Course Description |
||
The Enterprise JavaBeans 3.0 specification is a deep overhaul of the EJB
specification that is intended to improve the EJB architecture by
reducing its complexity from the developer's point of view. It leverages
annotations (introduced in Java 5) and Object-Relational Mapping (ORM)
technologies to eliminate the dependence on complex EJB APIs, allow POJO
(Plain Old Java Object) based development, and provide an effective
technology for creating distributed, transactional components, and for
mapping relational data to an object schema. This course provides
thorough coverage of the EJB3 technology including new concepts such as
the use of annotations and the use of Dependency Injection to initialize
references. This course also includes in-depth coverage of managing
persistence using the Java Persistence API (JPA). It uses hands-on labs
and a well-paced approach to make this complex technology understandable
in an accelerated fashion. You will come away with a comprehensive
understanding of EJB and the important issues that need to be considered
to use it in real world applications.

Complimentary Skills to have along with Java
- If you are an experienced Java developer, learning a complimentary language to Java should come much more naturally. As an example JetBrains recently created the Kotlin programming language which is officially supported by Google for mobile development. Kotlin compiles to Java bytecode and runs on the JVM; it's purported to address many of Java's shortcomings... |
