Business components development with EJB and JPA (Java EE)

Schedule notification

Category: Java, JEE, Android programming

The course covers the three Java EE technologies used for programming business logic: Enterprise Java Beans (EJB 3.1) and Java Persistence API entities (JPA 2) and Context and Dependency Injection (CDI, new in Java EE6).

The training provides its participants with instant possibility of applying their freshly acquired knowledge, as most of the class consists of guided, hands-on exercises and work on real-life scenarios. Participants will also benefit from practical tips on building and maintaining enterprise applications.

The focus of the training is solely the business logic layer. Those who wish to learn building complete applications should rather choose one of our full stack trainings, such as Glassfish, PrimeFaces. Building Applications for the Java Enterprise Edition 6.

      • built-in validators,
      • custom validators.
  2. The service layer:
    • resources and the JNDI tree: java:comp/env, java:global/env, java:app/env;

    • remote, local and no-interface views, remote calls and argument passing;
    • desktop applications as remote EJB clients;
    • services using JPA, persistence context propagation;
    • Container Managed Transactions and Application Managed Transactions;
