The entire workshop is primarily divided into three main modules
Module One
[top]
Objective: To learn main technologies and tools involved in web development.
During the first part of workshop, the trainee will learn about the main
components and workflow of a typical web application by implementing a couple of
simple use cases. Testing will be done using Junit. Building and deployment
will be done using Ant. Upon completion of the module, the trainee will be able
to develop a simple application using JSP, servlets, and Eclipse and deploy it
on Tomcat
