Java EE workshop

Accueil » Formations » Java » Java EE workshop

Java Enterprise Edition appeared at the end of the 90's and brought to the Java language a robust platform for business applications.
This workshop proposes to examine by practice how to integrate all the bricks and specifications of Java EE to realize a robust and maintainable enterprise application through a complete case study.
Attention, to be efficient, this workshop presupposes that the trainees have a good practice of Java with Eclipse, Web applications with Java (Servlet/JSP) and finally a knowledge -or a minimal practice- of advanced Java EE concepts: JPA, EJB, JSF.

    Programme

    Introduction

    • Overview of Java EE layers and services (reminders)

    Design

    • Discovery of the case study. During this phase, trainees realize the UML models of the application: use cases, class models, services and components…

    Setting up the environment

    • Installation of servers and development tools (JBoss server, MySQL, Eclipse WTP)
    • Applying deployment and testing principles

    Implementation of the application layer with EJB3

    • EJB Session Stateless, Statefull (reminders)
    • Local and remote interfaces
    • Annotations
    • Principle of calling an EJB with JNDI. Trainees realize the application services with EJB3

    Implementation of persistence with JPA (Java Persistence API)

    • Develop and test an entity (EJB Entity, EntityManager)
    • JPQL query language. Trainees implement and test the persistent business model of the application with JPA Entity

    Distributed component techniques

    • Presentation of the principles and techniques
    • Stub or Skeleton technical classes
    • Proxy pattern
    • Illustration with RMI, CORBA and EJB

    Implementation of Web Services

    • Reminders: SOA, Web Service, WSDL, SOAP, JAXB; Trainees transform an EJB into a Web Service and test it
    • Design pattern: Data Transfer Object (DTO)

    Implementation of the Web layer

    • Servlet/JSP (reminders)
      • Servlet/JSP MVC model
      • Scripting and JSP
      • Data Transfer Object and Value Object patterns
      • JSTL tag library (JSP Standard Tag Library)
      • Implementing its own tags
    • Trainees implement the Java EE Web part: the screens and their navigation

    Integration of JSF components

    • JSF (reminders)
      • Essential characteristics
      • Implementations: JSF-RI, MyFaces, IBM-JSF…
      • Component model of the user interface
      • Event-driven model
      • Data validation
      • Navigation model
      • Backing beans management
      • Internationalization
    • Trainees integrate in the web presentation layer rich components based on JSF

    Transaction management with JTA

    • Transactions managed by the container
    • Transactions managed by the bean
    • Concurrent access management
    • Trainees make the application robust by taking into account concurrent access and ACID transaction management.
