Java EE - Enterprise Java

Scheduled Dates (sort by: location | date)

Course Overview

Java has taken the IT industry by storm over the past few years and there are now thousands of developers using it as their language of choice. This course offers existing Java developers further skills which will enable them to exploit the enterprise elements of this very capable programming environment, it also covers the key enhancements made to Java in versions 5 and 6.

Our Java EE (formerly J2EE) training course provides an overview of Java EE architecture, and intensive hands-on experience in the development and implementation of scalable distributed applications using Enterprise JavaBeans (EJB 3), Java Persistence Architecture (JPA) and Java Server Page (JSP) technologies - including Java Server Faces (JSF) and possibilities for integration with Web 2.0-enabling techniques like AJAX.

This course has been developed for real-world, commercial scenarios by our expert instructors. See below for detailed syllabus.

Audience

Experienced Java programmers who require the skills to develop enterprise applications.

Skills Gained

• How to build a modern web presentation tier, exploiting the latest JSF components and integrating rich client techniques.
• How to build better and simpler EJBs with EJB 3 and annotation techniques.
• How to leverage XML with better programming techniques and easier creation of web services.
• How to improve access to relational data with the Java Persistence API.
• How to manage transactions and security in a Java EE environment.
• Assess vanilla Java EE versus popular framework alternatives.

Hands On Exercises

Delegates receive hands-on experience of building Java EE applications, including:

• Building JSF components for web presentation, and integrating these into a fully working application.
• Managing security and transactions in a full-blown application server environment.
• Writing a business tier incorporating new-style Enterprise Java Beans.
• Experiencing the ease with which the business tier can be transformed into a web service layer.
• Creating a JPA mapping layer to an existing relational database.
• Exploring Java Messaging Services for synchronous and asynchronous application communication.

Prerequisites

Programming experience of the Java language as covered in our JavaSE course. Some prior contact with internet technologies is helpful, though not essential.

Course Outline

Building the web tier - Servlets, JSP and JSF

• Servlets
• Java Server Pages (JSPs)
• Java Server Faces (JSF) benefits
• Understanding JSF components
• Building the UI with JSF: component classes and rendering model
• Web application screen flow with the JSF navigation model
• JSF custom tags
• Integration with standard tag libraries
• Client and server-side validation
• Presenting data easily with Unified
• Expression Language and Backing Beans

Implementing the business tier with EJB 3.0

• Implementing stateless and stateful beans
• Abstracting the business service layer
• Injecting services with annotations
• Accessing beans locally and remotely
• Transforming session beans into web services
• Integrating applications with message driven beans

Persisting data with JPA

• No more entity beans: persistence units and entity classes
• Persistent access with an Entity Manager
• Annotation-driven OR mapping
• Managing multiplicity in relationships
• Entity inheritance strategies
• Querying data with JPQL

Container Services

• Transactions
• Container-managed transaction
• strategies
• Annotations for transactions
• Bean-managed transactions with JTA
• Security on the Java EE platform
• Metadata annotations, declarative and
• programmatic approaches
• Authentication and authorisation
• mechanisms in the web and EJB tiers
• Protecting resources
• Propagating security identities

Java Messaging Services (JMS)

• Synchronous message management
• with session beans
• Asynchronous message reception with
• message driven beans
• Point-to-point and publish-subscribe
• application models
