Enterprise Java Beans 3.0

Home > Training Programmes > Programming > Enterprise Java Beans 3.0

Overview & Objectives:
Enterprise JavaBeans (EJB) technology is the server-side component architecture for Java/J2EE. It enables rapid and simplified development of distributed, transactional, secure and portable Java applications. In this course, you will learn how to develop several types of EJBs, including session beans, entity beans, and message-driven beans. The course is taught using the EJB 3.0 framework.

Course Duration:
3 Days (Part-time or Fulltime available)

Who should attend:
 1890 Java Developer or equivalent experience working with Java, JavaServer Pages (JSP), and Servlets.
