Overview
This course will integrate a combination of instructor-led discussions and interactive workshops to demonstrate the development and testing of server-side applications using J2EE v1.4 component model. This course will focus on illustrating the use of the WSAD v5.1 product for developing servlets, JSPs, JavaBeans and EJBs. This seminar will focus on: WSAD wizards, migration to v5.1, servlet and JSP component development, session, message and entity EJB development, J2CA and their adapters, Web Services framework, JMS and MQSeries, packaging and deployment issues, J2EE Design patterns and Struts development.
