Java Training Overview
The Java 2 Enterprise Edition (J2EE) platform offers a wide-ranging architecture for enterprise computing. It has many well-known and sophisticated technologies: servlets, JavaServer Pages (JSPs), Enterprise JavaBeans (EJBs) and Java Message Service (JMS), to name just a few. Before plunging into this alphabet soup, see how the parts all fit together in a complete computing model. This presentation course shows you what problems each technology solves and poses, as well as how they work together to create enterprise systems. This course is an important prerequisite to further training in any of those areas.
Java Training Prerequisites
Basic familiarity with the issues of enterprise computer systems, as developer or manager, is required. So is some familiarity with Java.
Java Training Course duration
1 Day
Java Training Learning Objectives
After completing this course a student should:
- Understand what J2EE is.
- Be able to identify the standards that underlie J2EE.
- Know what components and containers are, what benefits they offer and how they work together.
- Understand the major layers of an enterprise system, their roles, and the J2EE technologies used in each.
- Understand the basic architecture of servlets, JSPs, EJBs, JMS and JDBC.
- Understand how servlets and JSPs are related, how they differ and where each is best used.
- Be able to identify the various types of Enterprise JavaBeans and explain how they differ.
- Be able to identify and distinguish the two basic messaging models.
- Know what JDBC is and where it is used.
