EJB 3 Training Overview

This EJB3 training course gives the experienced Java developer a thorough grounding in Enterprise JavaBeans. The Java EE standard for scalable, secure, and transactional business components. EJB 3.0 has reinvigorated this area of Java enterprise development, with dramatic improvements in ease of use and smooth integration with servlet-based or JSF web applications. This EJB3 training course treats the 3.0 specification, with a few notes on 2.1 compatibility but an emphasis on doing things the 3.0 way. DelhiGuru is the leading EJB 3 Training provided in Delhi NCR, by working profession in week end, and one-on-one, online individual and Group.

Students get an overview of the EJB rationale and architecture, and then dive right into creating session beans, message driven and entities. The new dependency-injection features of EJB3 cause perhaps the most confusion, so we work through a chapter devoted explicitly to DI and JNDI, and basically how components find each other to make an application. We study entities and the Java Persistence API in depth, and get a look at message-driven beans as well. The latter phase of this EJB3 training course covers advanced topics including transactions, security, and interceptors.

EJB 3 Training Prerequisites

All EJB3 training students should have solid Java programming skills and an understanding object-oriented Java and Java 5/6 language features. Experience with developing Java web applications is very helpful for this course, but not strictly required. Some knowledge of XML will be useful for writing the occasional deployment descriptor, but is not required.

EJB3 Training Objectives

  • Understand the role of EJB in the broader Java EE platform.
  • Describe the features that are implemented by an EJB container on behalf of application components.
  • Build stateless session beans as part of a service layer or SOA.
  • Build JPA entities to represent persistent data records within the Java application.
  • Develop systems of entities to manage complex data models including 1:1, 1:N, and N:N associations.
  • Manage transactional behavior of the application through declarative and programmatic techniques.
  • Invoke EJB sessions from Java web applications.
  • Use dependency injection and JNDI names to assemble complex web/EJB systems with minimal fuss and maximal flexibility.
  • Implement message-driven beans to process queued messages asynchronously.
  • Declare and/or program transaction boundaries, persistence contexts, and exception handling to properly control persistence logic.
  • Apply role-based authorization policies to EJBs
  • Build interceptors to perform generic processing before, after, or around EJB business-method invocations
  • Use EJB timers to defer processing or establish regularly scheduled tasks
