This 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 course treats the 3.0 specification, with a few notes on 2.1 compatibility but an emphasis on doing things the 3.0 way. Students get an overview of the EJB rationale and architecture, and then dive right into creating session beans 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 the course covers advanced topics including transactions, security, and interceptors. This version of the course is designed to work with the Java EE 5 SDK, Update 7, which includes the GlassFish application server, version 2.1, and TopLink as the JPA provider. Variants of the course are also available with specific support for recent versions of JBoss and WebLogic. This course shows Java-1.4 developers the new language features in Java 5 and 6, and, more importantly, illustrates best programming practices as they've been affected by these new features. This is an accelerated course that assumes long experience with earlier versions of Java. Students will leave familiar with various new bits of syntax, and also with an understanding of the exciting new options they have for API design and general-purpose Java 6 coding.
Plenty of experience with Java programming using the 1.4 SDK is essential Java Training Learning Objectives
