Java Training : Servlets and JSP Quick Start

Servlets and JSP Quick Start

Java Training Overview

This course provides a quick introduction to Servlets and JSP, a key server-side Java Web technology. It is useful in situations where developers need to be familiar with it, but don't need to know all of their many details. It is usually used along with other course materials to make a longer course.

The course is hands on with a good selection of labs. It will provide the information needed to be comfortable working directly with Servlets and JSPs, or with other frameworks that build on them.
