J2EE Applications
Introduction
JBoss and Tomcat are now a well-established alternatives for deploying
distributed, scalable enterprise applications. This course demonstrates
how to build applications for both the Tomcat Web container and the JBoss
application server using open source tools such as Ant, and then to then
test and deploy those applications. Throughout the course, students will
build an end to end J2EE application. They will also see some of the
common design patterns that can be applied in Java applications.
Course Objectives
By the end of the course you will be able to:
-
Understand the J2EE architectural paradigm, and appreciate how
it can be used
-
Develop and deploy Java Server Pages, Servlets and Java Beans
within a web container
-
Be able to implement the Jakarta Struts framework
-
Use JNDI to locate distributed objects, including enterprise
Java beans, and application server specific components
-
Develop and deploy Entity Enterprise Java Beans
-
Develop and deploy Session Enterprise Java Beans
-
Appreciate the alternative persistence strategies, identifying
the pros and cons of each
-
Deploy a complete J2EE application within a J2EE compliant
application server
