J2EE Applications

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
