Java has taken the IT industry by storm over the past few years and there are now thousands of developers using it as their language of choice. This course offers existing Java developers further skills which will enable them to exploit the enterprise elements of this very capable programming environment.
Our JEE 7 training course provides an overview of the latest Java EE architecture, and intensive hands-on experience in the development and implementation of scalable distributed applications using Enterprise JavaBeans (EJB 3), Java Persistence Architecture (JPA) and Java Server Page (JSP) technologies – including Java Server Faces (JSF) and possibilities for integration with Web 2.0-enabling techniques like AJAX.
This course has been developed for real-world, commercial scenarios by our expert instructors. See below for detailed syllabus. If you have a technical question, please email email@example.com
