JSP (JavaServer Pages) & Servlets Training Course

Overview

The JSP and Servlets training course teaches beginning and early intermediate Java developers how to build database-driven Web applications using JavaServer Pages and Java Servlets.

Objectives

At the end of JSP Training course, participants will be able to:

• Design and build robust and maintainable web applications
• Create dynamic HTML content with Servlets and JavaServer Pages, using the JSP Standard Tag Library (JSTL)
• Make Servlets and JSP work together cleanly
• Use JSTL and other Custom Tag Libraries to separate Java and HTML code
• Access databases with JDBC
• Use Enterprise JavaBeans effectively from Servlets and JSP

Audience - Architects, Designers, Consultants & Developers.

Duration - 5 Days

Prerequisites - All participants should be fluent in HTML and have a prior knowledge of object-oriented or object-based programming, as well as some knowledge of SQL and relational databases.
