Benefits to you

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.

 

Participate in Hands-On Labs

By learning through hands-on exercises via structured labs, you'll get a chance to explore EJB-Lite session bean components, which can be used with container-managed transactions. You'll perform lab exercises using the NetBeans IDE and WebLogic Server.
