Java EE 5 (JEE - including EJB3)

J2EE Training Overview

nTier's intense Java EE 5 training course teaches Java programmers how to develop enterprise applications using the ease of development features introduced in Java EE 5. Students will learn how to create dynamic web applications with JSP, Java Servlets, JSTL, and JSF. They will use JAX-WS to develop SOAP based web services. Students will learn about session and message-driven EJBs, as well as the new Persistence API. They will also be introduced to JavaMail, Java Message Service, Java Transaction API, and Java Management Extensions.

J2EE Training Learning Objectives

• Describe the architecture and use of JEE technologies.

• Write web applications that combine Java Servlets, JavaServer Pages, and JavaBeans using the Model-View-Controller architecture.

• Develop web applications using the component-based and event-driven JavaServer Faces framework.

• Send and receive asynchronous messages with the Java Message Service.

• Interface with mail servers with JavaMail.

• Describe the Enterprise JavaBean architecture.

• Write session and message-driven EJBs.

• Access a relational database with the Java Persistence API.

• Handle transactions with the Java Transaction API.

• Integrate legacy systems with JAX-WS web services.
