Training Description:

Java Platform, Enterprise Edition proposes a robust architecture to develop enterprise applications in Java programming language. It is also an umbrella under which a large number of technologies and standards coordinate with each other in robust, multi-tier, server-centric applications.

The present version - Java EE 5 - brings a host of new features that supersedes what was in Java 2 Enterprise Edition (J2EE) 1.4 for performance, latest technological advancements in the field and more than anything else, ease of development. They include Enterprise Java Beans 3.0, Java Persistence API (JPA), new XML based technologies for Web services, JavaServer Faces and Annotations support.

The training starts with a comparison of different distributed computing architectures. It then goes into client-server application building with Enterprise Java Beans and extends to web application development with JSP, Servlets and JavaServer Faces in multi-tier environments.

Training Objectives:

1. Develop moderately complex and secure web applications with using JavaBeans, JavaServer Pages, Servlets and JavaServer Faces.
2. Use, configure and manage JBoss and Tomcat application servers.
3. Implement Web services using JAX-WS.
4. Develop secure and transaction aware business tier components with Enterprise Java Beans.
5. Apply best practices used in multi-tier application development.

Target Groups:

1. Fresh graduates (or undergraduates close to completion of their degree programs) in related fields willing to persuade their careers as Java (Enterprise Edition) Developers.
2. Software Developers in other fields (like PHP or Microsoft .NET) willing to learn Java Enterprise Edition.

Prerequisites:

1. Participants should be familiar with writing simple programs in Java programming language (Java Standard Edition) or significantly exposed to one or more object oriented programming languages to grasp Java easily. This training does not teach basics of Java programming language but uses it.
2. General theories behind relational databases should be known. But a participant may not have prior experience in using specific database software.
3. Optionally, it is preferred that the participants are familiar with HTML and CSS. If not, participants will be directed to on-line tutorials which are not difficult to self study.

Communication Language:

English (With Sinhala explanations if requested)

Duration:

10 Days

Facilitator:

Kamal Wickramanayake (Profile)

Notes:

1. Participants will write a mini application of their own taken into consideration all what they learn.
2. Delivery of the training will be learner centric. Multiple delivery techniques will be used - not just lectures.
3. Participants will go through an MCQ based quiz at the end of the program.
4. To facilitate easy understanding, delivery of the training may not cover the content shown below in the exact order.
5. NetBeans IDE, Sun Java System Application Server, Tomcat and JBoss will be utilized for exercises.
