J2EE

Training Course Objectives:
There was a time when every company would design its own infrastructure for running its applications to provide services such as scalability, security, transaction management, data access pooling etc. Now, for Java applications, this is unnecessary, as the Java 2 Enterprise Edition provides a standard to which vendors must adhere to in order to provide an environment which offers all of these services and more.
During this hands-on course, participants will gain the knowledge and skills to begin developing server-side Java applications based on the Enterprise Java component technologies; Java Database Connectivity (JDBC), Servlets, JavaServer Pages (JSP) and Enterprise JavaBeans (EJB). Emphasis is placed on techniques and practices to develop scalable, transactional and secure n-tier enterprise applications. In particular, the course does not shy away from the pitfalls of EJBs, describing in detail where this technology is appropriate, demonstrating architectural and design patterns to mitigate the effects of working in a distributed environment, and summarising some of the possible alternatives to EJB.
