Java EE 7: Front-end Web Application Development

Course code: JE7FE1

Duration:       40 Hours

Java EE 7: Front-end Web Application Development training helps you explore building and deploying enterprise applications that comply with the Java Platform, Enterprise Edition 7 Web Profile. By taking this course, you'll gain hands-on experience building Java EE web applications. You will get the chance to create web-based user interfaces using HTML5 and JavaScript along with JSPs and servlets. Web-based user interfaces will use AJAX to communicate with RESTful web services you create; data will persist using JPA and optimistic locking. Java is one of the most widely used languages right from building simple desktop applications to enterprise scale processing, web applications and mobile computing.
