Web Application Development with Servlets & JSP

May 10-14 2010, JHU Dorsey Center, Elkridge MD

This page describes the public (open enrollment) training courses on JSP and servlet programming to be held May 10-14 at the Johns Hopkins Dorsey Center in Elkridge, MD (co-sponsored by the Johns Hopkins Engineering for Professionals program). The entire course is personally developed and taught by leading JSP/servlet developer, speaker, and author Marty Hall. No contract instructor teaching someone else's materials! Marty has taught this course onsite for dozens of organizations in the US, Canada, Mexico, Australia, Japan, Puerto Rico, and the Philippines, all to rave reviews.

If you are looking for customized Java EE training courses taught on-site at your company, please see this page.

Register Early! Five of Marty's previous public short courses were full, so reserve your spot today. Registrations are taken in the order they are received.

Overview

The Java EE Platform has become the technology of choice for developing professional e-commerce applications, interactive Web sites, and Web-enabled applications and services. Servlet and JSP technology is the foundation of this platform: it provides the link between servers and Web clients (browsers, cell phones, Ajax applications, etc.). This course provides a practical, hands-on introduction to building Web applications in Java. It gives details on the most important topics, surveys more advanced or lesser-used topics, stresses best practices, and gives plenty of working examples.

Marty normally runs on-site training courses at customer locations. This is easier administratively, is better for clients since the topics can be customized, and is more cost effective for students since no travel is required. However, due to demand from those who do not have enough students for an on-site course, Marty will be running public (open enrollment) servlet and JSP training courses February 1-5 in San Francisco CA and May 10-14 in Elkridge MD.

The course is developed and taught by Marty Hall, and experienced developer, award-winning instructor, popular conference speaker (5 times at JavaOne), and author of several popular J2EE books. The course is based on the second edition of Marty's book Core Servlets and JavaServer Pages, and each student will receive their own copy as well as a bound student notebook.

Venues

The west coast version of the course will be held at the Marakana Training Center in San Francisco, California. This is a modern, comfortable venue with separate computers for each student, fast internet connections, and with coffee, snacks, and meals included. For northern California residents, the location is easily accessible by driving (free parking!) or mass transit. For out-of-town students, there are many nearby hotels and we provide free taxi vouchers for going between the hotel and the training center.

The east coast version of the course will be held at the Johns Hopkins Dorsey Center in Elkridge, Maryland. This is also a modern, comfortable venue with separate computers for each student, fast internet connections, and with coffee, snacks, and meals included. For Maryland residents, the location is centrally located 5 minutes from BWI airport and has plenty of free parking. For out-of-town students, there are many hotels within 1 mile.

Registration

The five-day course costs $2395 per student and includes an extensive course notebook, a commercial textbook, exercises, exercise solutions, breakfast, snacks, and lunch. Compare this price to courses from Sun, Learning Tree, GlobalKnowledge, and Oracle University that cost around $2400 for four-day courses and $3000 for five-day courses that do not include textbooks or meals. Besides, those courses almost always use an unknown instructor who did not develop the course materials and often lacks significant real-world development experience.

To register, fill out and send in the course registration form. Space is limited: five previous offerings of coreservlets.com courses were full. Bonus: Register at least a week in advance and get a $50 gift certificate from amazon.com.

Prerequisites

The course consists of an approximately equal mixture of lecture and hands-on lab time. The course assumes that all students already have at least moderate previous Java experience, but not necessarily any experience with server-side Java or HTTP. Although the course will use Java 6, previous experience with earlier Java versions is sufficient. However, the course will definitely move too fast for those with little or no previous experience with any Java version. Working knowledge of HTML is helpful but not absolutely required.
