Course No. N/A

Java Enterprise Edition (Java EE 5) is a powerful platform for building web applications. The Java EE platform offers all the advantages of developing in Java plus a comprehensive suite of server-side technologies. This course tells participants what they need to know to design and build their own web applications. They’ll learn the details of the key Java EE technologies and how to leverage the strengths of each, with special focus on Servlets and JSP, and at the same time, they’ll cover the big picture of Java EE and how to design web applications that are robust, efficient and maintainable. If you want to deliver an application on the web, you’ll find this course essential.

The course begins with a discussion of web application architecture. A major part of the course is spent on Servlets and JavaServer Pages (JSP) with special focus on using the JSTL. It then covers JDBC, Java’s database access technology. The course concludes with an introduction to EJB and other important Java EE technologies. Throughout the course, students will create code for an online store. Students will learn not only specific topics and APIs but also how to fit the pieces together into a complete application.

Supported platforms include Eclipse/Tomcat, GlassFish, JBoss AS, IBM Rational Application Developer (RAD) / Websphere and Weblogic AS.
