Duration: 5 Days

In this comprehensive course, you will learn how to design and program servlets and JSPs, including all the important concepts and hands-on labs that will have you building working server-side applications. You will gain core JEE knowledge and skills used as the foundation for developing production-quality web applications to a basic level. Throughout this training, you will be confronted with common web application design problems and given the tools you will need to solve them, such as JEE design patterns. You will also be exposed to a range of JEE and web technologies such as Servlets, JSPs, EJBs, JNDI, XML, and advice on when and how to use them. You will learn about the capabilities of servlets, their advantages, servlet architecture, and session management. You will also learn about JSP syntax, deployment, and application models, how to use Java as a scripting language, how to use custom tags, and how to build robust and capable web applications using Servlets and JSP.

You will begin with web application architecture. A major part of the course is spent on servlets and JavaServer pages (JSP). You will cover interacting databases using JDBC, Java's database access technology. The course includes an introduction to web services. You will create code for an online store and learn not only specific topics and APIs but also how to fit the pieces together into a complete application. You will leave the course armed with the required skills to design and build scalable, secure, maintainable web applications.
