Developing Applications with Java EE Course Overview The Developing Applications with Java EE course introduces delegates to the Java Enterprise Edition API,up to version 7. It explains the core JEE technologies and how they can be used to build large scale web based applications. It also includes an overview of Enterprise Java Beans,the Java Persistence API and JEE security. Delegates will learn how to develop Java systems that create front end web pages using tools such as Servlets,Java Server Pages and WebSocket,and develop back-end components using EJB,CDI and Bean Validation. In addition,we will show how technologies such as JSON,JMS and Restful Web Services can be integrated into the overall solution. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
TARGET AUDIENCE:
Who will the Course Benefit? The Developing Applications with Java EE course is aimed at those who need to develop robust,flexible,extendable and maintainable software using the Java enterprise architecture. Roles include programmers,designers,architects,testers and anyone who needs a good understanding of the Java Enterprise Edition solution.
COURSE PREREQUISITES:
