JV248: Java and J2EE FastTrack (4*-5 days)

Course Overview

This course is an intensive four or five-day course designed to enable existing developers and programmers to rapidly become productive within J2EE environments. The first part of the course provides non-Java or new to Java programmers with an overview of the features of Java required for building enterprise applications. The second part of the course provides an intensive overview of J2EE to allow the student to begin developing distributed Java applications with the help of JNDI, Java Server Pages, Servlets, Tag Libraries, EJBs, JDBC, XML and more.

The course also briefly covers the essential information you need to know to understand the important emerging Web Services technologies: SOAP, the Simple Object Access Protocol; WebServices; and UDDI, the Universal Description Discovery and Integration system. It also gives practical steps and ideas for getting started with XML and using it within your projects, including a number of small exercises and demo applications to reinforce the theoretical material covered in the lecture material.

This course is approximately 60% structured lecture material and 40% hands-on labs and exercises.

Audience

Software developers, designers and architects interested in hands-on exploration of Java and enterprise and advanced aspects of Java.

Course Objectives

By the end of the course, attendees will:

• understand the Java language including native types, objects and flow control
• be able to design, develop, compile and run simple Java applications using the JDK
• understand some of the OO concepts behind Java (vs. procedural languages such as PL/SQL)
• understand the breadth or the Java class libraries and some specific details on some of the important classes
• understand the concepts associated with using an IDE
• understand the various help sources available to enable them to go further
• understand how to build robust, secure distributed systems using advanced Java programming
• be able to develop flexible data-aware applications using Java Database Connectivity (JDBC)
• know how to leverage Remote Method Invocation (RMI) to provide pure Java distributed applications
• understand how to connect to industry-standard directory and naming services using JNDI
• understand how to build enterprise components using Enterprise Java Beans (EJBs)
• have learnt how to leverage the power of Java and XML to build enterprise applications
• understand and be able to use several commonly used parsing technologies including SAX, DOM and JDOM
• understand the SOAP message structure
• discover the registry for looking up services: UDDI
• understand the functionality of Web services using WSDL

Pre-requisites

To successfully complete all workshops fully, attendees will need to have previous exposure to some programming languages, OO being preferable.

*For the 4-day course, time permits only a very brief revision of Java. Attendees must have previous exposure to Java.

Students with no or minimal Java experience may wish to consider attending one of the following courses instead of this one:
