Java EE: EJB 3.0 in the Enterprise, Part 2 of 3

Course description

This course takes you beyond the fundamentals of Enterprise Java Bean (EJB 3.0) programming using Eclipse. In this course, you will learn about building message-driven Beans, EJB Security, utilizing Web Services technologies like JAX-WS, and managing distributed transactions. You will also be exposed to Java Interceptors, EJB Timer service, Hibernate JPA caching, EJB design patterns, and deployment.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course is intended for intermediate to advanced Java programmers. System architects will find the advanced concepts especially beneficial in designing a framework. Students should have good Java programming knowledge and should be familiar with web application programming, including servlets and JSPs.
