| Description |
This
course covers the issues of designing and implementing
E-Businessenterprise applications using the J2EE
1.4 framework and the WebSphere Application Server
5.0. The development will be done using the Rational
Application Developer (RAD/WSAD) 5.0 tool. Other
topics that are covered include the J2EE specification,
the J2EE architecture, the Sun BluePrintsTM Design
Guidelines for J2EE and all the major APIs for the
J2EE 1.4 framework.
This course has been specially designed for professionals looking to build large-scale, scalable, robust, secure, distributed E-Business systems using the J2EE platform. This course may be taken in lieu of the Introduction and Intermediate EJB courses. In addition, this course covers all other J2EE technologies such as JMS, XML, JNDI, JDBC, etc. |

| Objectives |
This course aims to teach a set of advanced skills necessary to implement robust, scalable, reusable e-business objects and secure enterprise applications using the J2EE framework. As part of this course, attendees will implement a comprehensive E-Business application that integrates various J2EE components. The application will be built using a multi-tiered architecture. The business tier will be implemented using EJB, the presentation tier Servlets and JSP, and the client tier Web browser. The data interchange format will be built using XML. The messaging part of the application will be built using JMS. This course also provides a comprehensive coverage of issues in the J2EE architecture and good practices and patterns. On completion, attendees will be able to:
-
Develop robust and industrial-strength enterprise applications using J2EE
-
Develop business objects using Enterprise JavaBeans (EJB)
-
Master the J2EE architecture
-
Master design principals and patterns
-
Master the J2EE APIs
-
Build Session and Entity beans for the enterprise
-
Build Servlets, JSP for the presentation tier
-
Use XML to structure and exchange enterprise data
-
Package web components in a Web Archive (WAR) file
-
Package EJB components in a Java Archive (JAR) file
-
Package WAR and JAR files into an Enterprise Archive (EAR) file
-
Use the deployer tool to deploy applications (EAR files) on a J2EE server
