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 - presented in
a clear and effective manner. It starts with the basic concepts and APIs
of EJB and then continues on with complex topics such as message driven
beans and transactions. New concepts such as the use of annotations and
the use of Dependency Injection to initialize references are covered in
depth. The course also includes a solid introduction to developing
persistent entities using the Java Persistence API (JPA).

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... |
