Description

This course will allow you to develop enterprise web projects based on the Java EE platform. You will discover MVC architectures through the implementation of a presentation layer based on JSP then on JSF 2. You will discover the mechanisms of Servlet, learn to persist your data and secure your Java applications. You will implement the Eclipse IDE in order to build and deploy your solutions on the various Java EE application servers on the market such as JBoss Wildfly or WebSphere.
