days
course dealing with Servlets and JSP. We begin with a quick overview of Web basics and
server side programming, followed by an introduction to J2EE Web Applications and Java
Servlets. We then deal with the technology’s pros and cons and explore its commonly used
features, including request manipulations, threading issues, session tracking and cookies. Once
students are comfortable with the world of Servlets, we continue our journey by looking at things
from the JSP point of view. We teach the various nuances of JSP by comparing it to its
ancestor, and learn to optimize our applications using Java Beans.
